At the heart of the networking layer is addressing. IP addressing is used to locate computers and other network devices across the Internet. Currently, IPv4 is the dominant network addressing standard used on the Internet and within organizations. The problem is that we have exhausted our public IPv4 addresses. IPv6 was developed in part to address this very issue.
What are some immediate differences in the two protocols? Does IPv6 provide operational improvement, as well as increased address space? How has/will IPv6 impact organizations, the Internet, and you at home?
