Summary(ru_RU.UTF-8): Компактный сервер DNS и DHCP для локальных сетей

%description
Dnsmasq is 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 for network booting of diskless machines.

%description -l ru_RU.UTF-8
Dnsmasq - это компактный, простой в настройке сервер DNS и DHCP,
разработанный для использования в небольших сетях.
По умолчанию он использует общесистемные файлы /etc/hosts и /etc/resolv.conf,
поэтому может использоваться без настройки сразу после установки.

Очень удобными функциями являются прозрачное переопределение внешних имён
через /etc/hosts и трансляция имени в наиболее подходящий клиенту IP-адрес,
если для имени определено несколько адресов из разных подсетей.
