Understanding IPv6: What Is Solicited-Node Multicast? (Part 4 of 7)
IPv6 solicited-node multicast somtimes seems to confuse those new to IPv6 in the beginning. I think this is because it seems so foreign and new. In this post, we will explore exactly what IPv6’s solicited-node multicast is and the rules of creating such an address as told to us by RFC 4291.
However, before we start on what’s new and different, let’s look at what solicited-node multicast has in common with IPv4 and IPv6 constructs that we already know.
In this blog post, we looked at IPv6 link-local scope multicast addresses. One of the examples was FF02::A. This address is for all devices on a wire that want to “talk” EIGRP with one another.
Focusing specifically on FF02::A and how routers join it, we can see and say three things:
- Local: FF02::A is local to the wire.
- Join: Each device “joins” FF02::A by just “deciding to listen” to the IPv6 link-local scope multicast address FF02::A. Then, by extension, it listens to the corresponding MAC address for that multicast IPv6 address (33:33:00:00:00:0A).
- Common interest: As we can see, these varying groups have something in common that they would all like to hear about. For FF02::A, the common interest — the “connection” Continue reading

Short Take: The Broadcom SDKLT Announcement
My first short take at The Network Collective is up discussing the Broadcom SDKLT announcement. Does this really mean the end of vendors or network engineering? You can guess my answer, or you can watch the video and hear it for yourself.
Future Thinking: Niel Harper on Cyber Threats
In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. In February 2018, we interviewed two stakeholders – Cyrating, a cybersecurity ratings agency, and Niel Harper, Senior Manager, Next Generation Leaders at the Internet Society – to hear their different perspectives on the forces shaping the Internet.
Niel Harper is a Young Global Leader at the World Economic Forum. He has more than 20 years of experience in the areas of telecoms management, cybersecurity, IT governance and strategy, ICT policy research and advisory services, and program management. (You can read Cyrating’s interview here).
The Internet Society: Experts predict an increase of frequency and impact of cyberattacks. What form are they likely to take in the future?
Niel Harper: In the foreseeable future, attackers are likely to fall under three categories: organized criminals seeking to profit from malicious online activities, online protesters (also known as hacktivists), and governments who target their own citizens or target other governments, whether for cyberespionage or cyberwarfare.
Criminals will continue to become more organized, selling Continue reading
Wireless Doctors
Wireless is a complicated thing. Even when you try to distill it down to networking basics on the wired side of the access point, you still have a very hard problem to solve on the radio side. Even I’ve talked in the past about how wireless is now considered a “solved” problem. But, the more I interact with wireless professionals and the more I think about the problem, the issue isn’t that IT departments think wireless is solved, it’s that they don’t appreciate the value of a specialist.
The Last Place Doctor
There’s an old joke that goes, “What do you call the person that graduated last in their medical school class? Doctor.” Professionals spend a lot of their time learning a tradecraft and practicing it to get better. And it’s not just doctors. So do plumbers, electricians, and teachers. Anyone that has ever tried to do any of these trades will tell you that the basics are capable of being figured out by the average non-professional, but the details are a huge leap.
You’d never assume that being able to put on a Band-Aid on a scrape would qualify you to do brain surgery. Or that changing a Continue reading
Future Thinking: Cyrating on Cyber Threats
In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. In February 2018, we interviewed two stakeholders – Cyrating, a cybersecurity ratings agency, and Niel Harper, Senior Manager, Next Generation Leaders at the Internet Society – to hear their different perspectives on the forces shaping the Internet’s future.
Cyrating is the first cybersecurity ratings agency anchored in Europe, and helps forward-thinking organizations maximize their cybersecurity performance and investments. It identifies potential for improvement, benchmarks it against industry best practices, and provides standardized cybersecurity metrics. We spoke to François Gratiolet, one of Cyrating’s founders, about the future of a secure and trusted Internet.
(You can read Niel Harper’s interview here).
The Internet Society: Experts predict an increase of frequency and impact of cyberattacks. What form are they likely to take in the next three to five years?
François Gratiolet: We believe cyberattacks will intensify in the next three to five years; targeting both Internet users and the Internet’s underlying infrastructure. User attacks will move from phishing to social media, with Continue reading

#PressForProgress – International Women’s Day 2018 | A Cloudflare & Branch Event
Almost a year ago, I began my journey in the tech industry at a growing company called Cloudflare. I’m a 30-something paralegal and although I didn’t know how to write code (yet), I was highly motivated and ready to crush. I had worked hard for the previous two years, focused on joining a thriving company where I could grow my intelligence, further develop my skill set and work alongside successful professionals. And finally, my hard work paid off; I landed the job at Cloudflare and booked a seat on the rocket ship.
After the initial whirlwind that accompanies this fast-paced field subsided, motivation, inspiration, success, momentum and endurance began to flood my neurons. I loved the inner workings of a successful startup, felt the good and bad of the tech industry, related to and admired the female executives and most importantly, wanted to give something back to the community that adopted me.
