1 Root DNSKEY response test results:
3 Tests were run with BIND 9.6.0-P1 and NSD 3.2.2. BIND 9.6 gives back
4 "minimal response" answers for DNSKEY, NSD 3.2.2 does not.
6 For the full response case, note that the IPv4 glue is 16 bytes per
7 record, and IPv6 glue is 28 bytes per record. The full responses may
8 be truncated up to 404 bytes without setting TC.
12 a) "minimal response" is the size of the BIND 9.6 response (that is,
13 the DNSKEY response with only the answer section and the OPT RR.
14 b) "minimum no-tc response" is the size of the NSD 3.2.2 response,
15 minus the additional section, although including the OPT RR. This
16 is the minimum NSD response prior to setting the TC bit.
17 c) "full response" is the size of the NSD 3.2.2 response including
18 the additional section.
20 Note that the size of the authority section is predictable given a
21 fixed ZSK size (it varies by the size of the root NS RRSIG), and the
22 additional section size is a constant (404 octets).
26 KSKs are 2048 bits, ZSKs are 1024 bits.
