What is DNS?

What is DNS? FixRunner.com explains what Domain Name System means and what it does for your WordPress website.

DNS is a hard concept to explain, but a very simple protocol to use. It is the behind-the-scenes function that allows the information on your website to be connected to your domain name (your website address) and therefore serves a vital function. DNS settings on this blog are enabling you to see this article and find it by typing the WordPress-run FixRunner blog URL into the search bar!
Let’s look at some of the basics first:

What is DNS?

DNS stands for Domain Name System. It is a protocol that allows computers to exchange data on the internet and within private networks, also known as the TCP/IP protocol.

How does it work?

Think of DNS as internet GPS, that helps point computers to servers, information and destinations. It’s most basic and common function is to turn a regular domain name like FixRunner.com into an IP address or set of numbers like 100.20.300.40 so that computers can recognize each other on their networks.
When you type in www.FixRunner.com into your browser’s search bar, your computer will be using a numerical IP address to route this request to the site you are looking to view. A good analog is when you type “Mom” or “Dad” into your smartphone – the memory is calling up the telephone number associated with that name, which you may or may not remember. DNS means that you do not have to remember all the IP addresses of every website that you want to visit! Instead of doing that, DNS servers or nameservers route you through to their databases which map domain names to IP addresses and eventually show you the content that belong to the domain address you are trying to view.

How do I know my nameserver details?

As a domain owner with a WordPress blog or WordPress business website, you will have been given domain nameservers by your hosting company. From the moment you purchase a domain, the hosting company you have selected will provide you with the nameserver details. For example, if your host is HostGator, your nameserver details may be something like this:
Nameserver 1: ns.hostgator.com
Nameserver 2: ns2.hostgator.com

I forgot to write this information down. How can I get it again?

Don’t worry – the process of purchasing a domain, hosting account and getting a website up and running involves a lot of stages, some of which it can be hard to remember. You can always contact us and enjoy our free website setup service.
