...realm
The term realm [15] is used as it is used with current NAT, to designate a collection of interconnected hosts across which the IPv4 addresses are unique.

...TRIAD
TRIAD is an acronym, originally standing for Translating Relaying Internet Architecture integrating Active Directories but it might also stand for Time to Rescue the Internet from Address Depletion.

Packets are addressed to host interfaces, not to hosts, the same as the original Internet architecture.

This assumes the gateway already has one such address if the WRAP RAs communicate over the existing wide-area IPv4 infrastructure.

...IPv6
One could argue that the Internet does not actually need more global addresses, by relying on efficient allocation and NAPT, given only about 1 percent of the IPv4 addresses are actually in use. However, this argument makes IPv6 even less compelling and WRAP is still beneficial for other reasons, such as connecting private address domains.

...MPLS
One of the original motivations for MPLS, efficient IP forwarding, has been eliminated by the advent of wire-speed hardware IPv4 forwarding engines.

...effective
Conventional header compression works best on long-lived connections, such as telnet sessions over dialup links. However, cellular phone data services have been most successful with short message services, for which the gains are less clear.

At the time of writing, China has approximately 7 million global addresses, enough to support approximately 500 billion simultaneous connections using NAT-PT.

...cost
For instance, a modern hardware router can forward IPv4 packets at 50 million packet per second yet only forward IPv6 in software at roughly 50 thousand packets a second.
