DNS Flush

As a general rule, every time the hosts file is modified, it is recommended that you flush your DNS so that the new changes can be implemented more swiftly.

On most OS, rebooting the computer is the easiest way. However, DNS flushing can also be done manually using command line:

ipconfig /flushdns
