25 * 3.1 KX RDATA format
26 *
27 * The KX DNS record has the following RDATA format:
28 *
29 * +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
30 * | PREFERENCE |
31 * +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
32 * / EXCHANGER /
33 * / /
34 * +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
35 *
36 * where:
37 *
38 * PREFERENCE A 16 bit non-negative integer which specifies the
39 * preference given to this RR among other KX records
40 * at the same owner. Lower values are preferred.
41 *
42 * EXCHANGER A <domain-name> which specifies a host willing to
43 * act as a mail exchange for the owner name.
44 *
45 * KX records MUST cause type A additional section processing for the
46 * host specified by EXCHANGER. In the event that the host processing
47 * the DNS transaction supports IPv6, KX records MUST also cause type
48 * AAAA additional section processing.
49 *
50 * The KX RDATA field MUST NOT be compressed.
