DNS Masquerading


What is the purpose of DNS Masquerading and why would someone implement or use it?

In: Technology

Two main reasons, one is you can insert your own rules, useful to make specific domains point to internal locations, especially to make local computer names available via DNS for the whole network.

And two is caching. It will save the IP for google.com and provide it to all on the network, reducing upstream traffic (which your ISP might limit) and generally making DNS faster (which matters quite a bit on high latency networks, sattelite internet basically requires this to be useable).
