What is my IP?
Your public IP address is the unique identifier assigned to your internet connection by your ISP.
What is an IP address?
An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network. It serves two main functions: host or network interface identification and location addressing.
IPv4 vs IPv6
IPv4 uses 32-bit addresses (e.g. 203.0.113.1), while IPv6 uses 128-bit addresses (e.g. 2001:db8::1). IPv6 was created to address the exhaustion of IPv4 addresses.
Why does my IP change?
Most residential ISPs assign dynamic IPs that change periodically. Static IPs are fixed and usually require a business plan.
