An Overview of Domain Names

A domain name is a method of identifying internet websites designed to help people tell the difference between sites on the internet or world wide web. Domain names are used in various networking contexts and application-specific naming and addressing purposes.

The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains, such as the .com, .net and .org, and the country code top-level domains (ccTLDs).

Below the top-level domains are the second-level and third-level domain names that can be reserved end-users that wish to connect local area networks to the Internet, run websites, or create other publicly accessible Internet resources.

The registration of domain names is usually administered by domain name registrars who sell their services to the public. Individual Internet host computers use domain names as host identifiers, or hostnames. Hostnames are labels in the domain name system usually without further subordinate domain name space.

Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites (e.g.,

An important purpose of domain names is to provide easily recognizable names to numerically addressed Internet resources.

What is multiple domain hosting?

Multiple domain hosting is offered by many web hosting companies. Under most hosting plans, users an host multiple domains under the same hosting account. There is no need to have a separate hosting account for each domain name.

What is Domain Parking?

If you are planning to build up a website and have decided on a name for it you then must purchase that a name from a registrar: i.e. your internet name gets placed on a name server so that you can use it later on. This is known as domain parking.

Even if your website content is not ready, it’s better to park your desired name.  Otherwise, it might be possible that in future somebody else acquires that particular web location.

What are sub domains?

Sub-domains are ‘third level’ websites in the sense that they are used solely to organize your website content. They are simply folders under your root directory, but to access them a special URL is used.  For example, is a regular URL without a sub-domain.  is a URL with the sub-domain name: “features”.

Generally when you register an address it is registered for a minimum of one year. However, you can register it for more years, as there is no hard and fast rule as such.

What is Domain Renewal?

After one year you need to renew your internet name so that your website doesn’t get lost. Generally when your domain is about to expire your registrar will send you a reminder mail regarding the renewal.

What happens when your name expires?

When your web name expires you can renew it within one month. If you don’t renew it in this period it goes into a redemption phase. It stays in this redemption phase for 15 to 30 days before it is then available for purchase again at a normal price. Getting an address out of redemption phase is like buying fifty as it can cost around $200.

What is a WhoIs record?

WhoIS record is a domain name search engine/Internet program where users can enter an Internet entity (e.g., a network, some hosts) and it will give detailed information on the registrar, the owner, and respective DNS records.
