! 15: Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP
! 16: server. It is designed to provide DNS and, optionally, DHCP, to a
! 17: small network. It can serve the names of local machines which are
! 18: not in the global DNS. The DHCP server integrates with the DNS
! 19: server and allows machines with DHCP-allocated addresses
! 20: to appear in the DNS with names configured either in each host or
! 21: in a central configuration file. Dnsmasq supports static and dynamic
! 22: DHCP leases and BOOTP/TFTP/PXE for network booting of diskless machines.
! 23: <P>
! 24: Dnsmasq is targeted at home networks using NAT and
! 25: connected to the internet via a modem, cable-modem or ADSL
! 26: connection but would be a good choice for any smallish network (up to
! 27: 1000 clients is known to work) where low
! 28: resource use and ease of configuration are important.
! 29: <P>
! 30: Supported platforms include Linux (with glibc and uclibc), Android, *BSD,
! 31: Solaris and Mac OS X.
! 32: Dnsmasq is included in at least the following Linux distributions:
! 33: Gentoo, Debian, Slackware, Suse, Fedora,
! 34: Smoothwall, IP-Cop, floppyfw, Firebox, LEAF, Freesco, fli4l,
! 35: CoyoteLinux, Endian Firewall and
! 36: Clarkconnect. It is also available as FreeBSD, OpenBSD and NetBSD ports and is used in
! 37: Linksys wireless routers (dd-wrt, openwrt and the stock firmware) and the m0n0wall project.
! 38: <P>
! 39: Dnsmasq provides the following features:
! 40: <DIR>
! 41:
! 42: <LI>
! 43: The DNS configuration of machines behind the firewall is simple and
! 44: doesn't depend on the details of the ISP's dns servers
! 45: <LI>
! 46: Clients which try to do DNS lookups while a modem link to the
! 47: internet is down will time out immediately.
! 48: </LI>
! 49: <LI>
! 50: Dnsmasq will serve names from the /etc/hosts file on the firewall
! 51: machine: If the names of local machines are there, then they can all
! 52: be addressed without having to maintain /etc/hosts on each machine.
! 53: </LI>
! 54: <LI>
! 55: The integrated DHCP server supports static and dynamic DHCP leases and
! 56: multiple networks and IP ranges. It works across BOOTP relays and
! 57: supports DHCP options including RFC3397 DNS search lists.
! 58: Machines which are configured by DHCP have their names automatically
! 59: included in the DNS and the names can specified by each machine or
! 60: centrally by associating a name with a MAC address in the dnsmasq
! 61: config file.
! 62: </LI>
! 63: <LI>
! 64: Dnsmasq caches internet addresses (A records and AAAA records) and address-to-name
! 65: mappings (PTR records), reducing the load on upstream servers and
! 66: improving performance (especially on modem connections).
! 67: </LI>
! 68: <LI>
! 69: Dnsmasq can be configured to automatically pick up the addresses of
! 70: its upstream nameservers from ppp or dhcp configuration. It will
! 71: automatically reload this information if it changes. This facility
! 72: will be of particular interest to maintainers of Linux firewall
! 73: distributions since it allows dns configuration to be made automatic.
! 74: </LI>
! 75: <LI>
! 76: On IPv6-enabled boxes, dnsmasq can both talk to upstream servers via IPv6
! 77: and offer DNS service via IPv6. On dual-stack (IPv4 and IPv6) boxes it talks
! 78: both protocols and can even act as IPv6-to-IPv4 or IPv4-to-IPv6 forwarder.
! 79: </LI>
! 80: <LI>
! 81: Dnsmasq can be configured to send queries for certain domains to
! 82: upstream servers handling only those domains. This makes integration
! 83: with private DNS systems easy.
! 84: </LI>
! 85: <LI>
! 86: Dnsmasq supports MX and SRV records and can be configured to return MX records
! 87: for any or all local machines.
