.sui Domain Names

Not yet available

.sui is a proposed top-level domain that aligns with the Sui name and the wider Sui ecosystem. Publicly available evidence points to an application associated with Sui Naming Limited, but IANA does not yet list.sui in the root zone database, so it should be treated as prelaunch rather than delegated or generally available.
