This should be discussed with adc hub soft developers so we can all come toegether and figure this out. Something as simple as sending a host name or ip to regserver should be enough to develop a pinger to get the rest.
Sadly it looks like most of DC devel is dead by now. Only actively developed soft is verlihub by Rolex.
....
M8 is luadch-ng your project??? Did you fix this in your soft ???
I mean its not really a bug its confusing but last reply in this thread fixes issue.
Can you make sure this code is changed in next lua-ng releases???
Open ./core/hub.lua
Replace
if not ( cid and pid and nick and infip ) then
with
if not ( cid and pid and nick ) then
I don't understand why it takes 3 years to fix this.

Else all legacy pingers will get disconnect and no info for hublist.
