What is .host?
ICANN's records put the delegation of .host on May 31, 2014. Like most of the newer endings, it was applied for in the 2012 New gTLD Program round and its registry agreement was signed on April 17, 2014.
Radix Technologies Inc SEZC also runs 9 other TLDs, including .fun, .online, .press, .site and .space.
Under the hood, the root zone points to 4 name servers for .host, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .host haven't been tampered with on the way. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.host).
