When I connect a device to my router, or if I use a tool like Advanced IP Scanner to look for devices on my network, the found devices are typically listed with and IP and a hostname. My computer running Windows 7 shows up with the name that can be found by typing hostname into cmd.
Some devices, like an embedded device I'm working on, are listed as "unknown" or the IP is simply repeated in the Name column. I can manually edit the etc/hosts file to assign a name for the specific IP of my device and it will show up in the IP Scan results.
My question is, how are these names found by the router/Advanced IP Scanner? What exactly do I need to implement on my device so that it automatically registers a hostname? I already have NetBIOS working, but this does not seem to be related to the hostname.
My embedded device is running the lwIP embedded TCP/IP stack.
