[OpenSIPS-Users] check if ip address belongs to ip and subnet subscriber

[Vlad Paiu]

Hello,

Internally, when using ip.pton, OpenSIPS stores the binary 
representation of the IP as a character array ( due to the different 
size of IPv4 vs IPv6 ), so using the & will not work properly - that's 
why you're code snippet is not working as expected.  Will try to look 
and see how to fix this - if possible at all.

In the mean time, I'd strongly suggest using the permissions module - 
there is no performance penalty when reloading the address table ( while 
the new table info is loading, OpenSIPS will hold the old table info in 
memory , and once the loading is done there new and old IP lists will 
just be swapped ).

I'd suggest having a address groupid integer stored in the subscriber 
table which needs be added in the load_credentials param ( to be loaded 
at auth time ), and then run
     check_source_address("$avp(subscriber_grp)")
