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?
Many websites are still IPv4 only, so you won’t be able to access them unless you set up a NAT64 gateway. Some stuff won’t work over NAT64 though.
Most recent hardware should support IPv6, but a lot of IoT devices still don’t. You can put any IoT devices on their own IPv4 network since it’s a security risk to have them on your main network though.
