Recently, I started using a new service called OpenDNS. OpenDNS is primarily a Domain Naming System service. (DNS is how your computer knows how to find something like www.yahoo.com.) On top of this service, they provide Internet filtering that you can configure from their web site. The service is free and is supported by adds that appear when you use their search engine or a website is blocked.
Some of their main features are as follows:
Adult Site Blocking
I've been using it for about 1 month and like the service so far. It covers my entire home network just by configuring my DHCP router to use the OpenDNS servers instead of my ISP's. I encourage you to check it out. If you have questions or want assistance setting it up, please feel free to contact me at firstname.lastname@example.org.
