dnsmasq plugin
dnsmasq
: a lightweight DNS server. dnsmasq
accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server.
dnsmasq
can also provide DHCP and TFTP services to a small-scale network.
The dnsmasq plugin: instead of using the DNS nameserver assigned by DHCP, NetworkManager
will configure a local copy of dnsmasq
that can be customized.
