===Systemd===

[[Systemd]] implements both mDNS and LLMNR in <code>systemd-resolved</code>.<!--[[User:Kvng/RTH]]-->

===Link-local IPv4 addresses===

Where no DHCP server is available to assign a host an IP address, the host can select its own [[link-local address]]. ThusUsing a link-local address, hosts can communicate over this link but only locally; Access to other networks and the Internet is not possible. There are some [[Link-local address|link-local IPv4 address]] implementations available:

* Apple Mac OS and MS Windows have supported link-local addresses since 1998.{{citation needed|date=May 2015}} Apple released its open-source implementation in the [[Darwin (operating system)|Darwin]] bootp package.

* [[Avahi (software)|Avahi]] contains an implementation of IPv4LL in the avahi-autoipd tool.

* Zero-Conf IP (zcip).<ref>{{Citation | url = http://zeroconf.sourceforge.net/ | title = zcip | publisher = Source forge}}</ref>

* [[BusyBox]] can embed a simple IPv4LL implementation.

* Stablebox,<ref>{{Citation | url = http://code.google.com/p/stablebox/ | title = Code | contribution = Stable box}}</ref> a fork from Busybox, offers a slightly modified IPv4LL implementation named llad.

* Zeroconf,<ref>{{Citation | url = http://www.progsoc.uts.edu.au/~wildfire/zeroconf/ | title = Zeroconf | publisher = UTS | place = [[Australia|AU]] | access-date = 2005-05-04 | archive-url = https://web.archive.org/web/20050509093846/http://www.progsoc.uts.edu.au/~wildfire/zeroconf/ | archive-date = 2005-05-09 | url-status = dead }}</ref> is a package based on Simple IPv4LL, a shorter implementation by [[Arthur van Hoff]].<ref>{{Citation | url = http://www.zeroconf.org/AVH-IPv4LL.c | publisher = Zero conf | title = AVH IPv4LL | type = C source code}}</ref><!--[[User:Kvng/RTH]]-->

The above implementations are all stand-alone daemons or plugins for [[DHCP]] clients that only deal with link-local IP addresses. Another approach is to include support in new or existing DHCP clients:
