What the hell is a domain name, anyway?

A domain name is simply a name ending with a TLD. TLD stands for Top Level Domain. Some examples:

stevejamesson.com
irs.gov
google.com
abtech.edu
cakephp.org

The TLD is the .com, .org, .net, etc. portion of the domain name.

Domain registrars

In order to have a website, you’re gonna need a domain name. You can register a domain name with a whole bunch of different registrars. A registrar is simply a company that’s authorized to register domain names. There are many registrars, including these popular ones.

There are of course many other sites that will offer to register a domain name for you.

How much is it?

The general cost of a domain name is typically no more than about $20 per year, so if you’re currently paying more than that, then you might want to consider transferring your domain name to a different registrar to save some money.

Think alias

A domain name is kinda like an alias. Think of it as speed dial on your phone. Behind every domain name is what’s called an A Record. An A Record points a domain name at an IP address. An IP address is kind of like a phone number, except it’s for computers.

So when you use speed dial number 3, you call a phone number like (111) 222-3333. Well the same thing kinda happens whenever you type in google.com or another domain name.

  1. Your web browser looks up the domain name via a name server, generally provided by your Internet Service Provider (ISP)
  2. The name server tells your web browser that it points to some IP address (i.e. 11.22.33.44)
  3. The computer located at that IP address takes it from there, and you’re shown a website

So it’s kinda like a speed dial. The technology of how all this stuff works is pretty heavy, so I won’t go into those details here.

Is that it?

Yeah, that’s pretty much it. To summarize:

  • A domain name is simply a name with a .com, .net, .org or other TLD.
  • Behind a domain name is an A Record, which points the domain name to an IP Address, which is a numeric address for one computer.
  • That computer takes over from here, showing you a website
