请参阅图1B，图1B是本申请实施例提供的一种电子设备开启Wi-Fi热点时网络数据在电子设备内部进行传输的流程示意图，如图1B所示，网络数据的数据包从应用层发包时，数据包从应用层到达linux内核kernel网络协议栈，再经由路由层和硬件发送到网络，应用层收包时，通过硬件收包，发送至驱动，再由驱动发送至kernel网络协议栈，最后从kernel网络协议栈发送至应用层。
请参阅图1C，图1C是本申请实施例提供了一种DNS查询方法的流程示意图，应用于如图1A所示的电子设备，如图1C所示，本DNS查询方法包括：
101、开启Wi-Fi热点，并将目标IP地址分配给待接入所述Wi-Fi热点的终端设备，其中，所述目标IP地址为目标DNS服务器的IP地址，所述目标DNS服务器为给所述电子设备提供数据网络的DNS服务器。
本申请实施例中，电子设备可启用Wi-Fi热点来共享网络数据给其他的终端设备，其他终端设备可通过连接该Wi-Fi热点实现上网，在开启Wi-Fi热点时，会启用一个软件无线接口(soft access point，soft ap)，该soft ap接口对应第一IP地址，假定该第一IP地址为192.168.43.1，电子设备通过soft ap接口可用于接收终端设备的DNS请求，电子设备在在开启Wi-Fi热点时，可通过启用一个dnsmasq服务进程，将目标IP地址分配给待接入所述Wi-Fi热点的终端设备，目标IP地址为目标DNS服务器的IP地址，目标IP地址例如可以为10.10.10.2，目标DNS服务器为给电子设备提供数据网络的DNS服务器，从而，终端设备可通过连接soft ap接口，并通过soft ap接口获取目标DNS服务器对应的目标IP地址。
102、接收所述终端设备发送的DNS请求，所述DNS请求携带网络请求数据。
本申请实施例中，电子设备可通过soft ap接口接收终端设备发送的DNS请求，该DNS请求携带网络请求数据，DNS请求中还包含网络请求数据发送的目标位置。

本申请实施例中，当终端设备发送DNS请求，是向电子设备发送目的IP地址为目标IP地址的DNS请求，当DNS请求携带的网络请求数据发送至电子设备的kernel网络协议栈，可通过kernel网络协议栈的PREROUTING处理点进行路由查找，得到目标路由，然后由目标路由确定网络请求数据是要发送至目标DNS服务器。
103、将所述网络请求数据发送至所述目标DNS服务器。
其中，将网络请求数据发送至目标DNS服务器，可通过kernel网络协议栈的FARWARD处理点转发，并通过驱动层发送至目标DNS服务器。
可选地，上述步骤103中，将所述网络请求数据发送至所述目标DNS服务器，可包括以下步骤：
31、将所述网络请求数据通过所述kernel网络协议栈的FARWARD处理点转发至所述kernel网络协议栈的POSTROUTING处理点；

其中，当目标路由确定网络请求数据是要发送至目标DNS服务器，可通过FARWARD处理点转发至kernel网络协议栈的POSTROUTING处理点，然后通过电子设备的驱动层将网络请求数据发送至目标DNS服务器。
一般来说，若电子设备分配给移动终端的IP地址为第一IP地址，目标路由根据第一IP地址确定通过kernel网络协议栈的INPUT处理点发送至应用层，然后通过应用层将网络请求数据发送至kernel网络协议栈的OUTPUT处理点，再发送至kernel网络协议栈的POSTROUTING处理点，提供网络数据的目标DNS服务器，最后从驱动层发送至目标DNS服务器，其中，将网络请求数据从kernel网络协议栈的INPUT处理点发送至应用层，再从应用层发送至kernel网络协议栈的OUTPUT处理点，需要消耗较长时间，可见，本申请发送网络请求数据的方式，无需将网络请求数据从kernel网络协议栈的INPUT处理点发送至应用层，再从应用层发送至kernel网络协议栈的OUTPUT处理点，从而，可减少DNS查询的时间，提升DNS查询的效率。
104、接收所述目标DNS服务器发送的网络响应数据，将所述网络响应数据发送至所述终端设备。
本申请实施例中，当目标DNS服务器解析到DNS请求的结果，可向电子设备发送网络响应数据，由电子设备将网络响应数据转发至终端设备，从而实现终端设备的上网功能。

