Just my perspective as a controls (SCADA engineer):
I work for a large power company. We have close to 100 sites, each with hundreds of IP devices, and have never had a problem with ipv4. Especially when im out in the field I love being able to check IPs, calculate gateways, etc at a glance. Ipv6 is just completely freaking unreadable.
I see the value of outward-facing ipv6 devices (i.e. devices on the internet), considering we are out of ipv4s. But I don’t see why we have to convert private networks to ipv6. Put more bluntly: at least industry, it just isn’t gonna happen for decades (if it ever does). Unless you need more IPs it’s just worse to work with. And there’s a huge amount of inertia- got one singular device that doesn’t talk ipv6 at a given generation site? What are you supposed to do?
I was going to say, my friend has to maintain some fucking DOS systems because their ancient embroidery machines only want to talk to software as old as they are, over connections as old as they are.
If you set up your DNS correctly then you don’t even need the IPs. Just give devices unique, human-readable names and maybe do separate sub-domains for each site or something.
Oh, now that you mention it I’ve never tried to map a static DNS entry to a device without DNS. Welp, time to get thousands of raspberry pi’s to act as IP KVMs!

90% of industrial devices are still 100 Mbit/s.
I mean that’s of the ethenet capable ones… a huge chunk are still serial

You’ll be lucky if you find ethernet on them. RJ45 serial is still pretty common nowadays

For that to work industrial devices have to support DNS in the first place…
