Lack of NAT and an expectation of end-to-end reachability seem quite fundamentally different from IPv4 as it is deployed to day. (I'm not saying that NAT is a security feature, I'm just pointing to a rather significant difference.) IPv6 also make IPsec mandatory, which seems a significant change over IPv4, too. _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
