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.
18:
19: <P>
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: caching 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>
31: <P>
32: The DHCP subsystem supports DHCPv4, DHCPv6, BOOTP and PXE.
33: <DIR>
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
39: included in the DNS and the names can specified by each machine or
40: centrally by associating a name with a MAC address or UID in the dnsmasq
41: configuration file.</LI>
42: </DIR>
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>
