An IP address (Internet Protocol) is a unique number that identifies every device connected to a network that uses the Internet Protocol to communicate. It works as the "postal address" of your device in the digital world, allowing other devices and servers to know where to send the requested information.
Knowing your IP address can be useful for several reasons: configuring networks, troubleshooting connectivity issues, accessing remote services, verifying your approximate geographic location, and better understanding how your internet connection works. Additionally, some online services may require you to know your IP to configure secure access or whitelist.
There are two main types of IP addresses: public IP and private IP. Your public IP is what you see on this page and is visible from the internet. Your private IP is what your router assigns to devices within your local network (like your computer, phone, smart TV, etc.) and is only visible within that network.
Currently, two versions of the IP protocol coexist: IPv4, which uses 32-bit addresses (like 192.168.1.1) and is running out due to internet growth, and IPv6, which uses 128-bit addresses and provides virtually unlimited address space for the future of the internet.
Depending on your internet provider, your IP address can be dynamic (changes periodically) or static (stays the same). Most home users have dynamic IPs that change every time they restart their router or after a certain period of time.
