The obvious pro, is as long as we are using a good DNS server, we always know how to reach everything on the Internet. Step 3: Now that the host has a usable IP address, it directs it attention directly to that address. In very simplistic terms, DNS servers talk with other DNS servers and keep each other updated.

Not only does DNS filtering help protect users from accessing dangerous or unwanted domains, but it can significantly reduce the amount of unwanted traffic on your network. DNS filtering is an important part of a well planned firewall.
