The usual way to get the assigned ip would be to process radius accounting. Accounting records would also fill your session database which radwho.cgi could then query.

Accounting would get you start, stop and interim records which all included the actual assigned ip.

This would also let you have the nas assign the ips which is also much more stable in the long run.

Greetings
Christian
