Due to Javascript, your IP address can be determined through WebRTC as well. Please note that changing WebRTC is not enough to change your IP. To change your IP you will also need a proxy, read the reasons and the how-to guides.
2 different IPs can be requested through WebRTC:
WebRTC Public IP
Your public IP should fit your real (or Proxy’s) IP address. By default Automatic WebRTC spoofing is enabled in Kameleo. It means that the WebRTC's public IP will match your real (or Proxy's) IP address.
WebRTC Private IP
This is the IP used on the internal network. The IP you receive from your Router. Something like 192.168.x.x. By default Automatic WebRTC spoofing is enabled in Kameleo. It means it will generate a commonly used private IP for your profile. This is a safe way to spoof it.
