摘要： In a computing device a domain name system (DNS) query is generated and sent, and a check is made as to whether a verified DNS response to the DNS query is received. The computing device is determined to be inside a particular network if a verified DNS response is received, and is determined to be outside that particular network if a verified DNS response is not received. A DNS response can be determined to be verified if both the DNS response has an expected value and the DNS response is digitally signed by a trusted authority, and otherwise can be determined to be not verified.
摘要翻译： 在计算设备中，生成并发送域名系统（DNS）查询，并且检查是否接收到对DNS查询的经过验证的DNS响应。 如果接收到已验证的DNS响应，则计算设备被确定在特定网络内，并且如果未接收到经验证的DNS响应，则确定该外部在该特定网络之外。 如果DNS响应具有预期值并且DNS响应由可信管理机构进行数字签名，则可以确定DNS响应以被验证，否则可以被确定为不被验证。

摘要： A network address of a computing device is obtained, and an unencrypted request is sent to a resource access manager of a particular network. If both a response is received from the resource access manager and the computing device has a network address within a desired range of network addresses, then a determination is made that the computing device is inside the particular network. Otherwise, a determination is made that the computing device is outside the particular network.
摘要翻译： 获得计算设备的网络地址，将未加密的请求发送到特定网络的资源访问管理器。 如果从资源访问管理器接收到响应并且计算设备具有期望的网络地址范围内的网络地址，则确定计算设备在特定网络内。 否则，确定计算设备在特定网络之外。
