Types and characteristics of domains

There are two main types of domains: gTLD and ccTLD.

gTLD(generic Top Level Domain)

gTLDs are domains such as '.com', '.net', and '.org' that can be registered by anyone in the world.

ccTLD(country code Top Level Domain)

ccTLD is a top-level domain assigned to each country or region, and ".jp" (jp domain) can be used in Japan. The JP domain has the following characteristics.

  • Only individuals and organizations with addresses in Japan can register
  • The registrar lock function cannot be used
  • Organization names or personal names are displayed even when using the Whois information disclosure proxy service.

jp domains can be divided into three types: general-purpose JP domain names, prefecture-type JP domain names, and attribute-type/region-type JP domain names.
