Basic Knowledge

Domain Name Structure

Domain names have a hierarchical structure from right to left. For www.example.com, com is the TLD (Top-Level Domain), example.com is the registered second-level domain, and www is the subdomain.

Types of TLDs

gTLD：gTLD stands for generic Top-Level Domain, such as .com and .net, which can be registered worldwide regardless of purpose or industry.
ccTLD：ccTLD stands for country-code Top-Level Domain, such as .jp (Japan) and .uk (United Kingdom), which are assigned to specific countries or regions.
