Hi,
As we now have a set of mechanisms to transport IPv6 over IPv4 standardized, and as it seems we will probably end up having a set of mechanisms to access IPv4 destinations over IPv6-only access (MNAT-PT, SNAT, NATv4v6v4…), has there been discussion already how a host that implements multiple transition technologies should efficiently and automatically discover which mechanisms to use in access networks it happens to attach (and move between)?
Is the current state of the art just: trial & error, provisioning by non-IETF means, or as defined by other SDOs for their systems?
Best regards,
Teemu
