Default configuration of AS7 is distributed as force to use IPv4 network stack only (even IPv6 network stack is available on hosting platform). There is several steps and requirements to re-configure AS7 installed instance to allow it utilizing the IPv6 network stack and environment too (or use it exclusively).

This is very important in pure IPv6 network stack environment, because in a such environment default installation isn't able to start at all.

The issue is that there isn't any User Guide or other documentation how user should re-configure its AS7 instance to work in an IPv6 environment.
