Finally, a great comment in this thread.
Arguably lack of IP address block portability is not that big a deal [now that we're well used to it]. But IPv6 did not solve the CIDR route table size issues, and that's a big failure.
I have long thought that IP packets should have a source and destination ASNs as well as actual addresses. That would mean that we'd need more DNS (or similar) lookups, and a bootstrapping system for that. A scheme like this would greatly reduce router table sizes and would allow for IP address block portability.
