Public addresses are assigned by InterNIC and consist of class-based network IDs or blocks of CIDR-based addresses (called CIDR blocks) that are guaranteed to be globally unique to the Internet. When the public addresses are assigned, routes are programmed into the routers of the Internet so that traffic to the assigned public addresses can reach their locations. Traffic to destination public addresses are reachable on the Internet. For example, when an organization is assigned a CIDR block in the form of a network ID and subnet mask, that [network ID, subnet mask] pair also exists as a route in the routers of the Internet. IP packets destined to an address within the CIDR block are routed to the proper destination. In this post I will show several ways to find your public IP address from Linux terminal. This though seems like a waste for normal users, but when you are in a terminal of a headless Linux server(i.e. no GUI or you’re connected as a user with minimal tools). Either way, being able to get public IP from Linux terminal can be useful in many cases or it could be one of those things that might just come in handy someday.
