ccNSO is an acronym for The Country-Code Names Supporting Organization.

The purpose of the ccNSO is to engage and provide leadership in activities relevant to country-code top-level domains (ccTLDs). This is achieved by 1) Developing policy recommendations to the ICANN Board, 2) Nurturing consensus across the ccNSO’s community, including the name-related activities of ccTLDs; and 3) Coordinating with other ICANN SO’s, Committees, or constituencies under ICANN. The ccNSO selects one person to serve on the board.


A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.

In 2018, the Internet Assigned Numbers Authority (IANA) began implementing internationalized country code top-level domains, consisting of language-native characters when displayed in an end-user application. Creation and delegation of ccTLDs is described in RFC 1591, corresponding to ISO 3166-1 alpha-2 country codes. While gTLDs have to obey international regulations, ccTLDs are subjected to requirements that are determined by each country’s domain name regulation corporation. With over 150 million domain name registrations today, ccTLDs make up 40% of the total domain name industry. Country code extension applications began in 1985. The registered first extensions that year were .us (United States), .uk (United Kingdom), and .il (Israel). There are 312 ccTLDs in active use totally. .cn, .tk, .de and .uk contain the highest number of domains.


CVCV is an abbreviation for a consonant-vowel-consonant-vowel domain name.

C: consonant, defined as “(in English articulation) a speech sound produced by occluding with or without releasing (p, b; t, d; k, g), diverting (m, n, ng), or obstructing (f, v; s, z, etc.)”

V: vowel, defined as “a letter representing or usually representing a vowel, as, in English, a, e, i, o, u, and sometimes w and y.”

Not all letters are created equal. See the definition of Premium Letters in domain names for a list of which letters are more valuable.

CVCV refers to the domain itself and makes no specification as to the Top Level Domain (TLD), such as com or net.

There are total of 15,876 CVCV domain names available (21x6x21x6=15,876) if you count the letter Y as both a consonant and a vowel. If you consider only premium letter domain names, there are 6,084 CVCV domain names available (13x6x13x6=6,084).

Cybersquatting (also known as domain squatting), according to the United States federal law known as the Anticybersquatting Consumer Protection Act, is registering, trafficking in, or using a domain name with bad faith intent to profit from the goodwill of a trademark belonging to someone else. The cybersquatter then offers to sell the domain to the person or company who owns a trademark contained within the name at an inflated price.

Bad faith (Latin: mala fides) is a legal concept in which a malicious motive on the part of a party in a lawsuit undermines their case.
