DNS Not Resolving

[HogHunter]

Last night my hosting facility changed backend providers. I got a slew of new IP addresses. Well everything is working fine for those Domains that are not being managed on my internal DNS machines. The ones that I have on my DNS timeout before responding.

I checked and if I directly query the server for a name it gives the right response. But if I ask via normal DNS query, I get a timeout.

The tool I've been using to test it is

http://network-tools.com/nslook/Default.asp

When I use 74.xxx.nnn.53 (My DNS server) for the server I get answers that are correct for GetEventPhotos.com. If I use that same page with server value of 198.6.1.1 (UUNet DNS Server) I get a timeout looking up GetEventPhotos.com. Any help would be welcome.

I get the right answers and the same with the web page, so perhaps the TTL hadn't expired when you tried?

# nslookup - 198.6.1.1
> set type=ns
> geteventphotos.com
Server: 198.6.1.1
Address: 198.6.1.1#53

Non-authoritative answer:
geteventphotos.com nameserver = ns43.domaincontrol.com.
geteventphotos.com nameserver = ns44.domaincontrol.com.

Authoritative answers can be found from:
ns44.domaincontrol.com internet address = 208.109.255.22
ns43.domaincontrol.com internet address = 208.109.78.180
> set type=a

http://www.geteventphotos.com

Server: 198.6.1.1
Address: 198.6.1.1#53

Non-authoritative answer:

http://www.geteventphotos.com

canonical name = geteventphotos.com.
Name: geteventphotos.com
Address: 74.223.220.53

Unfortunately, I needed to fix that domain so I moved the DNS to another DNS server that I knew was working. With that in mind, I do have a similar domain that is not working, SEEMUG.COM. It is managed via the same DNS server that the other one was.

By the way, thanks for the input.

Yeah, that ones failing.

Firewall port 53 TCP/UDP would be the first suspect.
