How Does DNS Work? Learn about SafeServe, Namecheap’s Free Private Domain Name System
Have you ever wondered how the internet works? How is it that you can type a website address into your browser and instantly be connected to that website? The answer lies in the Domain Name System (DNS), a fundamental technology that allows us to navigate the internet with ease. In this article, we’ll explore how DNS works and introduce you to SafeServe, Namecheap’s free private DNS service.
What is DNS?
DNS, or the Domain Name System, is like the phone book of the internet. It translates domain names, such as www.example.com, into IP addresses, which are unique numerical identifiers that computers use to communicate with each other. Without DNS, we would have to remember and type in long strings of numbers to access websites, which would be incredibly inconvenient.
When you enter a domain name into your browser, your computer contacts a DNS resolver, which is typically provided by your internet service provider (ISP). The resolver then looks up the IP address associated with that domain name in a DNS server. Once the IP address is found, your computer can establish a connection with the website’s server and retrieve the requested webpage.
The DNS Hierarchy
DNS operates in a hierarchical structure, with multiple levels of DNS servers. At the top of the hierarchy are the root servers, which are responsible for directing queries to the appropriate top-level domain (TLD) servers. TLD servers are responsible for handling queries for specific domain extensions, such as .com, .org, or .net.
Below the TLD servers are authoritative DNS servers, which hold the actual DNS records for individual domain names. These records contain information such as the IP address of the website’s server and other DNS settings. When a resolver queries an authoritative DNS server, it receives the necessary information to connect to the requested website.
