It is designed to provide DNS and, optionally, DHCP, to a + small network. It can serve the names of local machines which are + not in the global DNS. The DHCP server integrates with the DNS + server and allows machines with DHCP-allocated addresses + to appear in the DNS with names configured either in each host or + in a central configuration file. Dnsmasq supports static and dynamic + DHCP leases and BOOTP/TFTP/PXE for network booting of diskless machines. +<P> + Dnsmasq is targeted at home networks using NAT and +connected to the internet via a modem, cable-modem or ADSL +connection but would be a good choice for any smallish network (up to +1000 clients is known to work) where low +resource use and ease of configuration are important. +<P> +Supported platforms include Linux (with glibc and uclibc), *BSD, +Solaris and Mac OS X. +Dnsmasq is included in at least the following Linux distributions: +Gentoo, Debian, Slackware, Suse, Fedora, +Smoothwall, IP-Cop, floppyfw, Firebox, LEAF, Freesco, fli4l, +CoyoteLinux, Endian Firewall and +Clarkconnect. It is also available as FreeBSD, OpenBSD and NetBSD ports and is used in +Linksys wireless routers (dd-wrt, openwrt and the stock firmware) and the m0n0wall project. +<P> +Dnsmasq provides the following features: +<DIR> + +<LI> +The DNS configuration of machines behind the firewall is simple and +doesn't depend on the details of the ISP's dns servers +<LI> +Clients which try to do DNS lookups while a modem link to the +internet is down will time out immediately. +</LI> +<LI> +Dnsmasq will serve names from the /etc/hosts file on the firewall +machine: If the names of local machines are there, then they can all +be addressed without having to maintain /etc/hosts on each machine. +</LI> +<LI> +The integrated DHCP server supports static and dynamic DHCP leases and +multiple networks and IP ranges. It works across BOOTP relays and +supports DHCP options including RFC3397 DNS search lists. +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 in the dnsmasq +config file. +</LI> +<LI> +Dnsmasq caches internet addresses (A records and AAAA records) and address-to-name +mappings (PTR records), reducing the load on upstream servers and +improving performance (especially on modem connections). +</LI> +<LI> +Dnsmasq can be configured to automatically pick up the addresses of +its upstream nameservers from ppp or dhcp configuration. It will +automatically reload this information if it changes. This facility +will be of particular interest to maintainers of Linux firewall +distributions since it allows dns configuration to be made automatic. +</LI> +<LI> +On IPv6-enabled boxes, dnsmasq can both talk to upstream servers via IPv6 +and offer DNS service via IPv6. On dual-stack (IPv4 and IPv6) boxes it talks +both protocols and can even act as IPv6-to-IPv4 or IPv4-to-IPv6 forwarder. +</LI> +<LI> +Dnsmasq can be configured to send queries for certain domains to +upstream servers handling only those domains. This makes integration +with private DNS systems easy. +</LI> +<LI> +Dnsmasq supports MX and SRV records and can be configured to return MX records +for any or all local machines. +</LI> +</DIR> + +<H2>Download.</H2> + +<A HREF="http://www.thekelleys.org.uk/dnsmasq/"> Download</A> dnsmasq here. +The tarball includes this documentation, source, and manpage. +There is also a <A HREF="CHANGELOG"> CHANGELOG</A> and a <A HREF="FAQ">FAQ</A>. +Dnsmasq is part of the Debian distribution, it can be downloaded from +<A HREF="http://ftp.debian.org/debian/pool/main/d/dnsmasq/"> here</A> or installed using <TT>apt</TT>. + +<H2>Links.</H2> +Damien Raude-Morvan has an article in French at <A HREF="http://www.drazzib.com/docs-dnsmasq.html">http://www.drazzib.com/docs-dnsmasq.html</A> +There is a good article about dnsmasq at <A +HREF="http://www.enterprisenetworkingplanet.com/netos/article.php/3377351">http://www.enterprisenetworkingplanet.com/netos/article.php/3377351</A> +and another at <A +HREF="http://www.linux.com/articles/149040">http://www.linux.com/articles/149040</A> +and Ilya Evseev has an article in Russian about dnsmasq to be found at +<A HREF="http://ilya-evseev.narod.ru/articles/dnsmasq"> +http://ilya-evseev.narod.ru/articles/dnsmasq</A>.
