A domain name is the unique name for a website. For example, the domain name of Eltoma IT Services is “Eltoma-it.com”. Domain names work as an online address, which is used to access a websites. It’s what visitors will use to find you online and is a fundamental aspect of any website. When you register your domain name, it becomes unique and nobody else can register the same name. If you stop renewing your domain then somebody else can register the same name.
How domains work
When you access a website, the domain name is translated to an IP Address, which defines the server where the website is located. This translation is performed by service called DNS (Domain Name System). The Domain Name Server (DNS) is a decentralised naming system for computers, devices, or any resource connected to the Internet or a private network.
Are URLs & domains the same thing?
They are different. A URL is something called a Uniform Resource Locator, which is a set of directions containing detailed information. A domain name makes up part of a URL and makes it easy to recognise the entire address.
Eltoma Web Services URL would be: https://www.eltoma-it.com/services/website-creation
It contains “hypertext transfer protocol” (HTTP) which effectively tells the browser the domain name instead of an IP address. Next is the subdomain WWW which stands for “World Wide Web”. This is used to distinguish the type of content, after that there is the main domain name of our website which points to the server where the website is hosted and the files on that server. Finally there are directories and a web page at the end.
Emails & Domains
When you have registered your domain name it’s easy to setup your own email addresses with your name of choice, for instance: email@example.com. It has a lot of advantages for professional communication. It’s useful to register your domain name, so you can have a unique email address instead of using Gmail, Yahoo or Hotmail for example.
Top-level & second-level domain names
A top-level domain (TLD) is when a domain is at the highest level in the domain name system. For example, in the domain name www.eltoma-it.com, the top-level domain is com. These types of domains only contain one suffix: .com, .net, .info.
Second-level domain (2LD) are domains containing one more level suffixes after .com. For example, .com.ru is a second level domain containing an additional suffix, which shows us that this domain is based in Russia.
