A List Of Free Public Domain Name Services (DNS)

A domain name service (DNS) translates a human-friendly Internet address such as “yahoo.com” into an IP address, such as “98.139.183.24″.

DNS blocking is often used to censor web sites because it relatively easily to implement. However, it is also easy to avoid. For example, you can use one of the public servers listed below. Here’s how to change your DNS:

  • Windows users will need to go into their network device’s properties, then go into the IPv4 properties, and then change the DNS servers in the bottom section of the window.
  • Mac OS X users will need to go into their System Preferences, click on “Network“, choose their network device, click on “Advanced”, and then enter DNS servers after clicking on the DNS tab.
  • Linux users will need to click on their network applet, choose Edit Connections, click on “Edit” for your network device, and under the “IPv4 Settings” tab, choose the “Automatic (DHCP) addresses only” profile, and then add the DNS servers into the DNS servers textbox, with each server address separated by a comma.
