I don't do a great deal of web browsing, so I've only bothered to stick a few common annoyances into my DNS server. Some of them are very old, I don't know if they still exist. This is in the named.conf file: ## advert blocking: zone "adimages.com" { type master; file "dead.zone"; }; zone "admonitor.com" { type master; file "dead.zone"; }; zone "adsfac.net" { type master; file "dead.zone"; }; zone "advertising.com" { type master; file "dead.zone"; }; zone "amazingmedia.com" { type master; file "dead.zone"; }; zone "casalemedia.com" { type master; file "dead.zone"; }; zone "clickagents.com" { type master; file "dead.zone"; }; zone "commission-junction.com" { type master; file "dead.zone"; }; zone "doubleclick.net" { type master; file "dead.zone"; }; zone "doubleclick.com" { type master; file "dead.zone"; }; zone "adwords.google.com" { type master; file "dead.zone"; }; zone "googlesyndication.com" { type master; file "dead.zone"; }; zone "fastclick.net" { type master; file "dead.zone"; }; zone "infospace.com" { type master; file "dead.zone"; }; zone "mediaplex.com" { type master; file "dead.zone"; }; zone "msads.com" { type master; file "dead.zone"; }; zone "ads.optusnet.com.au" { type master; file "dead.zone"; }; zone "qksrv.net" { type master; file "dead.zone"; }; zone "ads.x10.com" { type master; file "dead.zone"; }; zone "adserver.yahoo.com" { type master; file "dead.zone"; }; #zone "yimg.com" { type master; file "dead.zone"; }; And this is the dead.zone file: $TTL 86400 @ IN SOA ns.localdomain. hostmaster.mail.localdomain. ( 200 ; serial 28800 ; refresh 7200 ; retry 604800 ; expire 86400 ; ttl ) IN NS ns.localdomain. Yep, that's the whole thing (9 or 10 lines worth, if you want to get rid of a carriage return). Look-ups for any of the above domains, or sub-domains of them, result in an instant "no answer" answer. This one DNS server does the job for all the PCs on the network. -- Test running FC6 & FC5, and still using FC4. I delete all private mail, unseen. I read from the list.
