Everyone knows .COM, the unrestricted domain extension for companies or commercial enterprises that is the most recognized TLD (top level domain) on the web. Most people in our country also recognize .CA, the ccTLD (country code Top Level Domain) that represents Canada.
But what about all the other domain extensions out there? .ORG, .NET, .MOBI, .TV, .TEL, .BIZ…, in fact there are over 280 different domain extensions delegated globally. What do they all mean and what’s their relative importance to Canadian small businesses? It’s important that a small business understand what its options are for developing and marketing their brand in the online arena.
According to the latest Domain Name Industry Brief (published by VeriSign), the first quarter of 2010 ended with more than 193 million domain names registered worldwide, an increase of 11 million registrations or 6% from 2009.
The following are the most popular domain extensions in the world ranked by number of total registrations (1st Quarter 2010) - Source: VeriSign Domain Name Industry Brief

According to data from Zooknic, Canada’s .CA ranks #15 as of March 31, 2010.
Domain names are divided into 2 main categories, gTLDs or “generic top-level domains” (some of which are sponsored by designated agencies and some are restricted by types of registrants) and ccTLDs or “country code top level domains" which represent a country designation.
There are currently 20 gTLDs (generic top-level domains) in the world. The following shows what each represents:
- .aero (the air-transport industry),
- .asia (Asian Pacific Region)
- .biz (businesses but all uses),
- .cat (Catalan linguistic & cultural community)
- .com (commerce but unrestricted/all uses)
- .coop (cooperatives),
- .edu (post-secondary educational institutions)
- .gov (government of US)
- .info (informational sites but unrestricted/all uses),
- .int (international organizations established by treaty)
- .jobs (employment-related sites)
- .mil (US military)
- .mobi (mobile uses)
- .museum (museums),
- .name (individuals),
- .net (networks but unrestricuted/all uses)
- .org (organizations but unrestricted/all uses)
- .pro (professions like legal, medical)

In 2008/2009, ICANN (Internet Corporation for Assigned Names & Numbers) started a new TLD naming policy to take a "significant step forward on the introduction of new generic top-level domains." It is expected that the new rules could result in hundreds of new gTLDs to be approved.
