.dev is a top-level domain name operated by Google.[1] It was proposed in ICANN‘s new generic top-level domain (gTLD) program, and has become available to the general public on March 1, 2019, with an early access period that began on February 19.[2] To increase the security of the domains, the entire gTLD has been included in the HSTS preload-list.

History

Web developers have been using .dev top-level domains within their internal networks for testing purposes for a long time. However, after Google acquired the TLD, such environments have stopped functioning on some modern browsers.[3][4]
