What is the definition of domain name?

Answer 1

What is a domain name? Loosely speaking a web domain is a means of

identifying or addressing a particular device on a network. More

importantly, a domain name can be used as a means of identifying a

brand or ownership of a particular website or resource on the internet.

No-one ever really 'owns' a domain, but registering one gives you the

exclusive right to its use for the period you have registered it for.

Saying someone is the 'domain owner' is usually more readily understood

than calling them the 'domain registrant' which is more correct.

As all domain names are unique, having your own domain name means that

you can easily tell people how to find your own piece of the internet

pie and at the same time allow them access to it. Simply type in your

domain name into a web browser and your website should appear to be

viewed.

Domain names can be 'owned' by an individual or company for a

particular period of time depending on how many years the person or

company has registered it for. Should the domain name registration not

be renewed, then its registration lapses and the domain name becomes

available for someone else to register it and 'own' it and put it to

their own use.

So really then, what is a domain name? All websites and servers on the

internet actually have an internet protocol address or IP address so

that they can be found. This is in the form of 4 groups of numbers

nnn.nnn.nnn.nnn (for IPv4 addresses). The trouble is, as humans, these

IP addresses are reasonably hard to remember and can easily be

mIstyPPed or forgotten. What if there was an easier way to remember

these IP addresses? That is where the domain name comes in. As every

domain name is unique and every IP address is unique to a device or

server on the internet, we can easily point a domain name to an IP

address, so you no longer have to remember the IP address, just the

domain name. Better yet, say you move your website from one web server

with an IP address to a different web server with a different IP

address? No, problem, just point your domain name to the new IP

address, and your website at its new location can be found instantly

using the same domain name.

What is a domain name made up of? A domain name is made up of various

levels and you tend to read them going right to left (and not left to

right as you normally would). Take for instance www.mydomain.com ...

the 'com' part is the top or first level part and consists of 'com',

'net', org', 'gov', 'info' etc or other country identifiers like 'UK'

or 'nz'. You would think that these top level ones for countries would

be pretty stable wouldn't you, but they are not. Certain countries

break into 2 or more countries (eg. 'Czechoslovakia' into 'Czech

Republic' and 'Slovakia') and so that neither has the original top

level domain advantage, the original gets retired and taken out of use

for a period of 50 years.

You can also get creative by using a top level identifier for something

other than what it was intended for. Even though '.de' is the top level

domain qualifier for German websites, if you registered 'tra.de' you

could form the word 'trade' in English which is a clever way to get a

memorable and short domain name. The next part of the domain name is

the second level and third level which are the ones that you can be

imaginative and make up something yourself to register. Not all second

level domain names can be registered as they are dependent on the

country (like '.co.UK' or '.co.nz'), but for others as in the example

above 'mydomain.com' you can register it (if available).

Should you register yourself a domain name? Why not? Domain names are

going fast, they are very affordable and easy to register, and even

though you may not have a need for one today, you may like to have the

peace of mind that one day in the future when you may need one, you

already have a good one tucked away. Good domain names are also worth a

bit of money, so if you can register a 'good' one, perhaps it will be

worth holding onto it for an investment!

So what is a domain name? It is all of the above and more .
