使用响应政策添加自定义规则,以修改网络中处理 DNS 查询的方式。DNS 解析器会在 DNS 查询期间参照这些规则。借助响应政策,您可以使用规则(而非记录)自定义专用区域内的 DNS 管理。如果响应政策中的规则影响传入的查询,则处理该规则;否则,查找将正常运行。使用这些规则可实现与 DNS 响应政策区 (RPZ) 草稿概念 (IETF) 类似的结果。如需了解如何管理响应政策,请参阅管理响应政策和规则。
响应政策与 RPZ 不同,RPAZ 是普通的 DNS 地区,具有特殊的格式数据,可导致兼容的解析器对查询提供不同的响应。响应政策不是 DNS 区域,可单独管理。如需了解详情,请参阅管理响应政策和规则。
路由政策
针对资源记录集使用 DNS 路由政策,以根据查询和其他因素(例如加权轮循 [WRR]、地理定位或故障切换)引导流量。借助 DNS 路由政策,您可以执行以下操作:
[[["易于理解","easyToUnderstand","thumb-up"],["解决了我的问题","solvedMyProblem","thumb-up"],["其他","otherUp","thumb-up"]],[["很难理解","hardToUnderstand","thumb-down"],["信息或示例代码不正确","incorrectInformationOrSampleCode","thumb-down"],["没有我需要的信息/示例","missingTheInformationSamplesINeed","thumb-down"],["翻译问题","translationIssue","thumb-down"],["其他","otherDown","thumb-down"]],["最后更新时间 (UTC):2025-04-03。"],[[["Cloud DNS offers server policies for configuring private DNS in a Virtual Private Cloud (VPC), including DNS forwarding and logging."],["Response policies allow for the customization of DNS query handling within a network by overriding private DNS responses based on the query name."],["Routing policies direct traffic based on various factors, such as round robin and geolocation, to steer traffic to specific locations or services."],["All three types of policies (server, response, and routing) can be implemented simultaneously to fit the specific needs of your network setup."]]],[]]
