alt Hacker NewsNot surprised. They used to have training material incentivizing professionals to use .local as TLD for Active Directory realms. Thats a reserved domain for Multicast DNS.
Working on Linux automation systems we would need to make sure to disable anything related to Avahi in our images otherwise name resolution would fail for some customers.

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 :)
Usage of .local for AD predated mDNS. That advice stopped with the advent of mDNS in favor of 'corp.<registered_domain>.<tld>'.
Haven't they been telling people to do that since before it became reserved? If so, the problem is more that you can't "reserve" something that's already in wide use, and mdns should've used something like .mdns.
It's like when .dev became a gTLD, knowingly breaking a bunch of setups for a mix of vanity and a cash grab. Obviously dropped the ball on the engineering side.
