How do you define "what host"? If it's by MAC address (and you are not
using temporary, cryptographic or random addresses), then the MAC is in
the address the host ends up using.

Also, as someone else said, hosts don't "get" addresses via SLAAC - they
generate them. That means that while you may be able to predict what
they *will* use, you would need to snoop NDP to find out what they *are*
using, and even more so for temporary, cryptographic and random
addresses.

I have no experience of anything that actually does this, but it would
be fairly simple to do. NDP will end up snooped in routers and switches
for lots of reasons, so expect to see such features in real kit pretty
soon. Make sure you let your vendor know what you want/need...
