Register a domain name with Mainframe Internet

What is a domain?

A domain or URL (Uniform Resource Locator), for example, consists of three parts: sub domain, domain name, and tld (top level domain). A URL is a memorable and user-friendly address that is translated by DNS, or the Domain Name System.

DNS translates a domain or URL into the IP (Internet Protocol) address of the host server. When a URL is entered into your browser, the browser uses it to find the IP address it translates to, on which the website is hosted, and show the website.


The prefix to the domain name is the subdomain, this is an extension of your domain name that you can configure either to forward to URLs or point to a specific directory. i.e. can be pointed to


Your domain name is a unique address that that targets your website.

Multiple domain names can point to the same location.


This is the TLD or Top Level Domain.

There are two-letter ccTLDs (Country Code Top Level Domains) such as .uk for the United Kingdom and .nz for New Zealand, and then three or more letter gTLDs (Generic Top Level Domains) such as .com and .net. gTLDs also include geographic domains such as .london and industry-specific domains, .consulting for example.
