Getting client IP address

Anyone know how to get the client IP address?

As part of the authentication/stats/logging system, we'd like to have all IPs stored in the database... but I can't for the life of me find out how to get it (searching the flash docs returned nothing, and google keeps bringing up people asking for IP in flash and then being told to use PHP/CF to do so...).

There definitely has to be a a way to get the ip.

Thanks.
