Technology Internet Parental Controls

Tuesday, February 21, 2012

I am sometimes asked how to block inappropriate content from home and business networks. There is complex software that can be installed on every computer, but the simplest, most flexible, and complete solution is to block inappropriate web sites at the time their internal addresses are retrieved, a process called DNS lookup. This method filters all Internet devices on the network, and cannot be easily disabled.

OpenDNS has a service that blocks inappropriate content by making its own DNS service be used for all network lookups. It is enabled by logging into the network router and changing the DNS settings to point to their IP addresses. Once you do that, you have the ability to block access based on 56 criteria.

The service is free, but there is also a premium service for USD $20/year. Because most homes and small businesses are assigned dynamic IP address that change occasionally, it is suggested that you install a program on one of your computers so that when your IP address changes, OpenDNS will be informed so you can always access your administrative console.

I just finished watching the television series Coal (trailer, review) on Netflix. The series gives an accurate feeling for the hard life of coal mining, including the claustrophobia.
