Chicago (IL) – An organization called IANA (Internet Assigned Numbers Authority) publishes a root zone database, which lists all top-level domains, such as .com, .org and .net. TGdaily has compiled this list into a reference chart which describes each domain, or its country of association. Typically commercial uses in other countries will be prefixed with “.com” or “.co”, as in “.co.uk” being a .com-like address for the United Kingdom. However, sometimes they go simply with their country’s extension, as in Coca-Cola Canada (www.cocacola.ca).
There are 244 country codes, as well as 11 test domains that are not used for any purposes other than testing and are excluded from this list. The sponsored domains are reserved for use by their associated agencies only, and as authorized by them. The ones listed as generic or generic-sponsored are generally available for use by anybody who chooses to register a domain.
Any person or company can register a domain on the common domain extensions, such as .com, .net, .org, etc. A domain registration typically requires hosting for the website, and prices begin around $5.95 per month (less some places, considerably more others) and generally go up from there depending on bandwidth requirements, storage requirements, and other commodity-related specifics.