41、将所述网络响应数据通过所述kernel网络协议栈的FARWARD处理点转发至所述kernel网络协议栈的所述POSTROUTING处理点；
42、通过所述驱动层将所述网络响应数据发送至所述终端设备。
其中，当目标路由确定网络响应数据是要发送至目标DNS服务器，可通过FARWARD处理点转发至kernel网络协议栈的POSTROUTING处理点，然后通过电子设备的驱动层将网络响应数据发送至终端设备，本申请发送网络响应数据的方式，无需将网络响应数据从kernel网络协议栈的INPUT处理点发送至应用层，再从应用层发送至kernel网络协议栈的OUTPUT处理点，从而，可减少DNS查询的时间，提升DNS查询的效率。
举例说明，请参阅图1D，图1D为本申请实施例提供的一种电子设备终端设备的接收DNS请求并发送给目标DNS服务器的流程示意图，在电子设备开启Wi-Fi热点时，可启用一个soft ap接口，soft ap接口的第一IP地址为192.168.43.1，电子设备通过soft ap接口将目标IP地址10.10.10.2分配给待接入的终端设备，终端设备可通过第一IP地址192.168.43.1向电子设备的soft ap接口发送DNS请求，DNS请求中携带目的IP地址以及网络请求数据，该目的IP地址为目标IP地址10.10.10.2，当网络请求数据发送至kernel网络协议栈，可通过PREROUTING处理点进行路由查找，得到目标路由，通过目标路由确定DNS请求的目的IP地址为目标IP地址10.10.10.2，并将网络请求数据通过FARWARD处理点转发至 kernel网络协议栈的POSTROUTING处理点，最后，通过电子设备的驱动层将网络请求数据根据目标IP地址发送至目标DNS服务器。
进一步地，当目标DNS服务器解析到DNS请求的结果，可向电子设备发送网络响应数据，当电子设备的kernel网络协议栈接收到网络响应数据，通过PREROUTING处理点进行路由查找，得到目标路由，目标路由确定网络响应数据的发送位置为终端设备，并将网络响应数据通过FARWARD处理点转发至kernel网络协议栈的POSTROUTING处理点，最后，通过驱动层将网络响应数据发送至终端设备，从而实现终端设备的上网功能。
可以看出，本申请实施例中，电子设备首先开启Wi-Fi热点，并将目标IP地址分配给待接入Wi-Fi热点的终端设备，其中，目标IP地址为目标DNS服务器的IP地址，目标DNS服务器为给电子设备提供数据网络的DNS服务器，接收终端设备发送的DNS请求，DNS请求携带网络请求数据，将网络请求数据发送至目标DNS服务器，接收目标DNS服务器发送的网络响应数据，将网络响应数据发送至终端设备，如此，可在通过电子设备的Wi-Fi热点上网时，通过提供数据网络的DNS服务器的IP地址进行DNS查询，减少查询时间，提升查询效率。

在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
在本申请所提供的几个实施例中，应该理解到，所揭露的装置，可通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件程序模块的形式实现。
所述集成的单元如果以软件程序模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储器中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储器中，包括若干指令用以使得一台计算机设备(可为个人计算机、服务器或者网络设备等)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储器包括：U盘、只读存储器(read-only memory，ROM)、随机存取存储器(random access memory，RAM)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成，该程序可以存储于一计算机可读存储器中，存储器可以包括：闪存盘、ROM、RAM、磁盘或光盘等。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
