In the world of networking, most people are familiar with IPv4. These numerical labels, like 192.168.2.1, have identified billions of devices on the internet for decades and have been responsible for connecting those devices to the internet for decades at this point. As of 2025, less than half of Internet traffic is over IPv6, meaning IPv4 still carries the majority of data despite its fundamental limitation of using 32-bit addresses. IPv4 has been on life support for years on account of its 4.3 billion address limit, leading to the advent of IPv6 with its 128-bit address space.
