where:
ID A 16 bit identifier assigned by the program that
generates any kind of query. This identifier is copied
the corresponding reply and can be used by the requester
to match up replies to outstanding queries.
QR A one bit field that specifies whether this message is a
query (0), or a response (1).
OPCODE A four bit field that specifies kind of query in this
message. This value is set by the originator of a query
and copied into the response. The values are:
0 a standard query (QUERY)
1 an inverse query (IQUERY)
2 a server status request (STATUS)
3-15 reserved for future use
AA Authoritative Answer - this bit is valid in responses,
and specifies that the responding name server is an
authority for the domain name in question section.
Note that the contents of the answer section may have
multiple owner names because of aliases. The AA bit
corresponds to the name which matches the query name, or
the first owner name in the answer section.
TC TrunCation - specifies that this message was truncated
due to length greater than that permitted on the
transmission channel.
RD Recursion Desired - this bit may be set in a query and
is copied into the response. If RD is set, it directs
the name server to pursue the query recursively.
Recursive query support is optional.
RA Recursion Available - this be is set or cleared in a
response, and denotes whether recursive query support is
available in the name server.
Z Reserved for future use. Must be zero in all queries
and responses.
RCODE Response code - this 4 bit field is set as part of
responses. The values have the following
interpretation:
0 No error condition
1 Format error - The name server was
unable to interpret the query.
2 Server failure - The name server was
unable to process this query due to a
problem with the name server.
3 Name Error - Meaningful only for
responses from an authoritative name
server, this code signifies that the
domain name referenced in the query does
not exist.
4 Not Implemented - The name server does
not support the requested kind of query.
5 Refused - The name server refuses to
perform the specified operation for
policy reasons. For example, a name
server may not wish to provide the
information to the particular requester,
or a name server may not wish to perform
a particular operation (e.g., zone
transfer) for particular data.
6-15 Reserved for future use.
QDCOUNT an unsigned 16 bit integer specifying the number of
entries in the question section.
ANCOUNT an unsigned 16 bit integer specifying the number of
resource records in the answer section.
NSCOUNT an unsigned 16 bit integer specifying the number of name
server resource records in the authority records
section.
ARCOUNT an unsigned 16 bit integer specifying the number of
resource records in the additional records section.

i.e., the parameters that define what is being asked. The section
contains QDCOUNT (usually 1) entries, each of the following format:

+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
where:
QNAME a domain name represented as a sequence of labels, where
each label consists of a length octet followed by that
number of octets. The domain name terminates with the
zero length octet for the null label of the root. Note
that this field may be an odd number of octets; no
padding is used.
QTYPE a two octet code which specifies the type of the query.
The values for this field include all codes valid for a
TYPE field, together with some more general codes which
can match more than one type of RR.
QCLASS a two octet code that specifies the class of the query.
For example, the QCLASS field is IN for the Internet.

TTL a 32 bit signed integer that specifies the time interval
that the resource record may be cached before the source
of the information should again be consulted. Zero
values are interpreted to mean that the RR can only be
used for the transaction in progress, and should not be
cached. For example, SOA records are always distributed
with a zero TTL to prohibit caching. Zero values can
also be used for extremely volatile data.
RDLENGTH an unsigned 16 bit integer that specifies the length in
octets of the RDATA field.
RDATA a variable length string of octets that describes the
resource. The format of this information varies
according to the TYPE and CLASS of the resource record.

5.2 NXT RDATA Format
The RDATA for an NXT RR consists simply of a domain name followed by
a bit map.
The type number for the NXT RR is 30.
1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

| next domain name /
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| type bit map /
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
The NXT RR type bit map is one bit per RR type present for the owner
name similar to the WKS socket bit map. The first bit represents RR
type zero (an illegal type which should not be present.) A one bit
indicates that at least one RR of that type is present for the owner
name. A zero indicates that no such RR is present. All bits not
specified because they are beyond the end of the bit map are assumed
to be zero. Note that bit 30, for NXT, will always be on so the
minimum bit map length is actually four octets. The NXT bit map
should be printed as a list of RR type mnemonics or decimal numbers
similar to the WKS RR.
The domain name may be compressed with standard DNS name compression
when being transmitted over the network. The size of the bit map can
be inferred from the RDLENGTH and the length of the next domain name.

