NOC Episode Open DNS

Do you have specific sites that you don't want to be able to access, or perhaps do not want your children to access?

Then Open DNS might be the cheap fast solution for you, and it does'nt get much cheaper than free!

Open DNS is a free service that categorizes numerous websites on the internet and can allow or deny access to those sites at the DNS level.

If you are not sure what a DNS is, it is like a big phone book for the internet. Every time you browse to a website a DNS request is made to find the IP address of the website's domain name. This would be the phone book equivalent of looking up John Smith, and finding his phone number so you can call him.

What's nice about Open DNS is that since everything is being categorized by the community, you can block out the types of sites you don't want. So when you look up badsite.com Open DNS will check if you want to allow it, and return the appropriate response.

Given this is not fool proof, and some sites will still get in, it is usefull to block a large majority of the sites.
