Used for alternative naming systems outside the global Domain Name System (DNS).

Its purpose is to provide a namespace for experimental or non-standard naming schemes — such as peer-to-peer or blockchain-based networks — so they can coexist with the global DNS without risk of collision or confusion.

Refer to The .alt Special-Use Top-Level Domain (RFC 9476) for more information.
