Right. That works great in an environment where the regulators
require that every telco pay Neustar to maintain the LNP databases,
and send all the updates promptly when a number is ported or
disconnected.
The telcos pay Neustar $300 million a year to run the database. I'm
sure they'd be delighted to run a similar database for IP networks at
a similar price. Of course, that just handles the networks in the
U.S.
