A lot of enterprises do not run even the same operating system or management software for their internal non-IANA fakeroot systems as the external one, so one needs to be careful about the source of that data ;-) However, zone cut does of course not have to mean server change, so, if we continue at the same usual practice of cutting at _protocol and then running a separate zone on the same server, the Additional is still sent with signatures. Test case: dig _phantasy._sctp.besserwisser.org SRV +dnssec +norec @primary.se ...which returns: _phantasy._sctp.besserwisser.org. 27 IN SRV 0 0 4711 some.sub.besserwisser.org. Name server primary.se holds besserwisser.org, _sctp.besserwisser.org, sub.besserwisser.org and primary.se. All are signed and the delegations are secure[0]. Asking for a SRV record as above returns data from the two children, the zone for the name server, and implicitly (if this had been a full-service resolver) DNSKEY and RRSIG materials for besserwisser.org as well, because they of course are needed to validate the chain from the SEP. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE +46 705 989668 The PILLSBURY DOUGHBOY is CRYING for an END to BURT REYNOLDS movies!!
