The easiest way to see what IP your computer or phone is currently using when contacting Internet is to go to a web page that displays it.
- Please go to an external server like www.whatismyip.com which also does some geo-localization and shows what ISP (Internet Service Provider) you currently are using.
How to look up the local IP-address on different operating systems:
Your local IP-address may be translated into another external IP-address over a router using NAT (network address translation).
On a Mac this is also displayed in System Preferences:
Open the Network tab in System Preferences and go to active interface to see the IP-address. Example 22.214.171.124
Open Advanced. The IP-address is displayed again.
Check MAC-address in Advanced. Example a8:20:66:19:5b:b8
For Linux (or macOS) open a terminal and type ifconfig.
For Windows, open a command window and type ipconfig /all
Example: IP-address is 126.96.36.199 and MAC-address is 08:00:27:27:06:ad
The command getmac also display the currently used MAC-address.
