IPv4

Term from Network Services industry explained for recruiters

IPv4 is the most common system for helping computers communicate over the internet and company networks. Think of it like a postal address system for computers - every device needs its own unique address to send and receive information. When you see numbers like "192.168.1.1" in job descriptions, that's an IPv4 address. Network professionals need to understand IPv4 because they're responsible for making sure all devices in an organization can communicate properly, just like a post office makes sure mail gets to the right places. While there's a newer system called IPv6, IPv4 is still widely used and appears frequently in job descriptions for network-related positions.
