When Will We Stop Using IPv4?

When someone first starts learning about IPv6 they quickly come to understand that an IPv4-only node cannot communicate with an IPv6-only node and that dual-stack is the dominant transition method.  Now, six years after World IPv6 Launch, there is a growing amount of IPv6 traffic on the Internet and in the next few years we might observe IPv6 Internet […]

Last Network Standing: Your Life as an IPv6 Laggard

Imagine yourself in a future world where networked technology is fully integrated into our daily lives and self-driving cars are commonplace.  Most networks are wireless and almost all enterprise corporate applications are cloud-based.  IPv6 is now widely deployed across the Internet and in private networks, yet there are still traces of legacy IPv4.

IPv6 DNS Queries: A Work in Progress

Imagine what it was like to be an ancient mariner navigating the ocean blue at night using nothing more than stars, a sextant and a marine chronometer.  Thankfully, navigating the Internet is not as daunting.  The method that networked devices use to find their way around the digital ocean is the Domain Name System (DNS), […]

Even More Methods To Provide IPv4 as a Service (IPv4aaS) — Part 3

In the first part of this blog series we covered the rationale behind why organizations may prefer to run a single-protocol IPv6-only core. However, service providers must continue to provide service to subscribers who have legacy IPv4-only devices. The second part of the blog delved into several ways ISPs can create an IPv4 as a […]

How to Provide IPv4 as a Service (IPv4aaS) — Part 2

In the first part of this 3-part blog series, we discussed how IPv4 will soon become a legacy protocol.  In a few years, IPv6 Internet traffic volumes will surpass IPv4 Internet traffic volumes.  We also explored the motivation for service providers to build an IPv6-only core network yet still fulfill their obligations to connect customer […]
