The xllmnrd project produces an open-source IPv6 LLMNR responder daemon (a.k.a. llmnrd) for GNU/Linux and other POSIX-based operating systems in order to improve interoperability with Microsoft Windows on a small or home network.

xllmnrd is an IPv6 LLMNR responder daemon for GNU/Linux operating systems. It allows Microsoft Windows clients to get the IPv6 addresses of a server on the same local network without any DNS configuration and effectively supplements IPv4-only NetBIOS name resolution provided by Samba.

The latest official release of xllmnrd is version 2.0 published on July 26, 2014.
