[Kamailio-Users] Quick REGEX to match Private IP

[Alex Balashov]

172.16.0.0/12 does not line up on octet boundaries.  You will need to  
do something other than a regular expression.  Fortunately, 'src_ip'  
is a composite that supports comparisons against subnets in shorthand  
CIDR notation.

It might also be that whatever you are trying to accomplish can be  
done better some other way, but since you did not pose the question in  
terms of the objective, I cannot speak to that.
