What is .hotmail?
Brand TLDs operate under Specification 13 of ICANN's registry agreement. It lets a trademark owner keep every second-level name for itself, so you won't find .hotmail names for sale at any registrar.
ICANN's records put the delegation of .hotmail on June 10, 2015. Like most of the newer endings, it was applied for in the 2012 New gTLD Program round and its registry agreement was signed on December 18, 2014.
Microsoft Corporation also runs 7 other TLDs, including .azure, .bing, .microsoft, .office and .skype.
Under the hood, the root zone points to 8 name servers for .hotmail, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .hotmail haven't been tampered with on the way. Registration data is published over RDAP.
