I have found a site that has a hosts file containing about 800 ad
servers. Each entry points to the loopback address 127.0.0.1. The
idea
is to put this on your workstation to stop some of the ads on
webpages.
Could I use this on my BorderManager server running DNS proxy to
accomplish the same thing for my entire network? What is the effect
of
having such a large hosts file? It seems I read something about thisfile should be as small as possible though I can't remember why.
Anyone
have any thoughts?

Thanks
Greg
