Use Hosts File for Personal DNS Management

If you don’t have the ability to update DNS entries on you network but still need to associate or (dis-associate) a name to (from) an IP number you can use your HOSTS file located in C:\Windows\System32\drivers\etc. The # is used to comment       localhost       MyDevSharePointServer.MyDomain.Com       MyTestServer

Use shortcuts to go to your favorite websites:       f       # Fark       g      # Google

You can also block unwanted domain names from resolving by pointing them back to your local IP –       IHateThisWebSite.Com       # Never take me there again       NastyWebSite.Com       # Ewww!
