The IPv6 Tipping Point Effect
If you were the first person to use IPv6 on the Internet, there was no one to talk to. That is a bit like being trapped on a deserted IPv6 island surrounded by an ocean of IPv4 with nothing but a volleyball for a friend. Thankfully, now, there are many Internet systems that use IPv6 so the world isn’t as lonely. However,…
IPv6 and Internet Privacy
Privacy and the Presence of Pervasive Monitoring What comes to mind when you think about the topics of pervasive monitoring and mass surveillance? Does your mind immediately conjure up images of the Eye of Providence or, more popularly, the Eye of Sauron from J. R. R. Tolkien’s The Lord of the Rings epic saga? There are so…
Dr. StrangeIPv6 or: How I Learned to Stop Worrying About Hosts and Love a /64
I want everyone to think of IPv6 in terms of 64 bits. (Yes, I know that IPv6 is really 128 bits for the address, but as you’ll discover that isn’t the point I am trying to make!) Now that we have that out of the way, let’s talk about why it’s better to think of IPv6 in terms of the network address space (i.e., the…
A /48 For Every Site and For Every Site a /48 – Part 2
Part one of this blog reviewed the concept of a site in IPv6 address planning. It also discussed the reasons why a /48 is considered the preferred prefix size for assignment to a site. This time around, we'll take a look at what to do with a /48 once you've assigned it to a site. As with other IPv6 prefixes, the sheer…
IPv4 the Hard Way, IPv6 Made Easy
Among my many IPv6 roles, I am a cohost – along with Ed Horley and Tom Coffeen – of the IPv6 Buzz Podcast available through Packet Pushers. We recently recorded an episode of IPv6 Buzz with Rick Graziani. Rick is a Computer Science (CS) and Computer Information Systems (CIS) instructor at Cabrillo College, an adjunct…
A /48 For Every Site and For Every Site a /48
(Oprah IPv6 meme courtesy of Scott Hogg!) Among the available IPv6 address planning principles, the general rule of assigning a /48 per site is particularly significant and beneficial. It's significant because it acknowledges a basic unit of address resource consumption with IPv6. And why is that? Well, given that…
IPv6: It’s Not You, It’s Me
There seem to be some “issues” with enterprise’s relationship with IPv6. It isn’t clear if they just aren’t getting along or if enterprise is in a monogamous exclusive relationship with IPv4 and unwilling to explore the dual-protocol swingers’ lifestyle. Maybe conservative enterprises are “IPv6-curious” and fear reprisals…
The Problem Isn’t the Price of IPv4
Among the IPv6 community it is very common for the business and financial justification discussion to devolve to a simple point around the price of acquiring IPv4 address space. It seems the community has done a poor job of articulating any other feasible argument around helping the business and financial teams to want to…
Why an Investment in IPv6 Training Will Pay Off
It is a given in the IT industry that training and education (formal or informal) are critical parts of any team attempting to learn new skills and technology. It is not possible to keep up with the pace of change and innovation that happens in IT without a focused effort on learning new things. This comes in many forms…
IPv6 Back to Basics: Interface IDs
Introduction Besides the virtually unlimited address space (a quantity that experts have argued will likely outlast the lifespan of the protocol itself), IPv6 offers many unique characteristics and features that are not found in IPv4 (i.e., the legacy Internet Protocol). The original designers of IPv6 made sure to take…
