In “automatic” tunneling, hybrid IPv4/IPv6 addresses are created by extending 32-bit IPv4 addresses to 128 bits by adding leading zeros. IPv6 packets are encapsulated within IPv4 headers, so that one ...

In hindsight, we reached peak IPv4 two years ago. The good news is that IPv6 is doing very well—but not nearly well enough. Is the IPv6 glass 1 percent full or 99 percent empty? “Hi, I’d like to sign ...

IPv6 is a powerful enhancement to IPv4 with features that better suit current and foreseeable network demands, including the following: IPv6 increases the number of address bits by a factor of 4, from ...

The Number Resource Organization warns that less than 10 percent of the IPv4 address space remains; it's time to start adopting IPv6. The warning comes after APNIC, the registry that hands out IP ...

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 ...

In this post, I will explain some of the basics that are easy to understand. Before we discuss the differences between IPv4 and IPv6, we need to know some of the basics of IPv4. Finally, I will ...
