IPv4 and IPv6

IPv4 and IPv6 are systems for assigning unique addresses to devices on the internet, allowing them to communicate. IPv4 uses 32-bit addresses, providing about 4.3 billion addresses, which has become limited as more devices connect. IPv6 uses 128-bit addresses, offering an almost unlimited number of unique addresses, ensuring ample capacity for future growth. Think of IPv4 as a traditional phone number system with limited lines, while IPv6 is like a new, expanded system designed to accommodate the rapidly growing number of internet-connected devices.
