I know for many of us every day is selfhosting day, but I liked the alliteration. Or do you have fixed dates for maintenance and tinkering?

Let us know what you set up lately, what kind of problems you currently think about or are running into, what new device you added to your homelab or what interesting service or article you found.

This post is proudly sent from my very own Lemmy instance that runs at my homeserver since about ten days. So far, it's been a very nice endeavor.

I finally got IPv6 working in Docker Swarm...by moving from Docker Swarm to regular Docker.

Traefik now properly gets IPv6 addresses and forwards them to the backend.

What's the big benefit of moving to IPv6 for a LAN? Just wondering if there is any other benefits over addresses? My unifi kit can convert us to IPv6 but I'm hesitant without knowing what devices it will break.

Copying from an older comment of mine:

IPv6 is pretty much identical to IPv4 in terms of functionality.

The biggest difference is that there is no more need for NAT with IPv6 because of the sheer amount of IPv6 addresses available. Every device in an IPv6 network gets their own public IP.

For example: I get 1 public IPv4 address from my ISP but 4,722,366,482,869,645,213,696 IPv6 addresses. That’s a number I can’t even pronounce and it’s just for me.

There are a few advantages that this brings:

  • Any client in the network can get a fresh IP every day to reduce tracking
  • It is pretty much impossible to run a full network scan on this amount of IP addresses
  • Every device can expose their own service on their own IP (For example: You can run multiple web servers on the same port without a reverse proxy or multiple people can host their own game server on the same port)

There are some more smaller changes that improve performance compared to IPv4, but it’s minimal.

My unifi kit can convert us to IPv6 but I’m hesitant without knowing what devices it will break.

You don't usually "convert" to IPv6 but run in dual stack, with both IPv4 and IPv6 working simultaneously. Make sure your ISP supports IPv6 first, there is little use to only run IPv6 internally.

Very helpful thanks for digging out up for me.
