IP address (not similar?)

[juststones]

Hello, I've the following question:

Why is there a difference between the two IP-addresses below:
- My IP address at "ipconfig" (windows)
- My IP address at whatismyip.com

Why are above IP addresses not similar?

Thank you,
Dennis.

- My IP address at "ipconfig" (windows)

Your internal (LAN) address. Used for computers on your own network to communicate with each other. Usually **2.*68.*.*


- My IP address at whatismyip.com

Your external (Internet) address. Your router uses this address to communicate with the Internet, and multiple computers on the network communicate through the router to the Internet using NAT.
