Domain names by first four characters

International domain names (xn--)

International domain names are stored as punycode. There are presently 124,942 domain names stored with international domain name support.

Punycode, defined in RFC 3492, is the self-proclaimed "bootstring encoding" of Unicode strings into the limited character set supported by the Domain Name System. The encoding is used as part of IDNA, which is a system enabling the use of internationalized domain names in all languages that are supported by Unicode, where the burden of translation lies entirely with the user application (a web browser for example).

The encoding is applied separately to each component of a domain name which is not represented solely within the ASCII character set, and a reserved prefix 'xn--' is added to the translated Punycode string. For example, bücher becomes bcher-kva in Punycode, and therefore the domain name bücher.ch would be represented as xn--bcher-kva.ch in IDNA.

Generics

90,546 NET domain names contains the phrase "web" of which 14,234 consists of the phrase "webs", including KFWEBS.

35,836 domain names contains the phrase "host" and 15,654 NET domain names contains the phrase "hosting". As the NET top level domain is ordinarily used by infrastructure companies, domain registrars and hosters this doesn't strike as odd.

12,685 names contains "domain" and 1836 contains "register", whereby 38,166 contains the phrase "free".

The high occurence of domain names is as with the COM zone-file probably squatters, hoping that people will mis-type wwwcompany.net and get their advertisment instead of the actual site they intended going to.