An ISDN (Integrated Service Digital Network) number is simply a
telephone number. The intent of the members of the CCITT is to
upgrade all telephone and data network service to a common service.
The numbering plan (E.163/E.164) is the same as the familiar
international plan for POTS (an un-official acronym, meaning Plain
Old Telephone Service). In E.166, CCITT says "An E.163/E.164
telephony subscriber may become an ISDN subscriber without a number
change."
ISDN has the following format:
<owner> <ttl> <class> ISDN <ISDN-address> <sa>
The <ISDN-address> field is required; <sa> is optional.
<ISDN-address> identifies the ISDN number of <owner> and DDI (Direct
Dial In) if any, as defined by E.164 [8] and E.163 [7], the ISDN and
PSTN (Public Switched Telephone Network) numbering plan. E.163
defines the country codes, and E.164 the form of the addresses. Its
format in master files is a <character-string> syntactically
identical to that used in TXT and HINFO.
<sa> specifies the subaddress (SA). The format of <sa> in master
files is a <character-string> syntactically identical to that used in
TXT and HINFO.
The format of ISDN is class insensitive. ISDN RRs cause no
additional section processing.
The <ISDN-address> is a string of characters, normally decimal
digits, beginning with the E.163 country code and ending with the DDI
if any. Note that ISDN, in Q.931, permits any IA5 character in the
general case.
The <sa> is a string of hexadecimal digits. For digits 0-9, the
concrete encoding in the Q.931 call setup information element is
identical to BCD.
For example:
Relay.Prime.COM. IN ISDN 150862028003217
sh.Prime.COM. IN ISDN 150862028003217 004
(Note: "1" is the country code for the North American Integrated
Numbering Area, i.e., the system of "area codes" familiar to people
in those countries.)
The RR data is the ASCII representation of the digits. It is encoded
as one or two <character-string>s, i.e., count followed by
characters.
CCITT recommendation E.166 [9] defines prefix escape codes for the
representation of ISDN (E.163/E.164) addresses in X.121, and PSDN
(X.121) addresses in E.164. It specifies that the exact codes are a
"national matter", i.e., different on different networks. A host
connected to the ISDN may be able to use both the X25 and ISDN
addresses, with the local prefix added.

3.1 KEY RDATA format
The RDATA for a KEY RR consists of flags, a protocol octet, the
algorithm number octet, and the public key itself. The format is as
follows:
1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| flags | protocol | algorithm |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| /
/ public key /
/ /
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-|
The KEY RR is not intended for storage of certificates and a separate
certificate RR has been developed for that purpose, defined in [RFC
2538].
The meaning of the KEY RR owner name, flags, and protocol octet are
described in Sections 3.1.1 through 3.1.5 below. The flags and
algorithm must be examined before any data following the algorithm
octet as they control the existence and format of any following data.
The algorithm and public key fields are described in Section 3.2.
The format of the public key is algorithm dependent.
KEY RRs do not specify their validity period but their authenticating
SIG RR(s) do as described in Section 4 below.

+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
where:
VERSION Version number of the representation. This must be zero.
Implementations are required to check this field and make
no assumptions about the format of unrecognized versions.
SIZE The diameter of a sphere enclosing the described entity, in
centimeters, expressed as a pair of four-bit unsigned
integers, each ranging from zero to nine, with the most
significant four bits representing the base and the second
number representing the power of ten by which to multiply
the base. This allows sizes from 0e0 (<1cm) to 9e9
(90,000km) to be expressed. This representation was chosen
such that the hexadecimal representation can be read by
eye; 0x15 = 1e5. Four-bit values greater than 9 are
undefined, as are values with a base of zero and a non-zero
exponent.
Since 20000000m (represented by the value 0x29) is greater
than the equatorial diameter of the WGS 84 ellipsoid
(12756274m), it is therefore suitable for use as a
"worldwide" size.
HORIZ PRE The horizontal precision of the data, in centimeters,
expressed using the same representation as SIZE. This is
the diameter of the horizontal "circle of error", rather
than a "plus or minus" value. (This was chosen to match
the interpretation of SIZE; to get a "plus or minus" value,
divide by 2.)
VERT PRE The vertical precision of the data, in centimeters,
expressed using the sane representation as for SIZE. This
is the total potential vertical error, rather than a "plus
or minus" value. (This was chosen to match the
interpretation of SIZE; to get a "plus or minus" value,
divide by 2.) Note that if altitude above or below sea
level is used as an approximation for altitude relative to
the [WGS 84] ellipsoid, the precision value should be
adjusted.
LATITUDE The latitude of the center of the sphere described by the
SIZE field, expressed as a 32-bit integer, most significant
octet first (network standard byte order), in thousandths
of a second of arc. 2^31 represents the equator; numbers
above that are north latitude.
LONGITUDE The longitude of the center of the sphere described by the
SIZE field, expressed as a 32-bit integer, most significant
octet first (network standard byte order), in thousandths
of a second of arc, rounded away from the prime meridian.
2^31 represents the prime meridian; numbers above that are
east longitude.
ALTITUDE The altitude of the center of the sphere described by the
SIZE field, expressed as a 32-bit integer, most significant
octet first (network standard byte order), in centimeters,
from a base of 100,000m below the [WGS 84] reference
spheroid used by GPS (semimajor axis a=6378137.0,
reciprocal flattening rf=298.257223563). Altitude above
(or below) sea level may be used as an approximation of
altitude relative to the the [WGS 84] spheroid, though due
to the Earth's surface not being a perfect spheroid, there
will be differences. (For example, the geoid (which sea
level approximates) for the continental US ranges from 10
meters to 50 meters below the [WGS 84] spheroid.
Adjustments to ALTITUDE and/or VERT PRE will be necessary
in most cases. The Defense Mapping Agency publishes geoid
height values relative to the [WGS 84] ellipsoid.

