IPv6 for technicians
During this course you will learn how to use the latest version of the IP protocol, IP version 6 - also called IPv6. The protocol is about 25 years old, so it's about time to get it activated on your servers and networks.
We start the day with some basic history and background on the IP protocol. Next we address IPv6 and the many differences and similarities to IPv4.
During the course, we will address the IPv6 address format, IP header and packet structure, routing tables, stateful (DHCP) and stateless (SLAAC) addressing. We will also look at network traffic live with tcpdump.
In addition, you will also learn about multicast, NDP, which is essential for all IPv6 communication. We also shortly touch DNS around IPv6, ie. PTR records and AAAA records.
Finally, we come to debugging IPv6 networks, including issues with dual-stack configurations (systems with both v4 and v6 configured simultaneously).
Instructor
Thomas Steen Rasmussen works for internet provider BornFiber as Unix administrator/security manager/developer. He also runs his own one-man business – tyktech. He is involved in the DNS censorship service and similar internet activist projects.
Windows users need PuTTY installed.
Agenda
09:00-09:15: Welcome and follow-up on SSH access.There will be exercises during the day. The exercises take place on a virtual server on the Internet which is accessed via SSH. Therefore, please install PuTTY if you are using Windows. It can be downloaded by following the linkat the top of https://putty.org/ Mac and Linux users already have an SSH client.
09:15-10:30: IP protocol, history, and background.
We take a refresher on basic TCP / IP, the history of why IPv6 and get "the basics" in place.
10:30-10:45: Break
10:45-12:15: IPv6 - Differences from IPv4
We review how IPv6 works, differences from IPv4. You will hear more about NDP, SLAAC and many other IPv6 specific terms and concepts – and we will do exercises.
12:15-13:15: Lunch
13:15-14:45: Deeper down in IPv6
We will play with routing between the students' virtual machines and build "our own" small IPv6 internet. Troubleshooting with tcp dump, studying routing tables, etc.
14:45-15:00: Break
15:00-16:00: Troubleshooting IPv6
Last session of the day. We look at common error scenarios and discuss troubleshooting - tips and tricks when things are not working out.
16:00-16:30: Q&A
Target group
This course is for network and system administrators who wish to operate IPv6 servers or networks. The level is slightly rehearsed and rehearsed and requires basic networking skills and knowledge of TCP / IP. If you know what an IP (v4) address and a TCP port is then this is a great start. If you know the difference between a switch and a router, it's even better. The course is in Danish.
