By offering a 128-bit enough addresses to support it. addressable space, it can provide 4.3 billion protocal: IP addresses for every person on the planet— Today, there are 7 billion people on the planet enough to meet everyone’s needs for the understanding and even more devices connected to the foreseeable future. the IPv6 future Internet. Network Address Translation (NAT) How you can navigate the upgrade path from IPv4 to IPv6 How many IP addresses can IPv6 create?

38 Picture unique IP addresses IPv4 = 4 billion addresses— IPv6 = 3.4x10 addresses— as grains of sand. Enough “grains” to fill Enough to fill the earth a wheelbarrow. 1 million times.

User guide 1 The promise of IPv6 Aside from the need for more IP addresses, there are plenty of reasons to make the move from IPv4 to IPv6:

Easier network Direct end-to-end Increased security Continued innovation management connection IPsec is built into the IPv6 With the number of addresses IPv6 networks provide Due to the size of the address, protocol and usable with a and the scalability and flexibility auto-configuration capabilities. IPv6 eliminates the need for suitable key infrastructure. of IPv6, it offers great potential They are simpler, flatter and NAT devices. for driving innovation and more manageable—especially supporting collaboration. for large installations.

Preparing for deployment Step 1. Take an inventory of all the connected infrastructure without impacting your Getting ready for IPv6 is a devices on your local area network (LAN). network performance. three-step process: You’ll need to make sure routers and all A dual-stack deployment provides two IP client devices, such as printers, PCs, office addresses at the same time. Devices receive Step 1 phones and other IP machines can support both an IPv4 address and an IPv6 address, Inventory devices. IPv6. Fortunately, most modern operating allowing applications and devices to use the systems—and many applications—are protocol that best meets their needs.

IPv4 and IPv6 will coexist for IPv6 standards in the mobile industry can’t many years during the transition. By utilizing a accommodate IP addresses that never change, Step 3 dual-stack implementation, you can run both so it’s important to begin evaluating how this Plan ahead.

Extending the life of IPv4 Making the migration easier Registration You may have servers, remote cameras, Once you’ve identified which solutions Another approach that can provide connectivity network printers, monitoring stations, sensors currently require a static IP address, it’s to remote terminals is to use a registration and other machines with static IP addresses time to consider how to support them in server to manage the current addresses and that no longer need to connect remotely with an IPv6 world.
