显然，结果是0.0.xx.xx，xx是递增的。奇怪的！但是ping工作了。
$ ping baidu.com PING baidu.com (0.0.46.103): 56 data bytes 64 bytes from 123.125.114.144: icmp_seq=0 ttl=52 time=76.006 ms 64 bytes from 123.125.114.144: icmp_seq=1 ttl=52 time=3.757 ms ^C --- baidu.com ping statistics --- 2 packets transmitted, 2 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 3.757/39.882/76.006/36.124 ms
挖掘结果也很奇怪。

感谢任何帮助。
我做了什么？列表如下：
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist sudo killall -HUP mDNSResponder
从未工作过。
