A domain name registry is a database of all domain names and the associated registrant information in the top level domains of the Domain Name System (DNS) of the Internet that enables third party entities to request administrative control of a domain name. Most registries operate on the top-level and second-level of the DNS.
.ca is the Internet country code top-level domain (ccTLD) for Canada. The domain name registry that operates it is the Canadian Internet Registration Authority (CIRA).
.uk is the Internet country code top-level domain (ccTLD) for the United Kingdom. It was first registered in July 1985, seven months after the original generic top-level domains such as .com and the first country code after .us.
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.
.aq is the Internet country code top-level domain (ccTLD) for Antarctica. It is derived from the French Antarctique and is reserved for organizations that work in Antarctica or promote the Antarctic and Southern Ocean regions. It is administered by Peter Mott of Antarctica Network Information Centre Limited from Christchurch, New Zealand.
.jp is the Internet country code top-level domain (ccTLD) for Japan. It was established in 1986 and is administered by the Japan Registry Services.
.je is the country code top-level domain for Jersey. The domain is administered by Island Networks, who also administer the .gg domain for neighbouring territory Guernsey. In 2003, a Google Search website was made available for Jersey, which uses the .je domain.
.nz is the Internet country code top-level domain (ccTLD) for New Zealand. It is administered by InternetNZ, with oversight and dispute resolution handled by the Domain Name Commission Limited (DNCL). Registrations are processed via authorised registrars. As of September 2022 there were 750,200 registered .nz domains.

.in is the Internet country code top-level domain (ccTLD) for India. It was made available in 1989, four years after original generic top-level domains such as .com, .net and the country code like .us. It is currently administered by the National Internet Exchange of India (NIXI).
.it is the national top-level domain (ccTLD) assigned to Italy.
.gr is the country code top-level domain (ccTLD) for Greece. Registrations are processed via accredited registrars and domain names in Greek characters may also be registered.
.mp is the Internet country code top-level domain (ccTLD) for Northern Mariana Islands. There are a few sites related to the Northern Mariana Islands in this domain. The get.mp site allows users to register and manage .mp domains. The .mp name comes from ISO 3166 which specifies MP as the two letter designation for the Northern Mariana Islands.

.tj is the Internet country code top-level domain (ccTLD) for Tajikistan. Registrations are processed via accredited registrars.
.tz is the Internet country code top-level domain for Tanzania. Through a consultative process, Tanzania Network information Centre (tzNIC), a not-for-profit company was established and registered to administer and manage the operations of the Tanzania country code top-level domain. tzNIC is a limited company with two founding members – the Tanzania Communication Regulatory Authority and the Tanzania Internet Service Provider Association.
In the Domain Name System (DNS) hierarchy, a second-level domain is a domain that is directly below a top-level domain (TLD). For example, in example.com, example is the second-level domain of the .com TLD.
Single-letter second-level domains are domains in which the second-level domain of the domain name consists of only one letter, such as x.com. In 1993, the Internet Assigned Numbers Authority (IANA) explicitly reserved all single-letter and single-digit second-level domains under the top-level domains com, net, and org, and grandfathered those that had already been assigned. In December 2005, ICANN considered auctioning these domain names.
A domain hack is a domain name that suggests a word, phrase, or name when concatenating two or more adjacent levels of that domain. For example, bir.ds and examp.le, using the fictitious country-code domains .ds and .le, suggest the words birds and example respectively. In this context, the word hack denotes a clever trick, not an exploit or break-in.
