What a mess

Seems LLMNR is reliable and widly available everywhere for hostname resolution. Even when wiki says its being phased out by microsoft.

Tested with wireshark. Pinging for a nonexisting hostname mans LLMNR broadcast to every device on network is send asking who is that hostname. Works same when pinging from archlinux or pinging from win8.1

TCP vs UDP
