IP may be leaking?

[User of AirVPN 46]

Hi there everyone!
Today I was runnning netstat -nbt on CMD in Windows with the intent to get the IP address of a game server I was connected to.

But as I scrolled down, I saw this:

 

[skype.exe]
  TCP    10.4.50.209:4855        xxx.xx.x.xxx:8080      ESTABLISHED

The xxx.xx.x.xxx is my real IP address (I was running this command while connected to AirVPN). I wasn't sure if this was normal for my IP to appear here, so I ask everyone here.

Is it normal to be seeing my real IP address in netstat -nbt? If not, how can I prevent it?
