with IPv6 deployment reaching 80%+ in many places, we can probably remove IPv4 support from FreeBSD 17.0.

i'm sure this won't cause any issues for users because people constantly say that FreeBSD users are super evolved and up-to-date with the latest technologies, unlike those awful Linux users.

The most recent encounter is https://adsb.fi/

> These endpoints are accessible for people contributing to adsb.fi by hosting a receiver. Your feeder IP address is automatically given access.

src: https://github.com/adsbfi/opendata/blob/main/README.md

adsb.fi is fronted by Cloudflare, so they could enable #IPv6 relatively easily, but they would have to revamp their feeder authentication.

The first such system I encountered was https://tgif.network/ , a #hamradio DMR network. Users would log in to the website and their hotspots would be shown based on whether they were connected from the same IPv4 address. They've moved away from this mechanism as all hotspots are now credential authenticated as well. Unfortunately, even with this change, the underlying software does not have any #IPv6 support.

I'm still running into websites that grant access based on your IPv4 address, presuming some other authenticated device coming from the same network. This image clearly has not clicked with the admins of these systems yet.

A black box with a bundle of cables labeled "1000 Users" coming in one side. Some of the smaller cables are labeled "OAK USR29" "SFO USR1" "SJC USR2" "SEA USR13" and "BAD GUY". The box is labeled "CGN NAT Network Address Translation". Exiting the other side of the box is a lone cable labeled "Single IPv4". The box contains a swivel arm meter with unit "Capacity" graded from 0-100%. The needle is very close to 100%.

ChatGPT was released a mere two years ago and people will not shut up about it.

I didn't have the script under version control, but by virtue of my having migrated it across machines I had enough breadcrumbs to re-create some of the version history. If you'd like to see what I've been working on: https://git.home.nivex.net/nivex/jool-clat

I got down a rabbit hole this evening of tweaking my Jool CLAT script. More parameter checks, support for the internal bridge I use for my VMs, and a proper wait loop for SLAAC to finish when determining the CLAT v6 address. It leverages jq to parse iproute2 JSON output to make things easier.

i know have a little Gemini pod in the Geminispace :-) Of course, hosted on a FreeBSD server and securely running inside a Jail and with native IPv6.

gemini://gemini.hofstede.it

More content there will follow 🙂

Gemini is a lightweight, privacy-focused alternative to the web.

To browse Geminispace, you'll need a dedicated Gemini client (like a browser but simpler).

Need to setup a new network within the next 1-2 years. Thinking about #ipv6 only because I would easy get a /48 there. But till now found no solution to break the Mail, Asterisk, Matrix, Jitsi #IPv4 connectivity. Still so much IPv4 only setupus out there.

This sounds like an awful question:

Can I "port forward" an ipv6addr:port pair to an internal ipv4 address?
#Homelab #Networking #IPv6 #Mikrotik

Ok so after a bunch of searching for a good tool to track down what is running on the network I settled on:

* Security onion ingesting NetFlows from the router. This catches all traffic that crosses subnets. Traffic within the subnets isn't as much of a concern at this stage.
* Nmap plus a stylesheet I found was able to generate a pretty digestible html doc enumerating ports and hosts

From those sources I can pretty easily setup sensible firewalls at the router level, and potentially at the host level as well. After that I can work on intra-kubernetes traffic rules.

Also I used some of the initial data to sort hosts a little better and cleanup DHCP/static DNS entries

Lastly I'm going to back away slowly from ipv6 again. I did learn a bit and made some progress but getting that cluster properly talking dual stack is less of a priority at the moment I think?

AWS Site-to-Site VPN now supports IPv6 on the outside IPs

If I use openresolv in place of resolvconf I don't run into the timing issue, but it has no notion of interface-order so it gleefully puts IPv4 resolvers ahead of #IPv6 with no apparent way to change this.

I love the power of bash scripting

Being thankful is important, esp. when you use opensource software.

I'm thankful to the coder(s) of gping a command which sends a nice graphical output in *sh when you invoke it of the ping reponses of your favourite server

In the same line I again want to thank the coder(s) of httping which can send you ping responses in an awsome way

I had spoken about httping before

Thank you all

The image shows a computer screen with a terminal window open, displaying network latency data. The terminal window is titled "mocp" and shows a ping test to the server "ftp.sunet.se" with various latency measurements in milliseconds, such as 277.41ms, 262.225ms, and 247.04ms. The background of the terminal window features a green digital rain effect, which is a visual representation of data being processed. Below the terminal window, there is a timestamp indicating the time as 11:49:09, and a video player interface is visible at the bottom, showing a timestamp of 11:49:24. The video player is paused, and the video displays a rural scene with a structure resembling a gazebo and trees. The overall color scheme of the image is dark, with green text and graphics contrasting against a black background.

The image shows a detailed network performance analysis tool interface, likely from a command-line application. The interface displays various metrics and graphs related to network activity. At the top, there are columns labeled "latest," "mocp," "avg," "max," "sd," "mc-a," "cur," "cafe," and "RemAD," with data such as "resolve," "connect," "ssl," "send," "request," "close," and "total" presented in numerical values. The graph at the bottom shows a timeline of HTTP responses, with green bars indicating successful responses (200 OK) and red bars for failed attempts. The HTTP response code is "200 OK," and the SSL fingerprint is "n/a." The "Last-Modified" timestamp is "Thu, 10 Apr 2025 15:18:21 GMT," and the "Expires" timestamp is "Tue, 23 Sep 2025 15:08:53 GMT." The "Content-Type" is "text/html; charset=UTF-8." The interface also shows the run time, which is "2025/09/23 12:07:33.408," and the total number of requests, "4341751." The graph indicates a high frequency of successful responses, with a few failed attempts. Provided by @altbot, generated privately and locally using Ovis2-8B 🌱 Energy used: 0.903 Wh

Ok so more IPv6 thoughts:

I was thinking a bit more about the idea to move the dnsmasq service onto the router:

So the entire reason for switching to dnsmasq was because it creates DNS entries for DHCP clients, and it even can assign a different subdomain per subnet.

However, there was something I had yet to get functional: mapping IPv6 to those same DNS names.

I'm not even sure how that is possible! Certainly not with dnsmasq because I don't have it handling anything? Or maybe there is some stateless DHCP option?

Which got me to thinking that maybe it is possible with Mikrotik's scripting?

On a related note I saw a script to update IPv6 prefix if that updates which looks super useful and might put me at ease. I could use ULAs for internal traffic and have that prefix updater script update firewalls if anything changes.

#Homelab #Networking #IPv6 #Mikrotik

Cooking or cooked: link shortening edition

URLs are compressed but rather than a path they become a subdomain.

Server-side for creation:

A DNS entry is created with a unique, globally addressable IP address from the host's delegated v6 /64, and adds that IP to the main interface.

Client-wise:

The dynamic subdomain is delegated out to the host. The host DNS server responds with the unique IP for that link shortening. When it receives HTTP for that IP it responds with the usual redirect/301 to the full address.
