What is DNS?

DNS is like an address, where the domain name is trying to get to the account that has the website files in it. The nameservers are the town name, and the A record is the street address of the server. If you want to figure out where a domain is pointed (in other words, figure out what its DNS is doing) is to follow a few simple rules. Let’s take a walk through an example using tsuk2.com. 

When you type tsuk2.com into a browser, the first thing that happens (as far as we are concerned) is that the browser looks at the nameservers for the domain. It would see the following. 

dns1.uk2.net
dns2.uk2.net
dns3.uk2.net

The browser then says “Ah, the DNS information is stored at UK2.” The browser then comes to our nameservers, and says “Where is the content for this site, tsuk2.com?” Our nameservers have on them an A record which says this: 

tsuk2.com points to 176.67.160.8

So from here,  the browser goes to the server that is assigned this IP address and says “I hear you have the content for this website…” the server says back “Yes, I do. Here are the files.” and then the browser takes those files and displays them on your computer.