4. The new DNS resource record for MIXER mapping rules: PX
The specification of the Internet DNS (RFC1035) provides a number of
specific resource records (RRs) to contain specific pieces of
information. In particular they contain the Mail eXchanger (MX) RR
and the host Address (A) records which are used by the Internet SMTP
mailers. As we will store the RFC822 to X.400 mapping information in
the already existing DNS name tree, we need to define a new DNS RR in
order to avoid any possible clash or misuse of already existing data
structures. The same new RR will also be used to store the mappings
from X.400 to RFC822. More over the mapping information, i.e., the
MCGAMs, has a specific format and syntax which require an appropriate
data structure and processing. A further advantage of defining a new
RR is the ability to include flexibility for some eventual future
development.
The definition of the new 'PX' DNS resource record is:
class: IN (Internet)
name: PX (pointer to X.400/RFC822 mapping information)
value: 26
The PX RDATA format is:
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
| PREFERENCE |
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
/ MAP822 /
/ /
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
/ MAPX400 /
/ /
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
where:
PREFERENCE A 16 bit integer which specifies the preference given to
this RR among others at the same owner. Lower values
are preferred;
MAP822 A <domain-name> element containing <rfc822-domain>, the
RFC822 part of the MCGAM;
MAPX400 A <domain-name> element containing the value of
<x400-in-domain-syntax> derived from the X.400 part of
the MCGAM (see sect. 4.2);
PX records cause no additional section processing. The PX RR format
is the usual one:
<name> [<class>] [<TTL>] <type> <RDATA>
When we store in DNS a 'table1' or a 'gate1' entry, then <name> will
be an X.400 mail domain name in DNS syntax (see sect. 4.2). When we
store a 'table2' or a 'gate2' table entry, <name> will be an RFC822
mail domain name, including both fully qualified DNS domains and mail
only domains (MX-only domains). All normal DNS conventions, like
default values, wildcards, abbreviations and message compression,
apply also for all the components of the PX RR. In particular <name>,
MAP822 and MAPX400, as <domain-name> elements, must have the final
"." (root) when they are fully qualified.

2.2. The Responsible Person RR
The method uses a new RR type with mnemonic RP and type code of 17
(decimal).
RP has the following format:
<owner> <ttl> <class> RP <mbox-dname> <txt-dname>
Both RDATA fields are required in all RP RRs.
The first field, <mbox-dname>, is a domain name that specifies the
mailbox for the responsible person. Its format in master files uses
the DNS convention for mailbox encoding, identical to that used for
the RNAME mailbox field in the SOA RR. The root domain name (just
".") may be specified for <mbox-dname> to indicate that no mailbox is
available.
The second field, <txt-dname>, is a domain name for which TXT RR's
exist. A subsequent query can be performed to retrieve the
associated TXT resource records at <txt-dname>. This provides a
level of indirection so that the entity can be referred to from
multiple places in the DNS. The root domain name (just ".") may be
specified for <txt-dname> to indicate that the TXT_DNAME is absent,
and no associated TXT RR exists.

