In the basic networking course I'm co-teaching this semester, I'm doing my best to teach both IPv4 and IPv6 to roughly the same extent.

Presenting dual-stack as default.
Teach the reality you wanna live in. :D

Changed some examples and worksheet questions to IPv6.
Subnetting and longest prefix match are actually way easier this way, at least in my mind.

It's just not so straight-forward to do hand-on examples because our university network still doesn't support IPv6, and it isn't planning to.
"We've got enough IPv4 addresses", they told us… sigh.

But hey, at least we could show our students that IPv6 link-local addresses exist. :3

(That's the addresses starting with fe80::, of which your computer probably also has a few.)

Update on in a basic networking course:

In my tutorials, I discussed IPv6 deployment, and showed a report from June 2018:

"Over 25% of all Internet-connected networks advertise IPv6 connectivity."

"IPv6 has emerged from the “Innovators” and “Early Adoption” stages of deployment, and is now in the “Early Majority” phase."

-> IPv6 is not new. Yes, you [students] have to learn it. Deal with it.

There is an excuses bingo to not deploy it:

Most of these reasons are outdated, like the "I don't want to expose my MAC address" thing, which at least some students had heard about.
Explained privacy extensions. :3


I also showed slides from a presentation at , address policy Working Group:
"Approaching the end of IPv4 - What will the afterlife hold?"

I commented on that like: "Look how sad and gloomy IPv4 is."


Btw. did you make it to v6ops in Bangkok? Specifically Xing Li's presentation on CERNET2. They are running a v6 only production network since 2004. Found it quite interesting.

Starts at about 6:30

@florian Didn't make it there this time, but I'll take a look at the presentation :) Thanks!
