We can also run various DNS servers, bind and whatnot. 10.10.10.10 or 192.158.255.1 or whatever your local network or even WAN is using.

In the host file we can obviously deal with higher-level of TCP/IP. MAC here of course does not at all refer to Mac as in Apple etc, but to networking since the 60ies or so, an acronoymfor Machine Address C…? etc. Q: is it possible to somehow bind fa20::907:1051:3cc9:0a33 or other, presumably so-called MAC-axresses aka hardware addresees per interface. However, with “ssh CHOSENBONJOURNAME.local” working too, I am ASKING A QUESTION here which seems beyond trivial Google search research. So, with ping CHOSENBONJOURNAME.local specifically on Mac OS X and macOS we can fetch the IP address. (in the environment, using eg “env | grep SSH” on macOS High Sierra, and surely many other platforms for that matter, incl beyond BSD, Darwin, macOS etc ALTHOUGH the Bonjour serviices maybe are not available? On QNAP NAS, for example it is though, under the name avahi, if my memory serves…) Is it possible to use the address given from eg

Ip config macos
