I'm looking for more information about having IPv4-only devices (embedded, legacy, etc) on a network that is otherwise IPv6-only, with IPv6-only Internet access. It's academic at this point, but I can ...

A possible fix arrived in December 1995 in the form of RFC 1883, the first definition of IPv6, the planned successor to IPv4.

The National Institute of Standards and Technology (NIST) warns that moving from IPv4 to IPv6 is a process fraught with peril, which may explain why government agencies are so far behind their own ...

If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out of addresses but have ...

The switch to IPv6 – on 6 June – shows just how imminent the transition from IPv4 to IPv6 is. The 32-bit IPv4 address space can support 4.3 billion addresses and IPv4 addresses are running out. In ...

It would have been so easy if the early Internet and TCP/IP network designers had made IPv6 backward compatible with IPv4. They didn't. In 1981, IPv4's 32-bit 4.3 billion addresses look more than ...

In this chapter, you will learn about the addressing used in IPv4 and IPv6. We'll assign addresses of both types to various interfaces on the hosts and routers of the Illustrated Network. We'll ...

Users of Internet Protocol version 4 (IPv4) networks, beware man-in-the-middle attacks. That's because such networks can be exploited using capabilities built into IPv6, the next-generation standard ...

We just saw that the mask determines where the boundary between the network and host portions of the IP address lies. This boundary is important: If it is set too far to the right, there are lots of ...
