With the ICANN's New gTLD Program, One.com applied for management of the .one TLD.^[4] One.com won at private auction with Radix Registry the rights to the ".one" string.^[5] The auction was the "single sealed bid second price" model, in which the winner offers the highest bid and pays the second highest bid.^[6]

As of September 2022, .one was the 27th-most registered top-level-domain on the Internet, with 187,874 registrations. One.com was the second highest registrar for .one, out of its 107 accredited registrars.^[7]
