Find out what your DNS is and learn how to check your DNS server easily using simple steps on any device. Quick and clear guide

Not just you, but many others are curious about "What is my DNS?" Though most people hardly consider DNS until something goes wrong, it is a vital component of the Internet. The contents of this article will teach you what DNS is, how it operates, and simple ways to view your DNS server.

What is DNS?

DNS is shortened from the Domain Name System. It functions similarly to an internet phone book.

If you type an address like www.google.com into your computer to launch a webpage, your computer must know this. DNS converts the website's name into an IP address your computer can understand—a figure like 142.250.190.4.

Remembering all the long numbers for every website would prove difficult without DNS.

What is a DNS Server?

An Internet machine designated for storing a list of domain names and IP addresses is a DNS server. Your device searches a DNS server for the IP address of a website when you attempt to visit one. The DNS server responds with the right number so your browser may load the webpage.

Usually set automatically by your internet service provider (ISP), your DNS server can be changed to run Google or Cloudflare.

Why Should You Check Your DNS Server?

There are several reasons to check your DNS:

  • Your internet may be slow, or websites may not load properly.
  • You might want to use a faster or more secure DNS provider.
