Announcement: <a href="https://blog.tho.ms/network/2017/02/25/ip6-name-dns-record-any-ipv6-address.html" rel="nofollow">https://blog.tho.ms/network/2017/02/25/ip6-name-dns-record-a...</a><p>I had the idea when I needed a TLS certificate for a system without a global DNS record. I recalled that <a href="http://xip.io/" rel="nofollow">http://xip.io/</a> exists for IPv4, but didn't find something similar for IPv6. So I had to do it myself :-)
These names are incompatible with the "host" command-line utility, probably because looking up the A record returns NXDOMAIN instead of NOERROR.<p>NXDOMAIN means "this name doesn't exist, so don't bother asking for other record types."
