Dnsmasq is a free software [DNS] forwarder and [DHCP] server for small networks.
 * It is considered to be easily configured, with low system resource usage.

Dnsmasq supports [Linux], [BSDs], [Android] and [OS X], and is included in most Linux distributions.

Features
The DHCP server supports static and dynamic DHCP leases and multiple networks and IP address ranges.
 * The DHCP server integrates with the DNS server and allows local machines with DHCP-allocated addresses to appear in the DNS.

Dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance,
 * and can be configured to automatically pick up the addresses of its upstream servers.

Dnsmasq supports modern Internet standards such as [IPv6] and [DNSSEC], network booting with support
 * for [BOOTP], [PXE] and [TFTP] and also [Lua] scripting.

Some Internet service-providers rewrite the NXDOMAIN (domain does not exist) responses from DNS servers.
 * This forces web browsers to a search page whenever a user attempts to browse to a domain that does not exist.

Dnsmasq can filter out these "bogus" NXDOMAIN records, preventing this potentially unwanted behavior.
