There are two main types of domain extensions: country code extensions (ccTLDs) and generic extensions (gTLDs). Country code extensions like .de or .ch are governed by their respective countries, which set their own rules based on national laws. These can vary widely. Generic extensions like .com or .org are overseen by ICANN and follow standardized processes and term regulations. Certain mandatory customer information is required, which the registrar must provide.
Why are there different requirements, options, and regulations for domain extensions?
Basically, there are two types of domain extensions. The two-letter country code extensions (ccTLD = country code Top Level Domains) and all other extensions (gTLD = generic Top Level Domains).
Country code extensions (such as .ch, .de, .at) are subject to their respective countries. Each country defines its own rules and processes, adapted to the laws of that country. These can be very different.
All other extensions (such as .com, .org, or .swiss) fall under ICANN (the regulatory authority for gTLDs) and are subject to the same processes and term regulations. These processes require certain mandatory customer information that the registrar must send.
