.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 company) are the registries for the domain.

The auction was the "single sealed bid second price" model, in which the winner offers the highest bid and pays the second highest bid.
