DNS - IPv6
-
But it is.
Because of the trillions of devices in the world requiring an IP Address IPv6 was developed. It could certainly be used in a work environment for the same reasons.
Simplicity in deployment of new devices.

No business or even government is close to the size that IPv4 offers. IPv6 is only larger on the global scale, it doesn't change the size that a business can go to.

Not significantly. Since you can go to any size with IPv4 and can use DHCP the same in either case, you do not gain anything in network deployments from IPv6.
Where IPv6 is important is that it allows you to drop NAT and have public addresses, rather than private, for every host on the network.

Personal preference for myself is that I would not drop NAT if my networks used IPv6 internally. I like that very much as a layer of security for protecting my end-user machines from being exposed directly to all the nasties on the public internet.

NAT does not really add any specific protection. Your firewall does what you describe, not the NAT.
-
Moving away from NAT is a core drive for IPv6. I'm doubtful that NAT devices will even be offered. IPv6 is designed specifically to not have NAT any longer.

I don't think your devices will be any more visible on the internet then they were before. Everything would still go through a firewall or router.

Exactly, still firewalled and blocked from the Internet twice, at a minimum, once at the network edge firewall device and a second time on the per-device firewalls running on every OS.
But it makes the network a lot more powerful. Things like VoIP's RTP protocol and FTP will "just work" instead of having all of the weird NAT traversal issues that they have today. And no more port forwarding, just port opening. Every network can host as many services as it wants instead of having to have crazily complex rules to map many public IPs to many private IPs that have no correlation with one another.

NAT is just address translation doesn't do any blocking your firewall does that. Just because you know where somethings at doesn't mean you get in. It's like saying you are granted access to a building just because you know the address.
We use some NAT internally but I hate it. But when you do lots of mergers it comes with the territory you can't go re-scoping everything and breaking stuff right away.

That's for later?

The rescoping yes, the breaking hopefully not, we get to know the systems and how they are setup more fully (but still possible.)

Otherwise we'd have a rather flat network if we ran IPv6. Compared to the 5 subnets we have.
I also have several subnets. But considering what I know today, I'm looking to move to a single /23 or /22. Because of switches you don't have to worry about 1000 devices being in the same subnet anymore. Sure broadcast storm could bring you down, so you have to fix those quickly, but you'd have to anyway.
I'm not looking forward to reworking my network for a /22 though, ug!
At least I only have around 200 devices. 4/5's are DHCP, but the darn phones is the biggest pain, currently not DHCP. -
I've done the move before, with a little good planning it is surprisingly simple and painless. Normally, at least.

We have so many different subnets it's going to be take us a while to move to IPv6.

Frankly I'd prefer to jump directly to IPv6, but like the rest i have many printers that don't support IPv6. I wonder if my IP phones do? Not that I need to really worry about them.

So glad that we are basically printerless

I would hope so, all of our phones and printer support IPv6.

Yep - main things that have static IPs - Printers, Phones, Server and Switches!!

Dymo label print servers don't support IPv6
