[Pdns-users] CNAME Resoluion

[Tony Annese]

Those were wildcard entries for the whole domain icfd3.org.

I’ve removed those and get the same behavior. It also doesn’t explain why barracuda058130353572.icfd3.org does resolve.

PDNS is my master server and ns.whidbey.net/ns.whidbey.com are my slaves. I just added testing.icfd3.org and it was pushed out to the 2 slaves but the CNAME for sip.icfd3.org isn’t even being pushed out to the slaves.

Thank you, because that now makes it possible to help you:

$ dig +norec @ns.whidbey.net. sip.icfd3.org. any

You cannot have other resource records alongside a CNAME.  That's a requirement of the DNS, not of Powerdns specifically.

You should put A/AAAA records there.  Or if you want to avoid the duplication of information, you can look into ALIAS records which do this for you.
