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.
How I Learned to Stop Worrying About IPv4’s Limitation and Love IPv6
If you remember back before the Internet was a “thing,” first of all don’t tell anyone – you’ll really date yourself. Seriously, for those of us who witnessed the birth of the “World Wide Web” and the phenomenal growth of the Internet, it’s hard to believe that we’ve exceeded the capacity of the original IPv4 […]
Where to Start Deploying IPv6 in the Enterprise
One of the common questions that often gets asked shortly after some introductory IPv6 training is “Where do I start deploying IPv6?” In the early years of IPv6’s adoption there were debates about how IPv6 should be deployed in enterprise networks. Should organizations start to deploy IPv6 at the core and then work their way […]
IPv6: Where are you on the Adoption Curve?
It is human nature to be curious about where you stand in relation to others. For example, organizations can be competitive and thus interested in making comparisons between their organization and others in their shared market segment. People also want to be individuals and stand out in a crowd (even at the risk of appearing […]
What You Need to Know about IPv6 Link-Local Addresses
In a recent article, I wrote about some of the common questions that IPv6 novices sometimes ask. We then asked the question, “What are the typical questions you get when teaching an IPv6 class?” Frequently, IPv6 instructors field questions from their students about IPv6 link-local addresses and how they work. This article builds upon the […]
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), […]
2017 North American IPv6 Summit: Highlights and History
There have been many IPv6 conferences over the past 15 years, but this year’s North American IPv6 Summit was something special. There was much rejoicing over the growth in IPv6 usage and celebration of many successful IPv6 deployments. This article will share with you the history of the event and the organizers behind this conference. […]
How to IPv6-Enable a Website Using a Content Delivery Network
There are many reasons why an organization would want to make their web site reachable over IPv6 transport. One reason is that due to IPv4 address exhaustion and more carriers deploying Carrier Grade NAT (CGN) and Large Scale NAT (LSN), your web site may perform better with IPv6. A second reason, related to IPv4 address […]
IT Nomenclature: What’s in a Name?
Nomenclature in computer and networking technologies can often be confusing and sometimes even funny.
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 […]
