What Is Level 3 DNS Server?
When it comes to browsing the internet, we often take for granted the complex processes that happen behind the scenes to ensure that we are directed to the correct websites. One critical component of this process is the Domain Name System (DNS), which acts as a translator between human-readable domain names and IP addresses. In this article, we will focus on Level 3 DNS servers and explore their significance in the overall functioning of the internet.
The Basics of DNS
Before diving into Level 3 DNS servers, let’s briefly understand how DNS works in general. When you type a URL into your web browser, such as www.example.com, your computer needs to obtain the corresponding IP address associated with that domain name. This is where DNS comes into play.
DNS servers maintain a distributed database that stores information about domain names and their associated IP addresses. When you enter a URL, your computer sends a query to a DNS server, requesting the IP address for that domain name. The DNS server responds with the correct IP address, allowing your browser to establish a connection with the desired website.

The Transition to CenturyLink
In November 2017, CenturyLink completed its acquisition of Level 3 Communications. As a result, the Level 3 DNS servers became part of CenturyLink’s broader infrastructure.
CenturyLink continues to provide reliable DNS services to its customers, leveraging the expertise gained from Level 3’s robust network. The integration has allowed CenturyLink to enhance its global reach and deliver exceptional performance to users worldwide.
The Level 3 DNS servers played a pivotal role in providing fast and reliable DNS resolution for internet users. With their extensive network infrastructure and distributed architecture, they offered enhanced performance and global reach. Although they are now part of CenturyLink, their legacy lives on in the form of improved internet connectivity for millions of people around the world.
