What is .post?
.post is one of the older generic TLDs: ICANN records its delegation as August 7, 2012, long before the 2012 expansion.
Under the hood, the root zone points to 6 name servers for .post, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .post haven't been tampered with on the way. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.post).
