Is Norton AV 2009 preventing Symantec's IPs lookups?

So, I see one of Norton AV 2009 services is connecting to a certain IP. I went to, which among other great info, also provides the chance to perform ports and IPs lookups. I did a lookup on that IP and it keeps thinking and thinking and never performs the lookup. It only happens with this specific IP.

Could Norton AV being preventing such lookup? :o ???

Yes, Norton Antivirus might block the specific IP address.


Turn off the Norton Antivirus firewall and then check for the issue.
If the issue resolved then create a new firewall to rule to allow that specific IP address
