ISO 3166-2:BJ is the entry for Benin in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions of all countries coded in ISO 3166-1.
.hk is the designated Internet country code top-level domain (ccTLD) for Hong Kong. It is administered by the Hong Kong Internet Registration Corporation (HKIRC), the only organization endorsed by the Hong Kong Government to undertake the administration of 'hk' domain names.

Punycode is a representation of Unicode with the limited ASCII character subset used for Internet hostnames. Using Punycode, host names containing Unicode characters are transcoded to a subset of ASCII consisting of letters, digits, and hyphens, which is called the letter–digit–hyphen (LDH) subset. For example, München is encoded as Mnchen-3ya.
In computer networking, a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication, such as the World Wide Web. Hostnames may be simple names consisting of a single word or phrase, or they may be structured. Each hostname usually has at least one numeric network address associated with it for routing packets for performance and other reasons.
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.
.bv is the Internet country code top-level domain (ccTLD) reserved for the uninhabited Norwegian dependent territory of Bouvet Island. The domain name registry and sponsor is Norid, but .bv is not open for registration. .bv was designated on 21 August 1997 and was placed under the .no registry Norid. Norwegian policy states that .no is sufficient for those institutions connected to Bouvet Island, and therefore the domain is not open to registration. It is Norwegian policy not to commercialize domain resources, so there are no plans to sell .bv. Should the domain later come into use, it will be under the regulation of the Norwegian Communications Authority and follow the same policy as .no.
.bw is the Internet country code top-level domain (ccTLD) for Botswana. It is officially administered by the Botswana Communication Regulatory Authority since 2013, previously being administered by the University of Botswana.
.sj is the Internet country code top-level domain (ccTLD) reserved for the designation Svalbard and Jan Mayen. The domain name registry is Norid, but .sj is not open for registration. The issuing of the domain was based on the ISO 3166 designation of Svalbard and Jan Mayen, which consists of two separately administrated integrated territories of Norway: the Arctic archipelago Svalbard and the nearly uninhabited volcanic island Jan Mayen. .sj was designated on 21 August 1997, at the same time as Bouvet Island was allocated .bv. Both were placed under the .no registry Norid, which is also the sponsor. Norwegian policy states that .no is sufficient for those institutions connected to both Svalbard and Jan Mayen, and therefore the domain is not open to registration. It is Norwegian policy not to commercialize domain resources, so there are no plans to sell .sj. Should the domain later come into use, it will be under regulation of the Norwegian Communications Authority and follow the same policy as .no. There are two second-level domains reserved for the two areas: svalbard.no and jan-mayen.no, but other web addresses are also used.
.co is the Internet country code top-level domain (ccTLD) assigned to Colombia.
.dz is the country code top-level domain (ccTLD) for Algeria.
The Internet country code top-level domain (ccTLD) .io is nominally assigned to the British Indian Ocean Territory. The domain is managed by Internet Computer Bureau Ltd, a domain name registry, with registrar services provided by Name.com.
.kr is the Internet country code top-level domain (ccTLD) for the Republic of Korea. Registrations are processed via registration agents.
.ky is the Internet country code top-level domain (ccTLD) for the Cayman Islands. The code was chosen as other possible options had already been allocated. Registration was limited to residents and registered companies in the Cayman Islands with a local address, but this restriction was removed in September 2015. The Cayman Islands also has the international three-letter code CYM and has won a bid to be awarded the .cym domain in a future expansion of the top-level domain space.
.lc is the Internet country code top-level domain (ccTLD) for Saint Lucia, sponsored by the University of Puerto Rico and created on September 3, 1991. The registry is operated by Afilias and markets towards companies structured as LCs, LLCs or PLCs due to the possibility of a domain hack, such as CompanyName.L.LC and supposedly better names.
.ma is the Internet country code top-level domain (ccTLD) for Morocco. A local registrar with a local Moroccan company as administrative contact is needed to register a .ma or .co.ma domain name. Further restrictions are imposed on the registering of other second-level domains.
.nc is the Internet country code top-level domain (ccTLD) for New Caledonia. Registry operations are managed by the Office des postes et télécommunications.
.no is the Internet country code top-level domain (ccTLD) for Norway. Norid, the domain name registry, is based in Trondheim, is owned by the state-owned Uninett and operates under supervision of the Norwegian Communications Authority. As of December 24, 2022 there were 843,749 registered .no domains. Organizations with a presence in Norway and registration at the Brønnøysund Register Centre are limited to 100 domains each. Individuals residing in Norway may register in the second-level domain priv.no and, as of June 17, 2014, directly under .no. Other second-level domains exist for organizations of certain types, such as municipalities and schools. The strict regulations have resulted in near-absence of cybersquatting and warehousing.
An IETF BCP 47 language tag is a standardized code or tag that is used to identify human languages in the Internet.

.ss is the designated country code top-level domain (ccTLD) for South Sudan in the Domain Name System of the Internet. It is derived from the ISO 3166-1 alpha-2 code for South Sudan, which is SS. According to CIO East Africa, the TLD was allocated on 10 August 2011 following the country's declaration of independence from Sudan. The TLD was registered on 31 August 2011, but not added to the DNS root zone and was thus not operational. It was approved at the ICANN Board meeting on 27 January 2019 and was added to the DNS root zone on 2 February 2019.
