25% of our bandwith at work is used up by banner ads, cookies, and the rest of the junk filling the net.
I've come across a good listing of servers that only serve up junk.
Is there a way to add those to our DNS server and force the server to return that it's an unknown domain, so that when a webpage tries to pull an ad from ad.doubleclick.net, the banner ad is empty because the PC thinks that ad.doubleclick.net does not exist?
I could add ad.doubleclick.net to our firewall, and block it there, but Internet Explorer tries to hit the site over and over many times, causing a lot of local traffic, as well has having the user's browser hang while waiting for the site to respond. I dont like that option.
Next, I tried adding all the domains in our DNS and have them point to a server not running Apache, but then it causes a lot of dead hits to hit that server, and theres still the local traffic problem, and Explorer hanging while it waits for a response.
Next... have it point to 127.0.0.1... solves the traffic problem, but explorer still hangs.
The fastest response from IE is if you give it a dead domain. Put http://thisdomain.doesntexist1.com
in IE and it pops back immediately that theres nothing there. If I could have our DNS server return that theres no DNS record for ad.doubleclick.net (as well as a huge list of other domains) that would solve the problem. Is there an easy way to do this?
