+# Network-hostnamess discovery / Zero-configuration networking / 
+
+http://jaredrobinson.com/blog/upnp-ssdp-mdns-llmnr-etc-on-the-home-network/
+
+ mDNS, NetBIOS, Samba, UPnP, Avahi, LLMNR, WINS,...
+
+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
