By default, your Chromebook will be using your ISP’s DNS servers to connect with the internet out there. There are plenty of other DNS services available online, such an OpenDNS or Google Public DNS.

They can also help you block ads on Chromebooks or other undesirable content.

Why Should You Change DNS on Chromebook

Your computer performs several DNS lookups every day, depending on how many websites you visit. Some web pages require multiple DNS lookups. This is your computer essentially trying to find the domain name you have typed in the address field. So a DNS server is what serves those domain names to your computer. A server that can do it faster will allow your computer to open websites faster.
