Opinions differ on that. Every proposal to add that one extra level of indirection into the Internet architecture, whether it is deploying home agents, binding applications more tightly to DNS, or adding indirection into the routing, is going to make someone's life more difficult and some application perform less well than it did in the perfect network where every site was singly attached and every host was stationary. Therein lies the deadlock. Regards, // Steve _______________________________________________ nat66 mailing list [email protected] https://www.ietf.org/mailman/listinfo/nat66
