这个 DNS 问题好奇怪， ping， nslookup 都不好使了，但是网站访问正常。

每次解析到的IP都是+1，都是内网地址。
比如这次解析到的IP是：127.128.0.2
下次随便一个域名解析到的IP就是：127.128.0.3
我用的阿里DNS呀，换百度的DNS结果也是一样的。
奇怪的是浏览器访问各个网站都是很正常的。命令行下用TCP模式也能正常。

P99LrYZVkZkg OP @Septembers 我用了DnsCrypt，unbound，都一样。
关键最奇怪的是我刚查把网全部断了，重启。 > nslookup ccc.com Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: Name: ccc.com Address: 127.128.0.13 > nslookup ddd.com Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: Name: ddd.com Address: 127.128.0.14 |

问题出在ProxyCap的Resolve names remotely选项上

P99LrYZVkZkg OP @loveyu 是的，上次差点重装系统，最后在Twitter上查到ProxyCap的问题。
