merckmsd (.merckmsd)

.merckmsd is a generic top-level domain (gTLD) for the pharmaceutical company Merck, operating in the U.S. as Merck & Co., Inc. The domain is sponsored and managed by MSD Registry Holdings, Inc., based in Kenilworth, New Jersey. This TLD is a branded domain, meaning it is intended for exclusive use by the sponsor and its affiliates to control the company's online presence. There are no open public registrations; eligibility is restricted to MSD and its related entities. The IANA record shows it was delegated in June 2017, with the administrative contact using a merck.com email address, confirming the corporate tie. GoDaddy Registry handles the technical backend. This is a classic example of a company using its own TLD for security and brand management.
