Dnsmasq resolve domain name to intranet IP Address

Purpose: When a LAN User accesses a domain name, the user intercepts the access to the specified IP address and caches the IP address to save bandwidth.

Configuration:

1;> Yum install dnsmasq-y

2;> VI/etc/dnsmasq. conf

Resolve-file =/etc/dnsmasq. resolv. conf

Addn-hosts =/etc/dnsmasq. Hosts

Resolve-file specifies where dnsmasq obtains the upstream DNS server, which is obtained from/etc/resolv. conf by default.

Addn-hosts specifies the file from which dnsmasq reads the "address domain name" record. The default value is system file/etc/hosts;

By default, listen-address is monitored on all NICs.
