Tired of online ads like I am? I have Firefox’s Adblock Plus and Safari AdBlock installed on my computer, but it becomes rather annoying to keep installing these applications on my multiple machines as well as every time I format them. To make ad blocking simpler I opted to use OpenDNS to block ads on the DNS level. To make this hack work you must configure your router to use OpenDNS’s servers (trust me you will want to do this anyway – their servers are FAST!) by following the OpenDNS tutorials. Secondly you must signup for a free OpenDNS account so you can setup network filters.
