感觉是直接无视了所有AAAA类型的查询

百度我也查不到 AAAA，但是 v.qq.com 有。

上游说应该有

C:\Users\Admin>nslookup -qt=a+aaaa www.baidu.com. 119.29.29.29

          110.242.68.3

但是v.qq.com我这查也没有

C:\Users\Admin>nslookup -qt=a+aaaa v.qq.com.

所以是配置加载问题（相同配置原版smartdns正常）？编译问题？

应该不是编译问题，可能是测速模式。比如最快响应，就是谁响应快用谁，可能是错误的响应。

为避免混淆，采用单一上游

server-https https://120.53.53.53/dns-query -host-name doh.pub -group mainland -blacklist-ip

查询www.baidu.com仍没有ipv6结果。但是直接打开网页是有的 https://120.53.53.53/dns-query?name=www.baidu.com&type=28

{"Status":0,"TC":false,"RD":true,"RA":true,"AD":false,"CD":false,"Question":[{"name":"www.baidu.com.","type":28}],"Answer":[{"name":"www.baidu.com.","type":5,"TTL":1113,"data":"www.a.shifen.com."},{"name":"www.a.shifen.com.","type":28,"TTL":33,"data":"240e:e9:6002:15b:0:ff:b03c:259e"}]}

在改为单一上游后，试了v.qq.com也是没有ipv6结果

貌似可以重现了，我找时间看下。你能否提供最简重现配置？

注： baidu.com 仅在文件 mainland.txt 中

我又重现不了了，好像是上游确实没给

@mokeyish

用 server-https https://doh.sb/dns-query 拿不到 百度的 IPv6。
用 server-https https://120.53.53.53/dns-query 可以拿到。

当且仅当存在两个同名的domain-set且文件内容与目标域名无关时，该故障重现

@mokeyish

我又无法重现了，按你说的测了下都是正常的。我怀疑是不是原版的 最快响应模式是，最快的满足查询类型的响应，而不单单是最快而已。

@PikuZheng

单一上游不存在应答模式问题

#219 修复了。上游结果测速，再增加查询类型的检查，没有 IPv6 的结果会忽略，如果都没有只能 SOA 了。

同时上面的 UnKnown 服务器，应该也修复了。

@PikuZheng

未解决。。。感觉是配置加载问题
unknown是因为容器内，本地ip和请求ptr的ip不同

@mokeyish
Copy link
Owner

你说的 unknown 这种情况，貌似只能加配置选项，指定 IP 了，但貌似 C 版没有这选项。

没有 IPv6 的，你要先确保上游能够查的到。我是用这两个测试的

@PikuZheng

现在的版本更不对了，查询A+AAAA时，整个返回nxdomain了（以前的版本只有a记录）

配置

server-https https://dns.alidns.com/dns-query -group mainland

bind [::]:53
dualstack-ip-selection no

domain-set -name mainland -file /etc/smartdns/mainland.txt
#domain-set -name outbound -file /etc/smartdns/geoip.txt
domain-set -name outbound -file /etc/smartdns/google.txt
domain-set -name outbound -file /etc/smartdns/outbound.txt

domain-rules /domain-set:mainland/ -speed-check-mode ping -nameserver mainland
domain-rules /domain-set:outbound/ -speed-check-mode none -nameserver outbound -address #6

response-mode fastest-response

其中 baidu.com在文件 mainland.txt 中，baidu.jp 在文件 geoip.txt 中

查询

你这肯定不是 fastest-response ，fastest-response 是不测速的

不测速，返回两个 ipv6 地址：

方便的话，你可以调试看看的。vscode 也支持容器内部远程调试的。

没有windows环境。。纯容器编译运行

另外您这测试的配置还是不对，没有为上游服务器指定组
