Being the father of five children under the age of 16 years old, with a home that has three computers, four iPhones and three iPod Touches, I’ve been experimenting with software over the past few years to trying to reduce the likelihood of porn inadvertently showing up on their screens. After trying some commercial software for content filtering a couple of years ago, that ended up slowing down our old computer, I have found something that doesn’t kill our computer, and as an added bonus is FREE – OpenDNS.

OpenDNS allows you to filter web content and block adult websites on the internet by simply changing the DNS servers that your computer or router uses. While not full proof (no solution is), it quite works well. After you’ve setup an account, you can specify the kinds of web sites you want to block or allow. You can also specifically allow web sites that may be grouped in a category you have blocked. You have all the control that you could ask for. If you want you can install on one computer in your home to let OpenDNS know if your IP address changes, so that it can continue to filter based on the criteria you’ve set in their control panel.

If you want, you can also enable logging so that you can keep track of the websites computers in your house are visiting. This all happens transparently, without having to install any software on your computers, iPods or iPads.

The easiest way to protect  all the computers and internet devices in hour home is to manually change the DNS servers that your internet router uses to the two OpenDNS servers. If you want to change your DNS settings now just use the following:

• 208.67.222.222
• 208.67.220.220

If you need help figuring out where to change the DNS settings for your router, OpenDNS has a great tutorial that shows you how on their website.

OpenDNS along with Dropbox and two services that every home should seriously consider using. OpenDNS is completely free, and Dropbox is free up to 2GB of data backed up. Enjoy!
