dnsmasq: Small caching DNS proxy and DHCP/TFTP server

 Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP
 server. 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 for network booting of diskless machines.

dnsmasq-base: Small caching DNS proxy and DHCP/TFTP server

 This package contains the dnsmasq executable and documentation, but
 not the infrastructure required to run it as a system daemon. For
 that, install the dnsmasq package.

dnsmasq-base-lua: Small caching DNS proxy and DHCP/TFTP server

 This package contains the dnsmasq executable and documentation, but
 not the infrastructure required to run it as a system daemon. For
 that, install the dnsmasq package. This package is an alternative
 to dnsmasq-base which includes the LUA interpreter.

dnsmasq-utils: Utilities for manipulating DHCP leases

 Small utilities to query a DHCP server's lease database and
 remove leases from it. These programs are distributed with dnsmasq
 and may not work correctly with other DHCP servers.
