I did suggest squid but we already have a content filter/logging system 
on the firewall and its admin tells me it isn't compatible with squid 
(and he does know what he's talking about). The issue has come about 
because the powers that be want totally open access to 
http://www.euronext.com where our shares are quoted and if we allow this 
the ads are going to cause problems with the firewall. The DNS trick 
seems the easiest way round it and has the additional benefit of 
reducing useless traffic hitting the firewall and the not very fast (2M, 
but for a company of 6000 employees!) line it's connected to.

Anyway I've modified one nameserver and the firewall admin and I have 
pointed our own PCs at it so we'll see how it goes, it hasn't caused me 
any problem yet.

Thanks for the replies,

Regards, Ian
