| Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot. It is designed to be |
| lightweight and have a small footprint, suitable for resource constrained routers and firewalls. It has also been widely used |
| for tethering on smartphones and portable hotspots, and to support virtual networking in virtualisation frameworks. |
| Supported platforms include Linux (with glibc and uclibc), Android, *BSD, and Mac OS X. Dnsmasq is included in most |
| Linux distributions and the ports systems of FreeBSD, OpenBSD and NetBSD. Dnsmasq provides full IPv6 support. |
| |
| <P> |
| The DNS subsystem provides a local DNS server for the network, with forwarding of all query types to upstream recursive DNS servers and |
| cacheing of common record types (A, AAAA, CNAME and PTR, also DNSKEY and DS when DNSSEC is enabled). |
| <DIR> |
| <LI>Local DNS names can be defined by reading /etc/hosts, by importing names from the DHCP subsystem, or by configuration of a wide range of useful record types.</LI> |
| <LI>Upstream servers can be configured in a variety of convenient ways, including dynamic configuration as these change on moving upstream network. |
| <LI>Authoritative DNS mode allows local DNS names may be exported to zone in the global DNS. Dnsmasq acts as authoritative server for this zone, and also provides |
| zone transfer to secondaries for the zone, if required.</LI> |
| <LI>DNSSEC validation may be performed on DNS replies from upstream nameservers, providing security against spoofing and cache poisoning.</LI> |
| <LI>Specified sub-domains can be directed to their own upstream DNS servers, making VPN configuration easy.</LI> |
| <LI>Internationalised domain names are supported. |
| </DIR> |
| <P> |
| The DHCP subsystem supports DHCPv4, DHCPv6, BOOTP and PXE. |
| <DIR> |
| <LI> Both static and dynamic DHCP leases are supported, along with stateless mode in DHCPv6.</LI> |
| <LI> The PXE system is a full PXE server, supporting netboot menus and multiple architecture support. It |
| includes proxy-mode, where the PXE system co-operates with another DHCP server.</LI> |
| <LI> There is a built in read-only TFTP server to support netboot.</LI> |
| <LI> Machines which are configured by DHCP have their names automatically |
| included in the DNS and the names can specified by each machine or |
| centrally by associating a name with a MAC address or UID in the dnsmasq |
| configuration file.</LI> |
| </DIR> |
| <P> |
| The Router Advertisement subsystem provides basic autoconfiguration for IPv6 hosts. It can be used stand-alone or in conjunction with DHCPv6. |
| <DIR> |
| <LI> The M and O bits are configurable, to control hosts' use of DHCPv6.</LI> |
| <LI> Router advertisements can include the RDNSS option.</LI> |
| <LI> There is a mode which uses name information from DHCPv4 configuration to provide DNS entries |
| for autoconfigured IPv6 addresses which would otherwise be anonymous.</LI> |
| </DIR> |

| Dnsmasq is mainly written and maintained by Simon Kelley. For most of its life, dnsmasq has been a spare-time project. |
| These days I'm working on it as my main activity. |
| I don't have an employer or anyone who pays me regularly to work on dnsmasq. If you'd like to make |
