Re: CNAME Issue - Whether to use CNAME-data or Response-Flag
From: Doug Barton <dougb_at_nospam>Date: Fri Apr 09 2010 - 19:49:40 GMT
To: Steven Wilmot <steven@data-utilities.co.uk>
When I try to resolve mail.wilmot.me.uk against my local resolver (which
happens to be BIND 9.6.2-P1 atm) I get the expected result:
host mail.wilmot.me.uk
mail.wilmot.me.uk is an alias for wilmot.me.uk.mail.aaisp.net.uk.
wilmot.me.uk.mail.aaisp.net.uk has address 81.187.30.19
wilmot.me.uk.mail.aaisp.net.uk has IPv6 address
2001:8b0:0:30:230:48ff:fedb:25dc
Looking at the response from the local resolver with dig confirms that
it is as expected.
Querying your authoritative server also produces the expected result:
; <<>> DiG 9.6.2-P1 <<>> @primary-dns.co.uk mail.wilmot.me.uk a
; (2 servers found)
;; global options: +cmd
;; Got answer:

So I'm not sure exactly what problem you're reporting.
hth,
