I looked in the wiki for a utility function that would check if given ip address is private, but didn't find one. Does it exist?

Hello,
this one:
* https://www.kamailio.org/docs/modules/stable/modules/ipops.html#ipops.f.is_i...
I haven't checked if tests the newer ranges (e.g., carrier grade nat). The nat_uac_test() should have the recent ranges for non-routable ip addresses, just in case one wants to double check.
Cheers, Daniel

If it is really is based on RFC1918, then I doubt that it would handle IPv6 private addresses, since when that RFC was written, IPv6 didn't exist.

I haven't implemented the function, so I cannot comment more about its internals, but you can chain it with the match of subnet for private ipv6 using:

Of course, you can add a new function, if you want. An alternative coming in my mind is to add the subnets in address table grouped with an id that you use with allow_source_address().

But these could be used:
detailed_ip_type (ip, result) detailed_ipv4_type (ip, result) detailed_ipv6_type (ip, result)
-- Juha
You can use :
is_ip_rfc1918(variable)
