dnsmasq - 2.85-1+deb11u1 main

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.
