Seconding the other comment, lots of orgs picked .lan and then over the last few years have moved things into the cloud and .lan has become a meaningless soup since half the shit isn’t even on local network. Now it just means “needs a vpn or ztn to talk to”
Luckily my last three orgs finally bought a second domain for private dns. It’s quickly becoming a pattern that myorg.com owns myorg.tech or whatever for private traffic. Domains are cheap as fuck compared to everything else a business spends money on, it’s really silly how many people are using hacks for this
