IP address space

An IP address space is the range of unique numbers assigned to devices on a network, serving as their digital address for communication. Think of it like a postal system where each house has a specific address. There are two main types: IPv4, which uses four sets of numbers (like 192.168.1.1), and IPv6, a newer, larger system to accommodate more devices. The address space defines how many unique addresses are available within each system, ensuring devices can identify and connect to each other reliably across local and global networks.
