Yeah, that doesn’t work the way you’d like it to:
* The API spec for `gethostname` says nothing about DNS, so it could return something completely unrelated.
* The macOS implementation tries to come up with a reasonable DNS value based on the local network environment, but that means it’s not stable. Back when I used to commute, I’d regularly see one value at work and a different value when I brought my laptop home.
Share and Enjoy
