What is a domain?
A domain name is the address of a website like this: www.mysite.com. A domain is like the mailing address for the location of a residence. If you have the address of a residence, you know how to get to the location; if you have the domain name, you know how to get to the website. These are the different parts of a domain name:
| com | — | this is the Top Level Domain (TLD) | |
| mysite | — | this is the second level domain or subdomain of .com; this is often loosely referred to as the domain. | |
| www | — | this is the subdomain of mysite; if set up correctly, it is not necessary to have the www to get to the website. |
There are different kinds of TLDs:
- Generic: .biz .com .edu .info .name .net .org .pro
- Sponsored: .aero .asia .cat .coop .edu .gov .int .jobs .mil .mobi .museum .tel .travel
- Country-codes: .au (Australia) .ca (Canada) .ie (Ireland) .nz (New Zealand) .uk (United Kindgom) .us (United States) .za (South Africa)
You can find the authoritative list of current TLDs at the IANA website.
