Quite literally my first thought. Great, but I can’t issue certs against that.
One of the major reasons I have a domain name is so that I can issue certs that just work against any and all devices. For resources on my network. Home or work, some thing.
To folks recommending a private CA, that’s a quick way to some serious frustration. For some arguably good reasons. On some devices I could easily add a CA to, others are annoying or downright bullshit, and yet others are pretty much impossible. Then that last set that’s the most persnickety, guests, where it’d be downright rude!
Being able to issue public certs is easily is great! I don’t use .local much because if it’s worth naming, it’s worth securing.
Is it? Sounds a lot like what I’d hope to hear from someone with his history.
Maybe he learned something. People can change, it’s just really frickin hard for every one of us.
