    There are no particular address definitions in my /etc/hosts files,
beyond what's provided by the system. I like partcularly the fact that
the desktop address is not resolved when the desktop is not running.
However, the desktop and the laptops are all running the DNSSEC service
avahi-daemon and this might explain why the local DNS server is known.
Didn't find anything on the web about dnssec on Android.
