Pretty sure there's a cost to get a /48 from an RIR and probably costs with the various ISPs to route to you. While I'll admit I'm not an IPv6 expert by any means, it doesn't seem like there's a clean path from: "I have a stable internal network addressing scheme under IPv4 that's independent of whatever random ISP I'm using and it sucks I have to use NAT, but it's easy" to "There are enough addresses for everyone to have their own internet, so I'll come up with my own /48 (or get one for free like I had in IPv4) and simply 'connect' to my ISP and it works...no NAT and no port forwarding required...just nice simple firewall rules". -A _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/N42CGCJLJXXLPWVF4NQVSTGYGBFAZXOY/
