配置

默认配置，外部电脑是访问DNS 53 端口的，需要配置listen-address

查看本机IP地址：

ubuntu@10-9-124-19:~$ ip addr
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1454 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 52:54:00:c9:32:c3 brd ff:ff:ff:ff:ff:ff
    inet 10.9.124.19/16 brd 10.9.255.255 scope global eth0
       valid_lft forever preferred_lft forever

然后修改/etc/dnsmasq.conf

/etc/dnsmasq.conf

listen-address=127.0.0.1,10.9.124.19

重启服务

sudo systemctl restart dnsmasq

测试DNS解析

在网内另一台机器执行nslookup检查DNS解析是否可用

➜  ~ nslookup www.qq.com 10.9.124.19
Server:		10.9.124.19
Address:	10.9.124.19#53

Non-authoritative answer:
Name:	www.qq.com
Address: 180.163.26.39
