# Network-hostnamess discovery / Zero-configuration networking /

|
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
