What Is the DNS Server for CenturyLink?

The Domain Name System (DNS) is a crucial component of the internet that translates human-readable domain names into IP addresses, allowing computers to communicate with each other. Each internet service provider (ISP) typically has its own DNS server, and CenturyLink is no exception.

A DNS server functions as a directory for the internet, translating domain names into IP addresses. When you enter a website’s URL into your browser, your device sends a request to a DNS server to find the corresponding IP address. This process is known as DNS resolution.
