[SOLVED] BIND... problem with linuxforums.org

[andy2008]

I have a server, well, actually two servers, both configured as mail/web/dns servers.
Anyway, bind is working as it should be, my LAN users use my DNS servers and every site is loading perfectly, I didn't receive any complaints...
But as it turns out, I found a problem and I can't understand what causes this "glitch".
I tried accessing Open Source and Linux Forums and none of my DNS Servers are able to resolve this domain. But using the DNS of two different providers, I'm able to see this it. Is there any logical explanation to this? How can this happen? Every domain out there is seen, except for this one.

Here is what named.log shows when I try to ping Open Source and Linux Forums

(on the last line, "mydomain.com" is actually my real domain name)

Never mind. I had the whole 174.0.0.0 class as a bogon network in named.conf. I removed it and linuxforums is now visible
