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. ^[3]^[4]

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.
