PSL

The Public Suffix List is a machine-readable list of domains (suffixes) under which names can be registered and used. For example, .com, .net, .coffee, pvt.k12.ma.us

The PSL is a Mozilla initiative but is community-maintained. It is primarily used by web browser manufacturers and other domain-related software.

This resource is crucial to the Universal Acceptance of TLDs.
