What restrictions are there on what I can register as a domain name?

There are some basic rules that are enforced for domain names, focusing primarily on length, punctuation, and formatting.

These general rules are:

• Domains must use only letters, numbers, or hyphens (-).
• Domains cannot begin or end with a hyphen.
• .com, .net, .org, and .info domain names cannot exceed 67 characters in total.
• .info and .biz domain names must have at least 3 characters, not including .info or .biz.
• Some domain names cannot exceed 22 characters, not including the extension.
• Domain names are not case-sensitive.
• Domain names cannot include spaces.
• Two-letter domain names are no longer permitted.

Also, domain names should not begin with a number, but, in practice, this is possible in most circumstances.

You can use any combination of letters, words and phrases to create your domain name.
