DNS

Web address translator

DNS stands for Domain Name System, the internet's method of translating human-readable website addresses into numerical IP addresses that computers use to locate each other.

When you type a URL into your browser, DNS servers look up the corresponding numbers: The site won't load—it might be a DNS issue.

DNS functions like a phone book for the internet, matching names to addresses behind the scenes.
