.one is a top-level domain. It was proposed in ICANN's New generic top-level domain (gTLD) Program, and became available to the general public on May 20, 2015. One Registry (a subsidiary of One.com A/S) and ARI Registry Services (a Neustar[2] company) are the registries for the domain.[3]

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]
