    Description

      New address picking scheme:

      • First we detect which addresses are available: IPv4 and/or IPv6 (dual-stack if both)
      • When we encounter an IPv4 address:
        • If dual-stack or IPv4 stack: use it
        • If IPv6-only stack: use it unless it is a class D (multicast) address: then convert it to an IPv6-mapped address
      • When we encounter an IPv6 address:
        • If dual-stack or IPv6-only stack: use it
        • Else: throw an exception (IPv6 address in an IPv4-only stack)
