* 3.1 KX RDATA format
|
||
|
|
|
||
|
|
The KX DNS record has the following RDATA format:
|
||
|
|
|
||
|
|
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
|
||
|
|
| PREFERENCE |
|
||
|
|
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
|
||
|
|
/ EXCHANGER /
|
||
|
|
/ /
|
||
|
|
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
|
||
|
|
|
||
|
|
where:
|
||
|
|
|
||
|
|
PREFERENCE A 16 bit non-negative integer which specifies the
|
||
|
|
preference given to this RR among other KX records
|
||
|
|
at the same owner. Lower values are preferred.
|
||
|
|
|
||
|
|
EXCHANGER A <domain-name> which specifies a host willing to
|
||
|
|
act as a mail exchange for the owner name.
|
||
|
|
|
||
|
|
KX records MUST cause type A additional section processing for the
|
||
|
|
host specified by EXCHANGER. In the event that the host processing
|
||
|
|
the DNS transaction supports IPv6, KX records MUST also cause type
|
||
|
|
AAAA additional section processing.
|
||
|
|
|
||
|
|
The KX RDATA field MUST NOT be compressed.
