Well, I believe that for Yahoo you can do the same with scs.yahoo.com.
At least that is the host GAIM <http://gaim.sf.net> uses by default
for Yahoo.

And blocking access to external name servers is fairly easy, at least
if you only care about blocking 99.9-or-so-percent of the users. Only
allow TCP and UDP on port 53 to/from the internal caching DNS
server(s) - and of course any masters or slaves you may have.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
