 ![SmartDNS](doc/smartdns-banner.png)
 SmartDNS 是一个运行在本地的 DNS 服务器，它接受来自本地客户端的 DNS 查询请求，然后从多个上游 DNS 服务器获取 DNS 查询结果，并将访问速度最快的结果返回给客户端，以此提高网络访问速度。
-SmartDNS 同时支持指定特定域名 IP 地址，并高性匹配，可达到过滤广告的效果。  
+SmartDNS 同时支持指定特定域名 IP 地址，并高性匹配，可达到过滤广告的效果; 支持DOT(DNS over TLS)和DOH(DNS over HTTPS)，更好的保护隐私。
 与 DNSmasq 的 all-servers 不同，SmartDNS 返回的是访问速度最快的解析结果。详细差异请看[常见问题](#常见问题)。

 支持树莓派、OpenWrt、华硕路由器原生固件和 Windows 系统等。

 3. 启用服务
-   
-   SmartDNS 服务生效方法有两种，一种是**直接作为主 DNS 服务**，另一种是**作为 DNSmasq 的上游**。
-   默认情况下，SmartDNS 采用第一种方式。如下两种方式根据需求选择即可。
-   
-   - **方法一：作为主 DNS 服务（默认方案）**
     
-     * 启用 SmartDNS 的 53 端口重定向
-       
-       登录 OpenWrt 管理界面，点击 `Services` -> `SmartDNS` -> `redirect`，选择 `重定向 53 端口到 SmartDNS `启用 53 端口转发。
-     
-     * 检测转发服务是否配置成功
-       
-       执行
-       
-       ```shell
-       $ nslookup -querytype=ptr smartdns
+  * 替换默认Dndmasq为主DNS。
+    
+    登录 OpenWrt 管理界面，点击 `Services` -> `SmartDNS` -> `port`，设置端口号为`53`，smartdns会自动接管主DNS服务器。
+
+  * 检测转发服务是否配置成功
+    
+    执行
+    
+    ```shell
+    $ nslookup -querytype=ptr smartdns
+    ```
+    
+    查看命令结果中的 `name` 是否为 `smartdns` 或你的主机名，如果是则表示生效

-     
-     * 界面提示重定向失败
-       
-       * 检查 `iptables` 和/或 `ip6tables` 命令是否正确安装。
-       
-       * OpenWrt 15.01 系统不支持 IPv6 重定向，如网络需要支持 IPv6，请将 DNSmasq 上游改为 SmartDNS，或者将 SmartDNS 的端口改为53，并停用 DNSmasq。
-       
-       * LEDE 系统请安装 IPv6 的 NAT 转发驱动。点击 `System` -> `Software`，点击 `Update lists` 更新软件列表后，安装 `ip6tables-mod-nat`。
-       
-       * 使用如下命令检查路由规则是否生效
-         
-         ```shell
-         iptables -t nat -L PREROUTING | grep REDIRECT
-         ```

-   - **方法二：作为 DNSmasq 的上游**
-

    Since iOS14, Apple has supported the resolution of DNS HTTPS (TYPE65) records. This function is used for solving problems related to HTTPS connections, but it is still a draft, and it will cause some functions such as adblocking fail. It is recommended to disable it through the following configuration.

+1. How to resolve localhost ip by hostname?  
    smartdns can cooperate with the dhcp server of DNSMASQ to support the resolution of local host name to IP address. You can configure smartdns to read the lease file of dnsmasq and support the resolution. The specific configuration parameters are as follows, (note that the DNSMASQ lease file may be different for each system and needs to be configured according to the actual situation)

    ```sh
    dnsmasq-lease-file /var/lib/misc/dnsmasq.leases
-    ````\
+    ```

    After the configuration is complete, you can directly use the host name to connect to the local machine. But need to pay attention:

    * Windows system uses mDNS to resolve addresses by default. If you need to use smartdns to resolve addresses under Windows, you need to add `.` after the host name, indicating that DNS resolution is used. Such as `ping smartdns.`

+1. How to use the domain set?  
+    To facilitate configuring domain names by set, for configurations with /domain/, you can specify a domain name set for easy maintenance. The specific method is:
+    
+    * Use `domain-set` configuration domain set file:
+    
+    ````sh
+    domain-set -name ad -file /etc/smartdns/ad-list.conf
+    ````
+
+    The format of ad-list.conf is one domain per line:
+    
+    ````
+    ad.com
+    site.com
+    ````
+
+    * To use the domain set, you only need to configure `/domain/` to `/domain-set:[collection name]/`, such as:
+
+    ````sh
+    address /domain-set:ad/#
+    domain-rules /domain-set:ad/ -a #
