I think one big reason why IPv6 won’t be a thing for a long time is because to the people involved decided to do away with NAT in IPv6.
What a huge mistake.
NAT is obviously a huge crutch but everyone uses it because it’s a dead-simple firewall and makes for dead-simple internal networks. There are NAT-inspired IPv6 analogues but they are not the same.
If NAT with IPv6 was a thing, ISPs could have started shipping routers to customers (as they already do) with IPv6 turned on and we would have already been most of the way to IPv6.
But no, they felt NAT was too hacky and did away with it on a matter of principle.
- WastingMyTime89 3y agoThe issue is not NAT as a firewall. Every routers shipped to customers also come with a firewall and replicating what NAT does by default is dead simple. That’s a red herring. The issue is that migrating to ipv6 meant changing equipments on the backbone and dealing with the change and no operator wanted to bear the cost. It’s getting better now that there is a dearth of ipv4 and people see an immediate benefit.
- Dylan16807 3y agoYou know what's more dead-simple than using NAT as a firewall? A basic firewall without NAT.
- chayleaf 3y agoNAT with IPv6 is a thing, it's trivial to do. I only have a single IPv6 address given to me by my VPN (ISP doesn't support IPv6) and IPv6 masquerading works perfectly fine.
