IPv6 was designed in a day where IPv4 security problems were still minimal. meanwhile, IPv4 enterprise networks have acquired all manner of security baggage. those products just barely exist for IPv6, if at all, and they're not proven yet. even enterprises that want to adopt IPv6 because they understand its advantages find it somewhat difficult. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
