MAP is all about stateless (NAT64 of Encapsulation) and IPv6 enabled access. MAP makes much more sense in any SP network having its internet customers do IPv4 address sharing and embrace IPv6.
What may make 'much more sense' in one network, doesn't necessarily make as much since in another network. As I understand it, MAP requires at least a software change on existing CPE, if not wholesale CPE change. Some providers may prefer to implement CGN instead if the capital outlay is less (and providing new CPE to customers through walkins or truck rolls can be problematic).
Our plan for my company at this time is to deploy native IPv4+IPv6 to all customers. While we are doing that, continue discussions and testing with CGN providers so that when we are unable to obtain anymore IPv4 addresses, we can then deploy CGN. Our hope is that we never get to the point of having to go CGN but we have to be ready in case that day comes and have our implementation and opt-out (if available) processes ready.
What devices does Cisco support MAP on? Specifically, does the DPC3827 support it?
