A domain name is a sequence of letters and/or numbers/hyphens separated by one or more periods (“.”) that act as a pointer to a unique numerical address (IP) on a computer network such as the Internet. That address may host publicly available content, or may be a private intranet. A domain name always ends with an extension of 2 or 3 characters. These characters can signify the country the website address is associated with or the type of organization; but this isn’t always the case – more on that below.
HOW DO DOMAIN NAMES WORK?
They operate under the Domain Name System (DNS), which is essentially the address book of the Internet that helps direct visitors to your website by translating the name into its related IP address number sequence and locating where the resource is stored. Learn more about how DNS works.
WHAT ARE THE DIFFERENT TYPES OF DOMAIN NAMES?
Thankfully, you don’t need to memorise all of the below as it can get a little confusing. As a registrant; usually all you need to be able to distinguish between is a domain name – the popular terms used collectively for second and third level domains – and a subdomain.
