Edit the hosts file

The most common reason to edit the host file is to test a website before changing the ‘live DNS’ to complete a migration.  To do this, you should add lines as shown below:

x.x.x.x mydomain.com

x.x.x.x www.mydomain.com

Replace ‘x.x.x.x’ the IP address of your service with ourselves, and mydomain.com with the domain for which you wish to override the ‘live DNS’.

Remember to remove these lines once you have completed the testing and migrated!
