What Is the History of .cba?

The .cba domain was delegated to the Commonwealth Bank of Australia on June 22, 2015, under ICANN's new gTLD program. The application faced delays due to name collision concerns, as the string 'cba' was in use on internal networks in Japan (matching Chiba Airport code) and within CBA’s own systems. Despite this, the domain was approved for exclusive use by the bank to secure its digital ecosystem and improve customer trust.
