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
