How dit you do the scan?

# nmap -pbinkp -6 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a

Starting Nmap 6.47 ( http://nmap.org ) at 2017-12-18 15:18 CET
Nmap scan report for SkyNet-Best-ISP-in-StPetersburg-Russia.sknt.ru (2a05:3580:de00:1687:21f:c6ff:fe1e:b46a)

I'm seeing the same result for every way I try the IPv6 address (binkd, telnet using the hostname, telnet using the direct IPv6 address)...

# telnet 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a binkp
Trying 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a...

Bye, Wilfred.
