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.
