EDNS Client Subnet(ECS)是一种扩展DNS(EDNS)的选项,它允许DNS服务器了解查询的客户端的IP地址范围。这是通过递归DNS服务器在将查询转发给权威DNS服务器时,在DNS查询中包含客户端的IP地址信息来实现的。 阐述EDNS Client Subnet 在 DNS 查询中的作用 在DNS查询中,ECS的主要作用是帮助权威DNS服务器更准确地确定客户...
目前BIND不能支持EDNS需要打补丁后才能发送EDNS的查询包,请先下载edns-client-subnet dig patch并安装进BIND中。 1. 先将测试域名做多线路的域名解析 分别为edns.dns.com做了两条DNS智能解析,分别来自上海电信的用户解析到3.3.3.3,北京电信的用户解析到2.2.2.2,其它的都解析到1.1.1.1。 2. 使用打过edns-client-...
In the ZIA Admin Portal, you can configure a list of EDNS Client Subnet (ECS) prefixes and designate one of them to be embedded in DNS queries when they arrive at the ZIA Service Edges (Public, Private, or Virtual).A maximum of 128 ECS prefixes, including the default prefix, is support...

edns-client-subnet google提交了一份DNS扩展协议,允许DNS resolver传递用户的ip地址给authoritative DNS server. CDN的DNS支持该协议,就可以获取用户真实的IP地址,进行准确的调度。 OpenDNS和Google Public DNS已经支持了该协议,如果希望他们的query中带有用户IP,需要联系他们添加白名单。提供nameserver的hostname、ip以及...
Edns Client Subnet(ECS) ECS 是由Google提交的一份DNS扩展协议,主要作用是传递用户的IP地址给权威DNS服务器。 rfc7871(2016 年 5 月) 遵循ECS标准的公共DNS,会将经遮罩脱敏后的客户端ip添加至DNS扩展区域( EDNS rfc6891)传递至权威DNS (IPV4 遮罩通常为/24 IPV6 为 /56) 这样权威DNS服务器就可以获取到模糊...
3936. [func] Added authoritative support for the EDNS Client Subnet (ECS) option. ACLs can now include "ecs" elements which specify an address or network prefix; if an ECS option is included in a DNS query, then the address encoded ...
EDNS-Client-Subnet (ECS) is a draft informational RFC that uses the EDNS0 extensions to the DNS. Recursive DNS services that support ECS can provide the client (end-user) subnet as part of the DNS query, allowing authoritative DNS providers to use this extra information to make more informed...
