I do NOT have any primary nor own IP address, and I don't know when will I
get what IP, I can't just put an IP into /etc/hosts - when connecting to
different networks, ONLY IP that I can't get assigned is the localhost -
Of course that would be different if that was my home machine statically
connected to a network there I could use one of private subnets, however In
places I use to go, I get IPs from such ranges.

What is correct then? use random IP and reconfigure notebook whenever it's
used in a network? yah...

It is what I can expect in such case. However, as long as the man page says:
Display the short host name. This is the host name cut at the
people would expext it's the "host name" (as returneg by gethostname) and
not "fqdn" cut, right?
