In the past, I used to set the DNS entries in computers to use Google (188.8.131.52 and 184.108.40.206). However, I have had some issues in the past, and think I give google enough information about myself already. I have switched to OpenDNS and have enjoyed my experience so far. However, the IP addresses are a little harder to remember, hence why I am making this tiny post.
