RE: Some hosts not resolving from No-IP by our DNS servers
Yes, thank you. The user entered the domain incorrectly. The oa.no-ip.info +trace resolves correctly. -Original Message- From: Dan Durrer [mailto:d...@vitalwerks.com] Sent: Wed 3/9/2011 1:46 PM To: Chuck Swiger Cc: Frank Pikelner; bind-users@lists.isc.org Subject: Re: Some hosts not resolving from No-IP by our DNS servers Yeah.. in-ip.info is probably supposed to be no-ip.info?

Yeah.. in-ip.info is probably supposed to be no-ip.info?

Re: Some hosts not resolving from No-IP by our DNS servers
If I am not mistaken, when you do +trace, the trace actually comes from your machine running 'dig', and not the DNS resolver itself. (Others on list please correct me) Can you perform the same 'dig' query from the DNS server, without specifying which resolver to use? This smells like the DNS server itself is having trouble communicating to the outside. I would start from there to make sure the DNS server itself can resolve these names. Also make sure recursion is enabled. On Wednesday, March 9, 2011, Frank Pikelner wrote: > > > > > > > > > > > Hello, > > I'm having a problem resolving several hosts from NO-IP.
