I'm looking at both, and, frankly, LSN (large scale NAT) is not as
trivial as you think. I actually talk to and work with some of these
very large providers on a regular basis. None of them is looking forward
to deploying LSN with anything but dread. The support issues, user
experience, CALEA problems, and other issues with LSN are huge. None of
them that I am aware of are considering using lSN to free up addresses
to hand over to hosting providers.
Well said.
I've been pondering LSN lately. I think people have haven't been involved
in large scale service changes or migrations can't appreciate just how
many unanticipated edge cases can appear and blindside a project.
I expect that deploying IPv6 will be far less problematic than deploying
LSN for a large ISP.
