I have checked all my r0kh records and r1kh records, plus the 
r1_key_holder and none of them include the MAC address of the radius 
server.  More to the point the MAC address of the radius server isn't 
listed anywhere in the hostapd.conf files.

I should say that the RADIUS server also acts as the default gateway to 
the internet, but with no WiFi hardware never acts as an AP.
