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?
As someone mentioned above, there are some soho devices I have run into that plainly just won’t work with IPv6 even though they claim to and will pull a lease. One or two I have seen just seem to stop working simply by having v6 enabled. Hours of troubleshooting. Its worth making sure someone in internet-land at least claims v6 works on any persistently trouble some devices.
