IPv4 vs IPv6
Compare IPv4 and IPv6 address formats and why both are used on today’s internet.
IPv4 uses 32-bit addresses commonly written as four decimal numbers separated by dots. IPv6 uses 128-bit addresses written in hexadecimal groups, providing a vastly larger address space.
A connection may support IPv4, IPv6, or both. Which address a website sees can depend on your provider, device, browser, destination, and network configuration.
