Domain and hosting

WHAT’S A DOMAIN?

A web 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 (e.g a web site), or may be a private intranet.

A web 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.

WHAT ARE THE DIFFERENT TYPES OF DOMAIN NAMES?

TLD – Top Level Domains

These are at the highest level in the DNS structure of the Internet. There are several different types of TLD’s, being:

ccTLD – country code Top Level Domains

Two letter domains established for geographical locations; for example; .au signifies Australia. When originally designated, usually only residents of a country could register their corresponding ccTLD; but over the years quite a few countries have allowed parties outside their shores to register website names. An example of this is Tuvalu (.tv).

For example, .com.au registrants must still be Australians or have registered business interests in Australia. The registration eligibility criteria for au names has meant .au is still strongly associated with Australia and has fostered a great deal of trust and confidence in local and even overseas online shoppers.

gTLD – generic Top Level Domain

The best known generic TLD’s include .com, .net, .biz, .org and .info – these can be registered by anyone, anywhere in the world. However, some of the new gTLD’s more recently released have various restrictions.

IDN ccTLD – internationalised country code top-level domains

A top-level name with a specially encoded format that allows it to be displayed in a non-Latin character set (i.e. special characters).


Subdomain

Part of a higher ranked domain name in DNS hierarchy; e.g. example.domainregistration.com.au.

Some services offer subdomain “registration” – but this usually isn’t ideal for businesses and should probably be avoided for establishing a commercial website as the registrant of the upper hierarchy name has control over the address. Having your own name can also help with credibility.

As mentioned, understanding the differences between the above really isn’t all that important – but something you will need to know is how to register a domain name. It’s also a good idea to pick up some tips on choosing domains before you start your search and registration process.


CURIOSITY ABOUT DOMAIN

The first Internet domain name “symbolics.com” was registerd by Symbolics, a Massachusetts Computer Company on March 15, 1985.

Domain names are used to identify one or more IP adress.

WHAT’S HOSTING?

A web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet. A web host or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed in the Internet.

THE DIFFERENCE BETWEEN A DOMAIN NAME AND A WEB HOSTING

Imagine a house. The structure of the house would be equivalent to Hosting. The house has furniture, these correspond to the “Data Files”. The house is located somewhere, so, it has an address that is equivalent to the “Domain Name”.
