How To Use The Google Public DNS.

Google Public DNS is both free to use and secure. Switching your DNS (Domain Name System) server to Google’s is straightforward on your home computer; and if you don’t see any improvement, you can always change back again.

Most of us, on our home computers, will be using the DNS servers setup by our ISP (Internet Service Provider).

Whilst there isn’t anything wrong with that, you have to accept that ISP servers vary considerably in the time required to resolve any given query. Some are very good and, obviously, some aren’t.

The Internet Protocol Version 4 (TCP/IPv4) box is split into 2 sections. The top section refers to your computer’s IP address and default gateway (router). Leave this section as it is.

The lower section details the IP address of the DNS server that your computer should be using. Generally, it’ll be set to “Obtain DNS server address automatically” and both the boxes will be empty (blank).

On your computer, if the “Use the following DNS server address” option is selected and you can see IP addresses in the boxes, then make a quick note of those address numbers.

Switching away from your ISP-provided DNS server to Google’s servers isn’t a guarantee of better Internet performance. In fact, things could get worse. It all depends on what you’ve got right now.
By keeping a note of the current DNS server IP addresses, you can always change back if things don’t work out for the better.
