I was using adsb.fi for aircraft tracking, but tonight I was pointed to adsb.lol which has some extra features and works on my #ipv6 only network.

@train Yeah I need to actually sit down and write a post about what I'm doing. It only really came into focus the last couple days, but now that it's up I think I'm pretty happy with it.

tl;dr: #IPv6 to the max

#monitoring #ipv6 #ipv4

lol - the first website on the internet https://info.cern.ch/ supports #ipv6 but https://github.com doesn't. Embarrassing!

Dabbled with enabling #IPv6 on my #cilium based #k3s cluster this morning. Seems that it /is/ possible to enable without a full cluster/node rebuild*.

Mostly went fine, prefix, prefix mask, masq set to off. After poking a couple of the Cilium Pods new Pods got an IPv6 addr. ...but couldn't ping anything. Traffic made it out based on what Hubble was showing, but not the reverse.

Enabled v6 masquerading, and it all started to work, yay. Suspect I need to try setting up a static route on my router for this to work.

I have a couple pods w/ quirky networking so they got unhappy. v6 IP, dns query replying w/ AAAA but no dice as they really only have v4 connectivity.

Back off for now but promising that it could work.

*.spec.PodCIDR(s) are immutable on v1.Node resources, but cilium in it's default configuration doesn't get it's PodCIDR from there in the default config.

"If you have a website and it's not v6 reachable, it's not on the Internet."

#ThrowbackThursday #IPv6

Anyone here running a SDN in Proxmox 9.1 with IPv6 enabled? Preferably without NAT, but I think that's currently not possible?

IPv4 worked fine within minutes, but v6 I can't for the life of me figure out how to get it going.

We do have a /64 Subnet, so I should be able to assign IPs from that via SDN I guess? But the Docs haven't been helpful so far :/

#Proxmox #SDN #IPv6

I heard Bambit (Bamberg’s municipal ISP) supports IPv6 now

Can someone confirm?

#ipv6

Where are my #ipv6 experts at?

My #guixrouter is having problems where when I restart its networking, it can respond to neighbor discovery, but after some time... it stops receiving neighbor discovery requests (they don't appear in tcpdumps). I think this must be either something to do with my switch or something to do with the linux bridge on the proxmox host... why would this happen? I can see the ndp snooping entry disappears on switch, but it happens even if ndp snooping is off

@doachs ?

Time for another very irregular regular update on #IPv6 compared to #IPv4 usage on a dual stacked college network.

As you can see from the graph, for most of the past 24 hours, incoming IPv6 traffic is significantly higher than incoming IPv4 traffic. This has been the case for many years now.

@to3k , "We are lazy and don’t want to mess around with IPv6 problems, so we choose the IPv4 option even though it’s 74 cents more expensive" - have you had any problems with #IPv6?! I remember even in 2011 it just worked in Hetzner.

Nice! NAT64 in action, My IPv6-only jail can successfully talk with Github. No tayga, just the new "af-to" feature, that the "pf" firewall got in 15.0-RELEASE:

pass in quick on bastille0 inet6 from $jail_net to 64:ff9b::/96 \
af-to inet from ($ext_if) keep state

This is genuinly nice! 🙂

@amy My rural ISP asked me today, if I even have a viable use case for #ipv6 As it would be easier for them to roll me back to ipv4 only to fix some DSL Sync issues.

@goetz Not a feature request, a bug report stating that #IPv6 is not working.

If you are using an online shop and the checkout requires PayPal, Stripe or else, please make shure to send a Feature Request to the online shop to ask their payment processor for #IPv6 support.

Happy Eyeballs has been a disaster for #IPv6 transition. We've trained a whole generation of admins that it's OK if your v6 doesn't work, the client will just fall back to IPv4. What if the client has no legacy connectivity to fall back on? That was (and still is) the goal.

If you believe that AI is inevitable but #IPv6 is not, well, you're probably not even reading this since we don't live in the same reality.

In light of ntfy.sh becoming the latest den of slop code, I have stopped using it.

For UnifiedPush I am now using Conversations. There's something ironic about one messaging client (Element X) using another for its notifications. Now we need to get #IPv6 enabled on up.conversations.im.

Last night instead of going to bed I forgot about daylight saving time and added a statically defined #ipv6 #wireguard mesh between my #homelab servers.

Now I can use that instead of #tailscale for the secure data plane. Tailscale is great and I'll probably keep it for the management plane. The way it aggressively idles connections combined with the first packet seemingly always hitting a DERP server makes stuff feel a lot slower than it should.

Später, eher durch Zufall, dann das hier:
Change Ollama server to use IPv6 addressing by running export OLLAMA_HOST=":11434" before starting the Ollama server. Note this IPv6 support requires Ollama version 0.0.20 or newer.

#ipv6

Liebes @BMDS ,

warum ist es so schwierig, den Betrieb dieser Webseiten sicherzustellen?

#ipv6

Since I recently moved my primary DNS to PowerDNS, I realized I can expose its API to my OpnSense and finally get support for dynamic DNS for IPv6 with host-part replacement. Now I can choose if I want to expose things natively on IPv6 PD addresses and proxied on IPv4, or proxied on both AFs, rather than proxying everything. Particularly useful for non-HTTP services.

The bits and pieces were mostly there before, but the stars never aligned for me. RFC2136 would support it, but the plugin was deprecated and never had the prefix replacement feature. ddclient plugin with the nsupdate mode in theory might have worked, but OpnSense doesn't include the nsupdate binary so that was a non-starter. Otherwise it only supports proprietary/custom HTTP APIs. Caddy does have a module for rfc2136, but the binaries in the OpnSense plugin don't include it, and host replacement isn't supported anyway. I suppose I could have written something and stuck it in a container somewhere but eh...

Happy to finally have a decent answer that doesn't depend on a 3rd party service's API.

An online friend of mine and me were having a chill conversation about DNS, IPv6 and what not. We went down memory lane how and when we actually met. Also Freifunk got an honorable mention.

That was fun. I opened a ticket to close an account I wasn't using. They responded with the classic "What could we have done to keep your business?" I basically called them out on never having an ETA on #ipv6 every time I asked despite it being a purchasing requirement for me. They completed the account closure without further comment. I doubt it will make a difference, but they do now have a record of losing at least one potential customer because they didn't keep up.
