Presuming a user hasn't thought to fake the REMOTE_ADDR or REMOTE_HOST
environment variables you could check those against a list of known
addresses (or parital addresses, say 210.136.161.* for docomo) without
incurring the cost of a reverse lookup.

All depends on how determined a user is to get at your data.
