13 | Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot. It is designed to be |
14 | lightweight and have a small footprint, suitable for resource constrained routers and firewalls. It has also been widely used | |
15 | for tethering on smartphones and portable hotspots, and to support virtual networking in virtualisation frameworks. | |
16 | Supported platforms include Linux (with glibc and uclibc), Android, *BSD, and Mac OS X. Dnsmasq is included in most | |
17 | Linux distributions and the ports systems of FreeBSD, OpenBSD and NetBSD. Dnsmasq provides full IPv6 support. | |

20 | The DNS subsystem provides a local DNS server for the network, with forwarding of all query types to upstream recursive DNS servers and |
21 | cacheing of common record types (A, AAAA, CNAME and PTR, also DNSKEY and DS when DNSSEC is enabled). | |
22 | <DIR> | |
23 | <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> | |
24 | <LI>Upstream servers can be configured in a variety of convenient ways, including dynamic configuration as these change on moving upstream network. | |
25 | <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 | |
26 | zone transfer to secondaries for the zone, if required.</LI> | |
27 | <LI>DNSSEC validation may be performed on DNS replies from upstream nameservers, providing security against spoofing and cache poisoning.</LI> | |
28 | <LI>Specified sub-domains can be directed to their own upstream DNS servers, making VPN configuration easy.</LI> | |
29 | <LI>Internationalised domain names are supported. | |
30 | </DIR> | |

7e22cf28 | 32 | The DHCP subsystem supports DHCPv4, DHCPv6, BOOTP and PXE. |
9e4abcb5 | 33 | <DIR> |
7e22cf28 SK |
34 | <LI> Both static and dynamic DHCP leases are supported, along with stateless mode in DHCPv6.</LI> |
35 | <LI> The PXE system is a full PXE server, supporting netboot menus and multiple architecture support. It | |
36 | includes proxy-mode, where the PXE system co-operates with another DHCP server.</LI> | |
37 | <LI> There is a built in read-only TFTP server to support netboot.</LI> | |
38 | <LI> Machines which are configured by DHCP have their names automatically | |
26128d27 | 39 | included in the DNS and the names can specified by each machine or |
7e22cf28 SK |
40 | centrally by associating a name with a MAC address or UID in the dnsmasq |
41 | configuration file.</LI> | |

43 | <P> |
44 | The Router Advertisement subsystem provides basic autoconfiguration for IPv6 hosts. It can be used stand-alone or in conjunction with DHCPv6. | |
45 | <DIR> | |
46 | <LI> The M and O bits are configurable, to control hosts' use of DHCPv6.</LI> | |
47 | <LI> Router advertisements can include the RDNSS option.</LI> | |
48 | <LI> There is a mode which uses name information from DHCPv4 configuration to provide DNS entries | |
49 | for autoconfigured IPv6 addresses which would otherwise be anonymous.</LI> | |

82 | Dnsmasq is mainly written and maintained by Simon Kelley. For most of its life, dnsmasq has been a spare-time project. |
83 | These days I'm working on it as my main activity. | |
