What is a Zone?

A zone is defined by the active top-level domains (TLDs) given by ICANN, such as .com, .net, or .uk. Second-level domains like .co.uk belong to the corresponding TLD and do not form their own zone.

What is a Domain?

A domain refers to the registered main name without subdomains. For example, in blog.example.com, the domain is example.com. Third-level domains like *.blogspot.com are not counted as separate domains, though we collect all subdomains for several services .

How often are the domain lists updated?

Domain lists are updated daily at 14:00 (CET). The API always operates with the latest available information.
