Indeed!

If you don't strip at least parts of the IPs, this is useless. At least
for IPv4, it would be easy to just recreate the hashes for all possible IP
combinations and match the hash ("rainbow table").

I see that one might prefer to strip the last one or two octets instead of
getting rid of the complete IP.
