IPv4 protocol, the previous standard, consists of four number strings — each containing three digits separated by dots. A standard IPv4 address is bit and looks something like With wireless and network-attached devices increasing rapidly by the day, the internet will exhaust all unique IPv4 addresses at some point.

Though, the IP address exhaustion problem that is looming on the horizon. To come up with a new standard of network layer protocol that allows more unique IP addresses to be created, IPv6 was standardized.

IPv6 protocol, which is bits, consists of eight numbered strings, each containing four characters alphanumeric , separated by a colon. This gives us an unbelievable amount of unique IP addresses; ,,,,,,,,,,,, to be precise. It also assures that we will not run out of unique IP addresses to assign to new devices anytime soon. The differences between IPv6 and IPv4 are in five major areas: addressing and routing, security, network address translation, administrative workload, and support for mobile devices.

IPv6 also includes an important feature: a set of possible migration and transition plans from IPv4. Of course, there are standards and protocols and procedures for the coexistence of IPv4 and IPv6: tunneling IPv6 in IPv4, tunneling IPv4 in IPv6, running IPv4 and IPv6 on the same system dual stack for an extended period of time, and mixing and matching the two protocols in a variety of environments.

IPv6 was built from the ground up to be capable of end-to-end encryption. The encryption and integrity-checking used in current VPNs is a standard component in IPv6, available for all connections and supported by all compatible devices and systems. Widespread adoption of IPv6, when properly implemented, could therefore make man-in-the-middle MITM attacks significantly more difficult. However, there are also notable benefits in IPv6 for mobile devices, which will be able to maintain the same address when moving from one connection to another — going from a 3G network to Wi-Fi provided by your local coffee shop, for example.

These changes not only provide greater speed, simplicity and usability, but also make connections more resilient and secure.

Given the prevalence of mobile devices today, this enhancement should be most welcome. This test site will return a fully-qualified IPv6 address in the second Summary bullet point. Note: These instructions have been tested with macOS Skip to main content.
