Frequently Asked Questions

What is a domain name?

A domain name is the address of your website, it’s what people type in a web browser to access your website online. As each domain is unique, it serves as the identity of a person, business or organisation on the Internet. Domains are also used for transmitting and receiving data, files, and emails and for running web applications. As a domain represents a person, brand or business on the internet, it may very well be the most valuable asset you’ll own. Imagine what value holds for Google. There you go.

What is a domain name extension?

As soon as you register or transfer a domain, you can create a hosting server and start creating your website with WordPress or any other CMS of your choice. What’s more, you can also opt for stand alone drag & drop website builders.

Every domain name comprises of two parts. For example, our domain name is ‘’, the first part is our brand name ‘rocket’ and the second part is the extension ‘domains’. An extension, therefore, is the last part or ending of your domain name and is also known as the ‘TLD’ (Top-Level Domain) or the domain root. Some of the most popular TLDs include .com, .net, .online,, .org.

There are hundreds of other extensions such as ccTLDs and the new gTLDs. ccTLDs stand for “Country Code TLDs” as they denote a specific country, for example .us for the USA, for the UK and for Australia.

The ICANN has introduced new gTLDs which are more memorable and meaningful, for example, .online, .site, .blog, .lawyer, .dentist, .accountant, .property etc. 

It’s advisable to register your domain name in as many extensions as possible to ensure your brand name remains fully protected against cybersquatting.

What is DNS?

DNS stands for the Domain Name System which is the address-book of the Internet. Prior to domain names, web addresses were made up of a string of numbers called IP (Internet Protocol) addresses which in turn identified the computers hosting webpages on the Internet.  These IP addresses were hard to remember and presented great difficulty for humans to access websites online.

The Domain Name System offered a solution to this problem as follows:

✧ The domain Names could be made up of simple words which were easier for people to memorise and relate to;
✧ The domain Names could be pointed to the unique IP addresses of the computer that hosted a website;
✧ People could therefore access a website by simply typing a Domain Name in a Web browser.

Thanks to the DNS System, humans were able to easily access information online through domain names, like, or

How long can I register a domain name for?
