IPTrk and XFF: Odd behavior when using same IP range as the system

[teward]

In a production environment, we have an IP range of, say, 1.2.3.0/24 at the 'corporate' environment. Of that, 1.2.3.162/29 is the IP range assigned use on the box itself.

When we set "xff_trusted_cidr" to [ "127.0.0.1/8", "1.2.3.0/24" ], IPTrk ends up ignoring the XFF header and setting the IP address in IPTrk to 127.0.0.1, but only for IPs fitting within the /24.

This is not expected behavior in which Trident would trust the headers from both the localhost and the IP address falling into the specified CIDR range that isn't local host.

This sounds a lot like a bug in how IPTrk parses XFF Trusted CIDR and handles the actual reading of XFF.
