DOMAIN EXTENSION GUIDE

.sub Domain Names

Application announced

The.sub string is presented here as a proposed top-level domain rather than a delegated live extension. Publicly announced information identifies Link Freedom Group as the applicant associated with.sub, with disclosure dated 13 August 2026. ICANN’s 2026 round materials also indicate that final applied-for strings are published at String Confirmation Day, so the most reliable public context for.sub at this stage is applicant disclosure rather than live registration status.
