Ah. you said "a .com nameserver'. Thought you meant 'any nameserver in the .com hirerarchy', as disinct from 'one of the servers for the .com TLD/zone' Yup, an agreement it is. the A records only for hosts within a zone you are authoritative for, _or_ glure records for a nameservr that is in a zone sub- delegated from something you are authoritative for. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
