设备无法ping通www.google.com，但可以ping 8.8.8.8。 我的操作系统是Android 6.0.1，内核是4.1.15
我已经尝试过resolv.conf和/ etc / hosts。但是这些方法似乎无法在Android上使用。
我不知道确切的问题是什么。

我关闭了netd服务，以便能够分别配置eth0和eth1。
这是我的IP规则
0: from all lookup local
9998: from all to 192.168.120.0/23 lookup 4
9999: from all to 192.168.1.0/24 lookup 3
10000: from all fwmark 0xc0000/0xd0000 lookup legacy_system
13000: from all fwmark 0x10063/0x1ffff lookup local_network
15000: from all fwmark 0x0/0x10000 lookup legacy_system
16000: from all fwmark 0x0/0x10000 lookup legacy_network
17000: from all fwmark 0x0/0x10000 lookup local_network
23000: from all fwmark 0x0/0xffff uidrange 0-0 lookup main
32000: from all unreachable
这是ping IP的结果，您可以看到响应很好。

但是ping google总是返回未知数。
ping: unknown host www.google.com
我希望我可以查验IP和URL。
顺便说一句，来自eth0 192.168.1.245的DNS和来自eth1的DNS是8.8.8.8
