"Today’s network is a version of a named network, and the role of IP addresses is ephemeral session-level tokens that allow the network to distinguish between concurrent packet flows and little else."

an interesting viewpoint!

Indeed! Especially when you look at QUIC's Connection Identifier to allow seamless roaming. At that point the IP address serves the session token role even less.

The unfortunate part of the evolution of the network is today there is far too much distinction between client and server rather than peers performing end-to-end communication. NAT works far too well because of this asymmetry.
