Overview

Dnsmasq is a DNS query forwarder. It will not answer arbitrary queries by recursively interact with root DNS servers. It will forward such queries to a fully recursive upstream DNS server.

The upstream servers can be inferred from /etc/resolv.conf (unless no-resolv is specified), specified on command line with --server option or specified in the Dnsmasq configuration files with:

server=192.168.122.12

The upstream servers specified on command line or in the configuration file can optionally take a domain name which tells dnsmasq to use that server only to find names in that particular domain.

Configuration

/etc/dnsmasq.conf

/etc/dnsmasq.d/

/etc/resolv.conf

Configuration Options

no-resolv

Do not read /etc/resolv.conf, get upstream servers only from command line or our own configuration files.

domain-needed

Never forward A or AAAA queries for plain names, without dots or domain parts, to upstream nameservers. If the name is not known from /etc/hosts or DHCP then a "not found" answer is returned.