3.3. The Route Through RR
The Route Through RR is defined with mnemonic RT and type code 21
(decimal).
The RT resource record provides a route-through binding for hosts
that do not have their own direct wide area network addresses. It is
used in much the same way as the MX RR.
RT has the following format:
<owner> <ttl> <class> RT <preference> <intermediate-host>
Both RDATA fields are required in all RT RRs.
The first field, <preference>, is a 16 bit integer, representing the
preference of the route. Smaller numbers indicate more preferred
routes.
<intermediate-host> is the domain name of a host which will serve as
an intermediate in reaching the host specified by <owner>. The DNS
RRs associated with <intermediate-host> are expected to include at
least one A, X25, or ISDN record.
The format of the RT RR is class insensitive. RT records cause type
X25, ISDN, and A additional section processing for <intermediate-
host>.
For example,
sh.prime.com. IN RT 2 Relay.Prime.COM.
IN RT 10 NET.Prime.COM.
*.prime.com. IN RT 90 Relay.Prime.COM.
When a host is looking up DNS records to attempt to route a datagram,
it first looks for RT records for the destination host, which point
to hosts with address records (A, X25, ISDN) compatible with the wide
area networks available to the host. If it is itself in the set of
RT records, it discards any RTs with preferences higher or equal to
its own. If there are no (remaining) RTs, it can then use address
records of the destination itself.
Wild-card RTs are used exactly as are wild-card MXs. RT's do not
"chain"; that is, it is not valid to use the RT RRs found for a host
referred to by an RT.
The concrete encoding is identical to the MX RR.

All times are in units of seconds.
Most of these fields are pertinent only for name server maintenance
operations. However, MINIMUM is used in all query operations that
retrieve RRs from a zone. Whenever a RR is sent in a response to a
query, the TTL field is set to the maximum of the TTL field from the RR
and the MINIMUM field in the appropriate SOA. Thus MINIMUM is a lower
bound on the TTL field for all RRs in a zone. Note that this use of
MINIMUM should occur when the RRs are copied into the response and not
when the zone is loaded from a master file or via a zone transfer. The
reason for this provison is to allow future dynamic update facilities to
change the SOA RR with known semantics.

Priority
The priority of this target host. A client MUST attempt to
contact the target host with the lowest-numbered priority it can
reach; target hosts with the same priority SHOULD be tried in an
order defined by the weight field. The range is 0-65535. This
is a 16 bit unsigned integer in network byte order.
Weight
A server selection mechanism. The weight field specifies a
relative weight for entries with the same priority. Larger
weights SHOULD be given a proportionately higher probability of
being selected. The range of this number is 0-65535. This is a
16 bit unsigned integer in network byte order. Domain
administrators SHOULD use Weight 0 when there isn't any server
selection to do, to make the RR easier to read for humans (less
noisy). In the presence of records containing weights greater
than 0, records with weight 0 should have a very small chance of
being selected.
In the absence of a protocol whose specification calls for the
use of other weighting information, a client arranges the SRV
RRs of the same Priority in the order in which target hosts,
specified by the SRV RRs, will be contacted. The following
algorithm SHOULD be used to order the SRV RRs of the same
priority:
To select a target to be contacted next, arrange all SRV RRs
(that have not been ordered yet) in any order, except that all
those with weight 0 are placed at the beginning of the list.
Compute the sum of the weights of those RRs, and with each RR
associate the running sum in the selected order. Then choose a
uniform random number between 0 and the sum computed
(inclusive), and select the RR whose running sum value is the
first in the selected order which is greater than or equal to
the random number selected. The target host specified in the
selected SRV RR is the next one to be contacted by the client.
Remove this SRV RR from the set of the unordered SRV RRs and
apply the described algorithm to the unordered SRV RRs to select
the next target host. Continue the ordering process until there
are no unordered SRV RRs. This process is repeated for each
Priority.
Port
The port on this target host of this service. The range is 0-
65535. This is a 16 bit unsigned integer in network byte order.
This is often as specified in Assigned Numbers but need not be.
Target
The domain name of the target host. There MUST be one or more
address records for this name, the name MUST NOT be an alias (in
the sense of RFC 1034 or RFC 2181). Implementors are urged, but
not required, to return the address record(s) in the Additional
Data section. Unless and until permitted by future standards
action, name compression is not to be used for this field.
A Target of "." means that the service is decidedly not
available at this domain.
