My company used .local for EVERYTHING. I took it as normal at the time, until I got into problems with VMWARE products.

Support patiently explained .local is reserved for something else and kindly provided Wikipedia links.

They never responded why they used .local in their docs, trainings, webinars they provided, though :)

Things from docs making it into production is insidious. There were some early Sun docs that referenced a 129.9.0.0/16 network. Some helpful contractor in my locality, specializing in local government work, configured several police, fire, and city governments with that subnet internally back in the 90s. A few of them are still running that way today. I remember running into some oddball behavior with the Teredo adapter in Windows 7 that I traced back to it behaving differently because the PC's IP address didn't fall into RFC1918 space.

Makes me remember the 192.1 addresses that were all over at one place I worked. "Um you know that is a valid internet address right?" "Yeah, but the guy who originally set the systems up was confused about the private address space, used the wrong one and we don't want to break anything so are not going to change it"

Good times.

I’ve worked with hundreds of customers that use .local internal domains and vmware, what issues are you describing?

My impression is that Ballmer IE6 era Microsoft didn't gave a shit about standards.

Is standard you are talking about is Multicast DNS https://www.rfc-editor.org/rfc/rfc6762 from year 2013?
