BCP38 filtering on Mobile IP networks

I note that the MIT ANA tester is only for desktop OSs, and none of the
network tools I've collected for Android have BCP38 filter testing built
in.

Does anyone know if there are such tools for Android and for iOS?

I assume that tether testing from a PC would be useless, as the NAT
implementation would drop the packets -- does anyone know if there
are any leaky NAT implementations that *won't* drop packets with bogus
source addresses?

Or, alternatively, does anyone know *authoritatively* that any cell carrier's
mobile IP network already implements BCP38? And if so, why aren't they
bragging about it; at least here? :slight_smile:

I have added the Small Business page to BCP38.info.
