Is DNS Server Same as IP Address?

When it comes to understanding the intricacies of the internet, it’s important to grasp the concepts of DNS servers and IP addresses. While they are related, they serve different purposes in the world of networking.

The Basics: IP Address

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a network. It serves as an identifier, allowing devices to communicate with each other over the internet. An IP address consists of four sets of numbers, separated by periods, such as

For example, when you type a website’s URL into your browser’s address bar and hit enter, your computer contacts a DNS server to translate that URL into an IP address. This IP address is then used to establish a connection with the website’s server.

The Role of DNS Servers

DNS (Domain Name System) servers play a crucial role in translating human-readable domain names into machine-readable IP addresses. The internet relies on this system to function smoothly.

When you enter a URL like “” into your browser, your computer sends a request to a DNS server asking for the corresponding IP address associated with that domain name. The DNS server then searches its databases for the requested information and returns the IP address back to your computer.

DNS Resolvers

A DNS resolver is responsible for initiating and handling the process of translating domain names into IP addresses. It acts as an intermediary between your computer and the DNS server.

  • Recursive Resolvers: These resolvers perform all the necessary steps required to obtain the final result from other DNS servers if they don’t have the requested information in their cache.
  • Iterative Resolvers: These resolvers perform the same steps as recursive resolvers, but instead of obtaining the final result, they return a referral to another DNS server that may have the requested information.


In summary, while DNS servers and IP addresses are closely related in their functionality, they serve different purposes. An IP address is a unique identifier assigned to devices on a network. On the other hand, DNS servers are responsible for translating domain names into IP addresses, allowing us to access websites using human-readable URLs.

Understanding these concepts is important for anyone interested in how the internet works. So next time you browse the web, remember that your computer relies on both DNS servers and IP addresses to establish connections and retrieve information.
