.commbank domain extension

The .commbank domain extension belongs to the Commonwealth Bank of Australia, one of the country's largest financial institutions. It is a branded TLD used exclusively by the bank for its official online services. Access to register a .commbank domain is restricted to the bank itself. No external parties can register domains under this TLD. The Commonwealth Bank operates the namespace as a closed, internal space for its digital properties. The TLD was delegated to the bank in June 2015, following ICANN's new gTLD program. This lets the bank control its own corner of the internet, separate from generic .com or .com.au spaces. The registry runs on six name servers and offers both WHOIS and RDAP lookup services. The IANA record shows no registry URL for third party registrars because the domain is not open to the public.

The .commbank TLD was delegated to the Commonwealth Bank of Australia on 18 June 2015. It was one of the early brand TLDs approved under ICANN's new gTLD expansion. The bank applied for it to improve security and simplify its web presence. Before 2015, the bank relied entirely on .com.au and other traditional domains. The delegation gave it direct control over its namespace. The IANA report from June 2015 documents the formal approval and transfer of responsibility to the bank. Since then, the TLD has remained a closed, single entity namespace.
