Hi:

            You could download Iptstate and install it on your Linux Router.
Then connect and disconnect several times to Yahoo with a client machine
while monitoring on the Router with Iptstate.  Once you know the IP’s, just
block them. My understanding is that this is more efficient than using host
names anyway. Hope that helps.

Right. I should have checked that.
Aren't there any servers mentioned in the messenger setup (I don't use it
myself) ?
I just checked on cs.yahoo.com and that one exists but everytime I ping that
server I'm redirected to cs41.msg.sc5.yahoo.com (216.136.233.128).
I don't know if that's the same one for you ?
