Why did you choose to write your backend application using IPv6 APIs only instead of higher abstraction network libraries that support both v4 and v6?

Good question - It's not the APIs that are the issue, it's the actual IPv6 addresses in the packets on the wire that we need. All of our remote devices (typically on the order of 5 million+ for larger customers) have IPv6 addresses. We can use tunnel routers to get the traffic over IPv4 networks to the destination, but the applications themselves are addressing the devices with IPv6 addresses - which means, at least…

Oh wow. I dunno what you're doing where you have customers with 5M devices but that definitely sounds like a very good reason to want to get on IPv6!

Medical devices of some kind? Just guessing.

What product are you building where you can avoid needing public IPv4 addresses considering that the vast majority of the people on the internet still use IPv4? It seems like you'll still need both for many years.

Often you only need one public IPv4 address and thus it doesn't really matter what it costs.

Yes, I agree with you. Which again makes me wonder why djsumdog considers full IPv6 support so critical. Except for very unusual businesses it doesn't seem to make sense.

Couple different classes of customers - utilities are the existing (Electric/Gas/Water meters) and IoT (Sensors, Street Lights, Parking) are the up and coming.

Both of them lend themselves well to mesh networking application, and mesh networks, in which any one of the 5mm+ deployed devices might appear in any one of the 10,000+ network segments, and in which we just want to concatenate the MAC address and Network segment to get a network address (basically SLAAC) - really makes IPv6 a pretty good fit.

Neat! Sounds like a fun problem to work on.
