Depending on how tech-savvy you are, you may have heard about the DNS vulnerability that many DNS providers are working hard to fix. For more information about what DNS is, check out the Wikipedia page on it. Long story short, a hacker can attack an unpatched DNS server, forcing it to show you “bad” pages when you try to view something as simple as Google.com. Chances are, if you’re a typical home internet user, your DNS requests are handled by your internet service provider. Some ISPs haven’t fixed their DNS servers yet, making them still vulnerable to this kind of attack.
OpenDNS provides a third party DNS solution. I’ve been using their services for years for two main reasons. First off – they’re fast. If you’re connected on a 5+ Mbps broadband connection, chances are you’ll notice a speed increase when viewing certain pages. Secondly, they’re secure. Not only are they already on top of the DNS vulnerability mentioned above (they were one of the first), they also handle misspelled domain names (www.google.co gets turned into www.google.com) and also protect you from known phishing sites.
For more information, go to OpenDNS.com and look through their documentation. They provide all the instructions you need to get on your way to a safer internet. You can easily tell if you’re using OpenDNS as your DNS servers by looking at the link image on the sidebar. If you’re on the OpenDNS network, you’ll see a small blue checkmark. 🙂
