.co (second-level domain)

Last updated

In a number of countries, .co (an abbreviation of commercial) is used as a second-level domain in the Domain Name System used to route internet traffic. Domain registrants register second-level domains of the form .co.xx, where xx is the country code top level domain (e.g., .co.uk in the U.K. and .co.jp in Japan).

Countries using .co as a second-level domain include: Barbados (.bb), Cook Islands (.ck), Costa Rica (.cr), India (.in), Indonesia (.id), Israel (.il), Japan (.jp), New Zealand (.nz), South Africa (.za), South Korea (.kr), Thailand (.th), United Kingdom (.uk) and Venezuela (.ve).

.co is also a country top-level domain corresponding to Colombia. Its current manager, Neustar, markets it globally as an alternative to .com. [1]

The Domain Name System of the Internet consists of a set of top-level domains that constitute the root domain of the hierarchical name space and database. In the growth of the Internet, it became desirable to expand the initial set of six generic top-level domains in 1984.
