Connection check – if you are having internet issues, the IP address helps technical support see if you are connected and from which range.
Network setup – when connecting printers, cameras, servers, or smart devices at home or in the office.
Remote access – if you want to connect to your computer or NAS server while away from home.
Geolocation – identifying the approximate place you are connecting from (useful for services that offer local content, but also for security checks).
Security monitoring – you can track whether someone is using your internet without permission or trying to enter your network.
VPN or gaming setup – for online games, hosting servers, or securely connecting to a work/school network.
Someone might want to know their IP address because:
they need to share it with a colleague or technician who must connect to their device,
they want to check if they are using a static or dynamic IP address,
they want to see how they "appear" online (for example, whether websites recognize them as being in their country or elsewhere).
In short: an IP address is like a home address on the internet – it allows devices to find and communicate with each other.
