IPv6 for Luddites


Andrew (aka mcnalu) recently triggered Beni by saying that he turns off IPv6 in order to get devices working on his home network. In this show Beni educates Andrew the Luddite and explains why moving from IPv4 to IPv6 is a good idea. They also explore how IPv6 can be used in a world where ISPs and devices do not all support it and what tools, tips and tricks are available during this rather long transitional phase to the newish (like 30 years old, a blink of an eye in IT) protocol.

Great intro to IPv6

Did I want to be reminded that I am old enough to remember when IPv6 was first introduced? No, but loved the conversation, and does have me wanting to try out IPv6 on my home network. A nice test for my ASUS router running DD-WRT.

Please post your talk

I hope you get to present at the BSD conference you mentioned.
But you can always to a HPR show about using OpenBSD as a router for a IPv6 only home network

IPv6 on HPR

dig -t AAAA +short hackerpublicradio.org

looks like the webmasters should listen to this show

I opened a bug, you can help fix it.

Hi wheresalice,

I have opened a bug(https://repo.anhonesthost.net/HPR/hpr_hub/issues/97) to track the issue.

We are a volunteer service so please consider helping us out with resolving it. Please read the developer information(https://repo.anhonesthost.net/HPR/hpr_documentation/src/branch/main/developer_information.md) before you decide to contribute.

There may be additional costs associated with this, so we need to check. Josh pays for the entire HPR website hosting and if anyone wants to support him you can by going to https://anhonesthost.com(https://anhonesthost.com). We need to move hosting location soon and I have asked Josh if we have ipv6 support there.

You can also help by adding some IPv6 shows to our Networking series. You can contribute your own shows about IPv6(https://hackerpublicradio.org/about.html#so_you_want_to_record_a_podcast), as you clearly have some experience debugging dns at least ;-).

If you prefer you can cohost with Beni who is looking for people to help with sitting in for his shows.

I've updated the Requested Topics(https://repo.anhonesthost.net/HPR/hpr_documentation/src/branch/main/requested_topics) page to include some more IPv6 requests.

Feel free to do overview shows, but also deep dives eg, into the structure of the packets.

Fantastic show - thank you

I think your explanation of ipv6 was very clear and understandable. My home network is ipv4, even though I have an ipv6 ready ISP, and a static ipv6 address (range, as I now understand!). I feel like the time has come...
I will be listening to the show again, in order to learn enough to get started. I don't know if it would be practically possible, but we could make a show together setting everything up on my home network? What do you think? We would have to find a way where you don't have to do much to make it happen (i.e. - I am _not_ scouting for free consulting)!
Thanks for a great episode - Paul

I was surprised to find that my ISP offers IPv6

Hi Beni,

This was a great show! It really alerted me to how complacent I have become with my networking. I checked my ISP (Zen in the UK) and they offer IPv6 on request.

I need to teach myself more about the details though. Of course, if someone were to make some shows on this subject on HPR, I'd be well on the way :-)

I would like to set up VLANs on my network so I can isolate gadgets like my EV charger and the monitoring thing Octopus Energy sent me that apparently needs to be on my WiFi. I also want to isolate any IoT devices I install.

I also need to know how to allocate fixed IPv6 addresses for my Raspberry Pis, and so on and so forth.

A long time ago I used to be in charge of networking where I worked, but that was when we ran X.25, so my brain needs a lot of updates...

Dave
