% nc -6 cats-home.net 24554

with

# tcpdump -nlvv host 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a

in parallel, results in:

20:45:51.832045 IP6 (hlim 64, next-header: TCP (6), length: 32) 2a01:4f8:221:3dc1:900d:f001:dead:f001.37076 > 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a.24554: S, cksum 0x61f7 (correct), 101011674:101011674(0) win 14400 <mss 1440,nop,nop,sackOK,nop,wscale 7>

20:45:51.869458 IP6 (hlim 55, next-header: TCP (6), length: 20) 2a05:3580:de00:1687:21f:c6ff:fe1e:b46a.24554 > 2a01:4f8:221:3dc1:900d:f001:dead:f001.37076: R, cksum 0xd7e1 (correct), 0:0(0) ack 101011675 win 0

So, most likely the binkd there simply listens only at IPv4.
