I'm presently making a script to detect the IP adress of a VPN address.

When KIX detects The same IP adress and the same gateway in a ipconfig /all command, it conclude that the IP are the same and can know that this is the VPN adress and not the other IP adresses.

Here is my question:
this test txt file.

IP Address. . . . . . . . . : 192.168.0.53
Subnet Mask . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . : 192.168.0.53

The IP and Gateway are the same.

I run my code and KIX correctly detect both addresses (192.168.0.53) but he always thinks that they are different when comparing.

What have i done wrong?

Here is my script:
