I would like to know more about this mdns.

In my experience, the following are unreliable, and it's unclear which one is supposed to work under which context:

  • ping hostname
  • ping hostname.local
  • ping hostname.<whatever that local domain thing is called>

While pinging the ipv4 address is reliable; if the device is reachable on the network, it should respond.

    Happy to help.

    You can find more information here: https://en.wikipedia.org/wiki/Multicast_DNS

    You can learn how to configure it here: https://wiki.archlinux.org/title/Avahi

    I see why some people can be confused though. In some distros it needs to be configured. Once you configure it though it should be rock solid.

    There is no reason why an ICMP packet would be more robust than a multicast udp packet.

    The traditional nomenclature is myhostname.local

    Just make sure that the system firewall is configured to allow mdns. That’s the biggest issue. Once you have e that and you have mdns set up it’s good to go.
