If you make you question clearer I could provide a better answer.

If you wish to create a local DNS on your system I would suggest you make alterations to your hosts file. Located at C:/Windows/System32/Drivers/etc in windows system.

The order in which DNS names are resolved is:

1. HOSTS configuration file
   
2. The DNS to which your computer is confugured

The HOSTS file has the highest priority so you could override the DNS server by configuring an IP in your HOSTS file.
