Apple took over port 5000 in the latest macOS

What is so special about that port? Is it the default of a framework?

  It’s used in Docker often. I can see it being in that sub for that reason.

  Default port for the Flask python web framework, but the poster was complaining because it's the port they use for something in production. Seems like a silly complaint honestly.

    They specifically said they aren't using that in production

ITT: Squatters taking up residence on an IANA reserved port complain that other, wealthier squatters are now also trespassing on the real owner's turf.

  Ironically the apple use aligns much more with the 'official desgnation' (UPNP) than all the other uses that people are complaining about (dev web servers).

If only there was something that broadcast the availability of services including the port they're on...

  Some kind of a … network map? :)

    Some sort of way to say “hello”.

      Maybe we could jazz it up a little by using a foreign language in the name. Europe is such a historic place, perhaps one of their languages: "Guten Tag", "Hola" or maybe even "Goddag"

One of the comments there: "Just did a bit more digging, and IANA actually assigns port 5000 to "commplex-main" - so really any other service that's using that port is violating the official assignment. Based on a quick search of what commplex-main is, it's related to UPnP for network device discoverability. I'm not sure exactly what the AirPlay Receiver service does, but I get the gist that it probably does fit somewhere into the scope of UPnP-related features. At the very least, it's probably a far more accurate usage of port 5000 than some random dev servers." So looks like they are actually IANA-compliant. Baseless rant.

  Yeah but apple said they will do no evil and this is doing evil /s

  Also in the same thread: it had been previously used in Win XP for SSDP, and (directly below) it has been used around the same time in early OSX for mDNSResponder (Bonjour/Rendezvous related). So, yes, stick to 8080 and friends. There is a reason for this.

  All of this aside, ports are cheap. Over 64 thousand of them to use, though some are ephemeral (lol)
