We've been hearing about how IPv6 is going to solve all sorts of problems, but what are the issues that we are needing to deal with here?

What is holding up the adoption of IPv6?

And why is it considered so important for regular users (I'm thinking consumer-level here)?

From my understanding, the diminishing pool of IPv4 addresses seems to have been taken care of by CGNAT, which seems to work for most users. However, a disproportionate amount of Geekzone users may want something better.

There's a lot of cloud computing, and many of those servers have public IPs. They're probably running low. Also, CGNAT is a partial solution, it prevents inbound connections, which doesn't matter to most but matters to power users.

IPv6 works fine, on 2degrees and AWS I've been using it for years.

So what is the hold-up with more general adoption?

Are there particular hardware issues that need ironing out, or is the current status of IPv4 not yet critical enough to warrant everyone getting on-board with this?

Ip4 still works, people will only move when they have to. I bet there's a lot of equipment to replace and such.

Gurezaemon: So what is the hold-up with more general adoption?

NAT and later CG-NAT made its need less of an issue. Companies making the investment to move to IPv6 look at it dont see the benefit over staying on IPv4 (so money in this case). And traditionally there was very low IPv6 adoption - so the move to it yielded very little benefits. Especially if you ran a web service - you still needed IPv4 so why bother with both?
