This may also be called DNS remapping. Essentially, when your computer asks your router what the IP address for www.AnnoyingAdHoster.com
is, it returns a fake IP address, which in turn causes the ads to fail loading.
This is the same as what AdFree does, but in your router instead of your phone.
Adblock Plus is a nicer solution, as it actually modifies the webpage a bit to completely remove the ad space so you won't get weird error 404 whitespaces all over the site.
Tech talk: yeah, I know it doesn't return a fake IP address, 127.0.0.1 is in fact a very real IP address and something I use quite a bit for service testing, but I igured explaining how it works isn't relevant for blocking ads
