about resolving on a child zone
hello, I have the domain saying it's example.com. I defined a NS (and its A rcd) as below: my.example.com. IN NS mydns.example.com. mydns.example.com. IN A 11.22.33.44 Also I added this A record in both main DNS and the child zone's DNS (mydns.example.com). www.my.example.com. IN A 55.66.77.88 When I query for www.my.example.com, who will respond for it? the main DNS or that mydns? Can I set only www.my.example.com in main DNS while not in mydns? Thanks for your kind helps. Regards.

You should try it and see what happens. Use named-checkzone to check both copies of the zone for errors. In this case, the answer is that your main zone (example.com) will have an error, because it will have an A record below the "bottom" of the zone that is not a glue record. In other words, it will recognize that www.my.example.com belongs to my.example.com, not to example.com.

If, for example, this is an authoritative-only server, it's possible that named doesn't send any outgoing query (and in that case there should be no cache DB RRsets). > What should I activate or change on settings in order to get statistics on > above listed too? (I know this is not an answer to the question but) If your views aren't expected to have non-empty statistics, you don't have to worry about these things. --- JINMEI, Tatuya Internet Systems Consortium, Inc. ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Re: help on strange dig info
This one is a badly configured load balancer. The lookup sometimes succeeds as the glue from the parent zone is used. This however is not guarenteed to be the case and explict queries for the addresses of the nameservers will detect the problems causing subsequent queries to fail. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: mark_andr...@isc.org ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

There's a special exception made for "glue" records, since they're needed to prevent an infinite recursion. The parent zone will include this A record. -- Barry Margolin, bar...@alum.mit.edu Arlington, MA *** PLEASE don't copy me on replies, I'll read them in the group *** ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
