The button below detects if you're using OpenDNS or not. If you are not using it at home, I highly recommend you consider doing so. Particularly if you have kids that you want to keep from viewing sites that are not appropriate for them. To do this, you sign-up at their site, configure you DNS options, and then configure your home router to only hand-out their DNS servers. This last step is important so that all your, or your childs, devices get the OpenDNS DNS server addresses during the process of connecting to the Internet from your home.
