OpenDNS is a wonderful (and free) service which can be used to regulate Internet access and restrict viewing of certain types of sites.
One of the fundamental services on the Internet is the Domain Name Service, or DNS. DNS is used to translate symbolic names such as www.google.com to numeric IP addresses such as 22.214.171.124.
OpenDNS provides a free DNS service, with the ability to restrict resolution of certain types of sites, such as adult oriented content, gambling, alcohol, hate crimes, etc.
