I had a lot of errors so I'll just show the final version that works OK.<br>
<br>
=~ "192\.168\.([0-9]{1,3})\.([0-9]{1,3})<br>
<br>
The only drawback is that I could pass as valid 192.168.999.999 but as
these IPs come from a DNS query, I assume they'll be fine.<br>

I think you can reduce it to be just: "^192\.168\."<br>
<br>
Since it comes from dns server or socket attributes, then you are safe.<br>
<br>
The other option is to convert it to integer (with transformations) and
check it as net mask via bit wise operators.<br>
<br>
Cheers,<br>

Alex,<br>
<br>
Actually what I'm trying to do is check the IPs on a request on a
Kamailio+RTPProxy acting as border of our network.<br>
<br>
So I have the ingress IP and egress IP and need to check if I have to
bridge ii, ei, ie or ee.<br>
I managed to obtain all IPs in AVPs, but now I have to check if they
are public or private.<br>
<br>
So far our network uses only 192.168.x.x class for private servers.<br>
<br>
Thanks for the quick reply<br>

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.<br>
<br>
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.<br>

<div>Hi guys,<br>
<br>
Does anyone have a REGEX syntax to match a private IP on the
192.168.x.x range?<br>
<br>
I'm trying with:<br>
if($avp(s:ip_origen)=~"192.168(\.([1]?\d{1,2}|2[0-4]{1}\d{1}|25[0-5]{1})){2}"
)<br>
<br>
But all IPs pass as private, even public ones.<br>
<br>
Thanks!<br>
Uriel<br>
