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’m a protective relay settings engineer at a contractor for lots of power companies. I’m dipping my toes into my first substation automation project. Getting to design the device native files, IPs, and other networking parts from the drawings package of site and device manuals. It’s all SEL equipment with a gateway at the top and local powerWAN, RTAC, annunciators, and relays below. I live thousands of miles from the site, so local testing would be challenging but probably have to fly or something lol. I have been doing some research on how to emulate this is a lab setting when all you have is the RTAC and some relays. Is this something SCADA engineers have to do sometimes? Like if you need to test a scheme when you can’t build it physically first?
