.tez TLD

Currently, the only supported top-level domain is .tez. On testnets, it's always named after the name of the protocol (e.g. .delphi, .edo, etc.) to avoid potential confusion between a testnet and the mainnet. You can find the corresponding TLDRegistrar addresses in the Deployed Contracts section.

Label Validation for .tez

In addition to the rules specified in Name Validation and Normalization, the top-level domain requires all labels to only contain the Latin characters a-z, 0-9, and hyphens (-). Hyphens cannot appear as the first or the last character.
