List of Domain Name Suffixes

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. They are organized in subordinate levels (sub-domains) of the DNS root domain as you cab see below in the List of Domain Name Suffixes.

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 are typically open for reservation by end-users that wish to connect local area networks to the Internet, run websites, or create other publicly accessible Internet resources. The registration of these 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.,

Domain names are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the realm identifiers used in the Session Initiation Protocol (SIP), the DomainKeys used to verify DNS domains in e-mail systems, and in many other Uniform Resource Identifiers (URI).

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

Domain names are often referred to simply as domains. Domain name registration with a registrar does not confer any legal ownership of the domain name, only an exclusive right of use.

Resources Looking Up Domain Names

The following are resources for looking up and verifying domain names, determining ownership, etc. These sites are offered both for those who are interested in registering their site, and for detectives who need to conduct research into the ownership of a particular website.

List of Domain Name Suffixes

Domain name suffixes are the extensions found at the end of a website address (URL) or e-mail address that signify the category of a particular web site. The list of extensions is constantly growing. The information may be helpful in conducting investigations related to website hacking, identity theft and online bullying.

More Information On Website Domain Names

It’s been two years since John started his online business. He is very much satisfied with his current web host whose services he acquired one year ago. Today John is relaxing in his chair and thinking about the initial days when he spent many hours on the Internet collecting information related to web hosting. Like him there are many John’s out there who are in search of information everyday, visiting this and that website hoping to find the most illuminating advice.

The problem is that common topics of interest can be found on most of the websites whereas other relevant issues are not dealt with everywhere.

What is multiple domain hosting?

Many times you will see that a web host offers multiple domain hosting. In simpler words it means that on buying an account you will have the ability to get multiple websites. For instance, if the plan provides you with five website names, you can use one for your website and you will still have four website addresses leftover to use. The advantage of this scenario is that you can resell these four names to your clients.

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.

How to find out the owner of a internet name?

To find out the owner, use the WhoIs search tool on the Internet .For E.g. Go to and type the domain address under Dossier. It will show you the title of the registrant / domain’s owner / web host.

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.
