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?

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.

Having used Azure for a few years now I feel like that might not be entirely on Comcast.

Maybe, but I have yet to see another home ISP with the same problem.
