What is Google DNS
Google DNS (Domain Name System) is a public DNS service provided by Google that can be used to resolve domain names to IP addresses on the internet. DNS is the system that translates human-readable domain names (such as www.google.com) into IP addresses (such as 184.108.40.206) that computers use to communicate with each other.
Google Public DNS represents two servers with IP addresses for IPv4 – 220.127.116.11 and 18.104.22.168. 22.214.171.124 is the primary DNS, 126.96.36.199 is the secondary one.
Google DNS service is free to use and can be used by anyone who has access to the Internet. You can use Google servers IP addresses as alternate DNS instead of such provided by your ISP with the purpose to resolve Internet names faster and improve your security.
You can configure Google DNS on individual devices or on your router, which will apply the settings to all devices on your network.
