[OpenSIPS-Users] How to ensure current IPV6 listening address

I am reluctant to take out a github membership to simply request a feature. 
Perhaps someone with an existing membership could request the feature.

Opensips currently is unable to detect the IPV6 address of an interface when 
given the interface name in the configuration. This is a request to implement 
that capability.
