Can someone explain what is IP version 4 in simple terms? or What is IP version 4 and why is it still

IPv4 is like giving every device a unique ID (e.g., 192.168.0.1). When you send data, routers read the IP and forward it.

Problem? We’re outta addresses. IPv6 solves this but isn’t fully adopted yet.

For hands-on learning, spin up a home lab with old routers or use GNS3. Seeing what is ip version 4 in action beats theory!
