Re: Should a nameserver know about itself?

RFC 1034: ``The administrators of both zones should insure [sic] that the NS and glue RRs which mark both sides of the cut are consistent _and remain so_.'' (Emphasis added.) As for the frequency of changes: Yes, you have to be notified whenever the server's IP address changes. On the other hand, you're already dealing with changes in the NS names. Sensibly chosen in-zone NS names (a.ns, b.ns) have the advantage of lasting forever. The overall effect on the frequency of changes could be positive or negative. ---Dan
