Original GitHub issue: https://github.com/ovh/the-bastion/issues/177

when I try to ssh through my bastion an IPv6, I receive:

~ Unable to resolve host '<ipv6_address>' (IP <ipv6_address> version is not allowed)

It works fine with the IPv4 address of the host. The groupAddServer works with IPv4 and IPv6
Did I made something bad?

Hello,

I disabled IPv6 connections because this is not yet part of the automated tests stack, so I can't guarantee everything works correctly. As I knew we would want to support IPv6 at some point, most of the code has been written with this in mind so the fixes to get it working, if any is needed, should be minimal.

Now that there seems to be some interest, I'll add this to the todo list :)

Any news about IPv6 support ? It is a blocking issue as more and more infrastructure relay on it.

To activate the IPv6 support, I just replace this $v6 = 0 if not defined $v6; by $v6 = 1 if not defined $v6; on this file and this works in my case.

It's just a workaround. I hope one day the official IPv6 will come 😊.

To activate the IPv6 support, I just replace this `$v6 = 0 if not defined $v6;` by `$v6 = 1 if not defined $v6;` on this [file](https://github.com/ovh/the-bastion/blob/v3.16.99-rc2/lib/perl/OVH/Bastion/allowdeny.inc#L292) and this works in my case. It's just a workaround. I hope one day the official IPv6 will come 😊.

At some point we'll also need it internally, so I'll dedicate some time to work on it in the next few days/weeks.

As you said, it mostly works correctly already, but hasn't been extensively tested, so there are probably a few quirks here and there and I don't want to declare official support before having tested it enough, including adding IPv6 tests to the suite.

If you "force" enable it and see issues, don't hesitate to report them, though. :)
