What is Public vs Private Addresses?
Public IP addresses are globally unique addresses assigned by Internet Service Providers and are reachable over the Internet. Private IP addresses are reserved for use within local networks and are not routable on the public Internet (ranges like 192.168.x.x, 10.x.x.x, and 172.16.x.x are commonly used internally). Devices with private addresses access the Internet through a process called NAT (Network Address Translation), which maps multiple private addresses to a single public one.
