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?
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.
