addbindhost is one of the most useless and confusing misfeatures of ZNC currently.—@DarthGandalf

2015-06-29 07:49:18+0300 < Mikaela> DarthGandalf: so if you setuserbindhost, it's automatically added and used for all users too?
2015-06-29 09:15:18+0300 < DarthGandalf> Mikaela: no. addbindhost adds it to global list of hosts. If that global list is non-empty, non-admins are allowed to setbindhost only from that list. That's the only meaning of addbindhost
2015-06-29 09:16:15+0300 < DarthGandalf> poutine: znc -D
2015-06-29 09:16:17+0300 < Mikaela> DarthGandalf: but with the case of broken IPv6, isn't it wanted to addbindhost 0.0.0.0 so IPv6 isn't attempted by any user? I think the Happy Eyeballs issue isn't still fixed.
2015-06-29 09:16:44+0300 < DarthGandalf> Again. addbindhost 0.0.0.0 won't automatically fix it for any users.
2015-06-29 09:17:11+0300 < Mikaela> DarthGandalf: I thought that after adding it, ZNC sets all users to use that as they cannot use anything else?
2015-06-29 09:17:12+0300 < DarthGandalf> It will just limit non-admins' ability to setbindhost to select only 0.0.0.0 and nothing else (or whatever they have set already)
2015-06-29 09:17:49+0300 < Mikaela> in webadmin at least adding it there makes user default bindhost be "default" which is that and network bindhosts do the same

2015-06-29 09:18:12+0300 < Mikaela> I see. I will sduggest setuserbindhost in the future then?
2015-06-29 09:19:13+0300 < DarthGandalf> One more reason: if admin thinks that addbindhost actually limits users' bindhosts to one of list, they are wrong again: if setbindhost is "", OS will choose any IP on computer by usual rules
