You might have asked silently within you countless times, What is even a Domain Name?


Domain Names are simply the familiar, easy-to remember and always unique names that identify the internet resource such as website, an identification of a sequence of characters or some variables of administrative autonomy, authority or control on the internet. Domain Names are formed by the rules of the Domain Name System (DNS), a hierarchical distributed naming system for computers, services, or any resource connected to the internet or a private network.


Domain names are used in various networking contexts and application-specific naming and addressing purposes. In general a domain name represents an internet protocol (IP) resource such as personal computers used to access the internet, a server computer hosting a website or the website itself or any other service communicating via the internet. DNS simply translates domain names into the numeric IP address because humans find it difficult to remember.



Technically speaking a domain name is a hierarchical series of character strings representing different levels of domains separated by dots (periods) proceeding from the top level domains at the right end of the name to specific host names to the left. The individual words between the dots are called labels

The label furthest right represents the top-level domain.

There are two types of top-level domains; generic and country code;


The generic top-level domains are created for use by the internet public e.g. .com, .edu, .org, .gov, .info, .net etc

While the country code top-level are two letter domain names which correspond to a country, territory or other geographical location e.g .uk, .de, .ng, .us


Subdomains: A domain is said to be a subdomain of another domain if it is contained within that domain. e.g. http://voice.cloudsms.com.ng/ where voice is a subdomain of cloudsms.

A fully qualified domain name (FQDN) is a domain name that extends all the way back to root. E.g. http://voice.cloudsms.com.ng/

Some Providers also provide and register Domain Names

The Internet Corporation for Assigned Names and Numbers (ICANN) is the ultimate authority for domain name assignments.
