OpenDNS: A more secure, reliable, and up-to-date DNS service

Whether you're a parent wanting to filter some of the websites your child visits or a small business looking for a way to keep employees off Youtube, OpenDNS may be your solution. I've been using the service for a few months and love it.

Firstly, it tends to get updates faster than any other DNS servers I've ever used. So for someone like me, who is always working on new websites, it is important to be able to get to those websites by hostname as quickly as possible. OpenDNS seems to get updates within minutes. In the past, I've waited over a day for DNS to propagate on some sites using my ISP's DNS servers, and as a rule of thumb it can take up to 72 hours for DNS to propagate fully.

Now the downside to this is even though you can get to the website pretty easily, most of your viewers aren't using OpenDNS servers. They will have to wait, but at least you'll be able to construct a site while they are waiting. So, this isn't really a downside for you, it's just an inherit downside that comes from waiting on DNS.

Another advantage openDNS offers is that one can manually control DNS entries for a network. This is all handled from a very nice configuration page after you create an account. For instance, I can't stand and pretty much don't want any computers in my house browsing to that site. I've worked on too many computers loaded down with spyware, and a good number of them had MySpace shortcuts on the desktop or the MySpace instant messenger app installed. This could be a coincidence, but I think not. So, I can just block that site. I enter the domain name, save the settings, and within 3 minutes none of the computers on my network can get to

All that one has to do is create a free account at, add your network, and then change your DNS server settings. Subscribe to my blog. I will be posting a tutorial on changing DNS servers later this week. I will also be describing a bit more about using openDNS on a dynamic IP and some of the things that can be done to help make living with a dynamic IP less of a headache.
