     "Dnsmasq is a light-weight 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 on each host or in
a central configuration file.  Dnsmasq supports static and dynamic DHCP leases
and BOOTP/TFTP for network booting of diskless machines.")

number of programming techniques to improve speed.  For example, the responder
is completely lock-free, resulting in a very high response rate.  Other features
include automatic @dfn{DNS Security Extensions} (DNSSEC) signing, dynamic record
