Supplementary question: I see in for 
freeradius 3.0.11:

  * "unlang" comparisons of IP addresses to IP prefixes are now
    detected, and types automatically cast.

But does that mean you can test for an IP address being within a prefix? 
If so, which operator would you use? I tried:

     if (&NAS-IP-Address == { ...

but got no match. A string expansion works though:

     if ("%{NAS-IP-Address}" =~ /^10\.254\./) { ...
