Re: Is it a DNS problem?

Hi Greg,

I called Clearchannel and they said our ip address is not on their
blacklist. So the ball is back on our end. One thing I noticed on our dns
servers is that eventhough there are entries in the cached lookups for their
sites, they only show dns info....nothing for host(A). Other cached lookups
show both dns and host info.

Any idea? Thanks!


Richard

Thanks Greg. Yes, we can browse and do nslookup from a different ip. I
have Clearchannel's contact info so I'll give them a call. Thank again!

Hi Richard,

The most likely problem is that your IP address range is on a blacklist
that Clearchannel is using. A way to test this would be to try to
nslookup or browse to those web sites from a different IP address.

We have internal and external dns servers (2003). We can browse and do
nslookup on any sites except for sites that are hosted by
"clearchannel.com".

Clearchannel has the following dns and web servers and they host many
radio and tv stations on the same web servers:

dns servers:
dns1.clearchannel.com
dns2.clearchannel.com
ns1.clearchannel.com
ns2.clearchannel.com

web servers:
207.230.150.254
207.230.154.254
207.230.156.254

Here are some of their sites that we cannot get to:
www.kbig104.com
www.foxsports610.com
www.y92.com
www.talk960.com


When we do an nslookup we get the following:
DNS request timed out.
timeout was 2 seconds.

We can get to their sites using our separate dsl line that we use for
testing.

We have no filtering set in our firewall for their ip addresses. Could
this be an issue with our dns? Any help is appreciated. Thanks!

Richard
