Is anybody using only IPv6 in their home lab? I keep running into weird problems where some services use only IPv6 and are “invisible” to everyone (I’m looking at you, Java!) I end up disabling IPv6 to force everything to the same protocol, but I started wondering, “why not disable IPv4 instead?” I’d have half as many firewall rules, routes and configurations. What are the risks?
Unfortunately, going IPv6 only is a pain since so much stuff is still reliant on IPv4.
I avoid ipv6 as much as possible.
Why?
It fucking sucks. I’ve been hearing about it for twenty plus years and it’s caused me more problems than it’s solved. Comcast DNS routinely breaks connecting to niche sites like Microsoft 365 😑. Its overly complicated and easier to screw up. If turning off IPv6 would stop solving more problems maybe I’d give it a better go, but as it stands it’s like the USB-c standard of a clusterfuck of poor design and implementation in practice.
I’m sorry you’ve had a poor experience, but I’ve had nothing but smooth sailing since my ISP gave me a /64. I had to re-learn most of what I knew and unlearn a few bad v4 habits, but v6 has solved issues that I was tired of dealing with. I can’t imagine what you’re doing to think it’s more complicated and easier to screw up than v4.
If DNS wouldn’t constantly break I’d be more open to learning. Right now what’s the point?
Lets say you have a bunch of self hosted servers. How are you tracking their ips on ipv6? Are you able to type the ip off the top of your head? I feel like its very simple with ipv4.
Are you binding services to specific addresses? Normally if you bind your service to :: it will receive IPv4 connections using ::ffff:x.x.x.x addresses.
I went IPv6-only for everything internal. The only thing that’s dual stack is the wireguard server running on the gateway. I haven’t run into any issues, mostly because my Linux distro’s package repository has many IPv6-compatible mirrors (enabled by default). For anything not in the distro’s repos, I build from source and package them up into RPMs myself, so as a side-effect, I don’t have to deal with eg. Github not supporting IPv6.
Even things with generally crappy firmware, like the APC UPS management card, Supermicro & ASRock IPMI management interfaces, etc. have worked fine in an IPv6-only setup for me.

When troubleshooting some network shares and other issues the remedy was disable ipv6 lol. i’m not familiar with ipv6 enough to know the pros other than more IP addresses available, but since its all on mu LAN i have no need for ipv6
