  • Hmm, my understanding was that FQDN means that anyone will resolve the domain to e.g. the same IP address? Which is the case here (unless DNS rebinding mitigations or similar are employed) — but it doesn’t resolve to the same physical host in this case since it’s a private IP. Wikipedia:

    A fully qualified domain name is distinguished by its lack of ambiguity in terms of DNS zone location in the hierarchy of DNS labels: it can be interpreted only in one way.

    In my example, I can run nslookup jellyfin.myexample.com 8.8.8.8 and it resolves to what I expect (a local IP address).

    But IANA network professional by any means, so maybe I’m misusing the term?



  • If you have your own domain name+control over the DNS entries, a cute trick you can use for Jellyfin is to set up a fully qualified DNS entry to point to your local (private) IP address.

    So, you can have jellyfin.example.com point to 192.168.0.100 or similar. Inaccessible to the outside world (assuming you have your servers set up securely, no port forwarding), but local devices can access.

    This is useful if you want to play on e.g. Chromecast/Google TV dongle but don’t want your traffic going over the Internet.

    It’s a silly trick to work around the fact that these devices don’t always query the local DNS server (e.g., your router), so you need something fully qualified — but a private IP on a public DNS record works just fine!













  • My headcanon for The Matrix’s “humans are batteries” is that it’s the machines’ perverse interpretation of this — killing the humans is off the table, and for whatever reason letting them live with no purpose to serve the machines is also disallowed. But giving their lives “meaning” in the form of a shitty (and thermodynamically dubious) “battery” somehow satisfies the rules.

    It’s a very big stretch, I’ll admit…
