I use PeerBlock (former PeerGuardian) and, as a consequence, Yahoo Messenger (actually Pidgin) fails to connect every once in a while; PeerBlock reports the access being blocked because the destination IP is in one of the block lists. Where can I get a list of all IP ranges belonging to Yahoo Messenger so I can configure an "allow" rule in PeerBlock?
The following addresses appear to work:
These are the IP addresses to which scs.msg.yahoo.com maps. You can try one of them directly, but recent reports (on 6/19/2009) are that few, if any, are working. Note also that there is no guarantee that the server at an address that works now will not be upgraded next.
You can verify this list yourself by running one of the following commands:
Windows: nslookup scs.msg.yahoo.com
Linux/Unix/OS X: dig +short scs.msg.yahoo.com
You may also want to try to whitelist;
or if you can't whitelist domains, try;
