# DnsHosts

#### 介绍
一款用于修改app内主机域名映射的工具

#### 软件架构
通过Hook方式，实现应用内的DNS转向，非系统级别修改.  
支持IPv4/IPv6.  

#### 使用方式

```
  Map<String,String> dnsMap = new HashMap<>();
  dnsMap.put("www.baidu.com","127.0.0.1");
  dnsMap.put("www.taobao.com", "2001:0db8:3c4d:0015:0000:0000:1a2f:1a2b");
  DnsHostsManager.registerDns(dnsMap);
```
  
测试.  
```
    try {
            //被映射的域名
            InetAddress baidu = InetAddress.getByName("www.baidu.com");
            Log.d("DnsManager"," == " +baidu);
            InetAddress[] taobao = InetAddress.getAllByName("www.taobao.com");
            Log.d("DnsManager"," == " +taobao[0]);

            //未被映射的域名，走原有解析
            InetAddress tmall = InetAddress.getByName("www.tmall.com");
            Log.d("DnsManager"," == " +tmall);
            InetAddress qq = InetAddress.getByName("www.qq.com");
            Log.d("DnsManager"," == " +qq);
        } catch (Exception e) {
            e.printStackTrace();
        }
```
测试结果。 
```
D/DnsManager:  == www.baidu.com/127.0.0.1
D/DnsManager:  == www.taobao.com/2001:db8:3c4d:15::1a2f:1a2b
D/DnsManager:  == www.tmall.com/27.221.93.231
D/DnsManager:  == www.qq.com/220.194.120.49
