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?
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.
