sudo dnsproxy -a "*.a.com:127.0.0.1" "*.b.a.com:127.0.0.2" "*:127.0.0.3" & dig @localhost xx.a.com # return 127.0.0.1 dig @localhost xx.b.a.com # return 127.0.0.2 dig @localhost any.other.domain # return 127.0.0.3
When "ip" configuration is "localhost", node-dnsproxy returns the requesting host IP address
当"ip"配置为"localhost"时,node-dnsproxy 返回请求主机的ip地址
When "ip" configuration is "proxyhost", node-dnsproxy returns the binding IP address of the server
当"ip"配置为"proxyhost"时,node-dnsproxy 返回服务器绑定的ip地址
# start server on 192.168.1.1 sudo dnsproxy -a who.am.i:localhost who.are.you:proxyhost & # run on 192.168.1.2 dig @192.168.1.1 who.am.i # return 192.168.1.2 dig @192.168.1.1 who.are.you # return 192.168.1.1 # run on 192.168.1.3 dig @192.168.1.1 who.am.i # return 192.168.1.3 dig @192.168.1.1 who.are.you # return 192.168.1.1
