ยท         Most Id-Loc split solutions need mapping server to look up efficiently for changes in locators of Identities. Scalability and performance of such mapping systems is not in scope.

This really doesn't make sense. The way I see it, the main downside of ID-locator split solutions *is precisely* the fact that the mapping system is hard to scale. Any scheme or solution that doesn't also address this scaling problem is undeployable at scale and therefore not useful to discuss in the context of any real deployment.

Not all Id/Loc systems are the same. Not all need to map Id values to Locators.

ILNP does not map Id values to Locator values.

ILNP uses DNS lookups (as for IP today) so that DNS names map to an Id/Loc pair. Then, nodes use direct signalling with Locator Updates as they move, and update DNS with new Locator values.

Updating DNS securely is possible today with, but deployed DNS engineering is not optimised for write operations. At the current time, at least, there is a significant performance hit with using DNS in this way.

So, overall, for ILNP, the scaling issues with Locator updates are related to the performance of secure DNS write operations.
