功能1：可否支持通配符、正则表达式，类似自定义协议匹配，简化批量解析的人工操作成本。

功能2：域名匹配 “作用范围”，引入 终端分组、IP段、IP地址，默认为 * ，对所有请求生效。

问题反馈：
经反复实验，强制客户端DNS代理，无缓存加速效果，希望能改善。
实验步骤：
1、开启“强制客户端DNS代理”
2、使用dnsperf压测dns
3、压测，5000个请求有21个请求超时
  1. [root@youku ~]# dnsperf  -c 5000 -d test -s 223.5.5.5
  2. DNS Performance Testing Tool
  3. Version 2.3.2

  5. [Status] Command line: dnsperf -c 5000 -d test -s 223.5.5.5
  6. [Status] Sending queries (to 223.5.5.5)
  7. [Status] Started at: Sun Jun 28 17:42:15 2020
  8. [Status] Stopping after 1 run through file
  9. [Timeout] Query timed out: msg id 78
  10. [Timeout] Query timed out: msg id 81
  11. [Timeout] Query timed out: msg id 82
  12. [Timeout] Query timed out: msg id 87
  13. [Timeout] Query timed out: msg id 88
  14. [Timeout] Query timed out: msg id 89
  15. [Timeout] Query timed out: msg id 90
  16. [Timeout] Query timed out: msg id 91
  17. [Timeout] Query timed out: msg id 92
  18. [Timeout] Query timed out: msg id 93
  19. [Timeout] Query timed out: msg id 94
  20. [Timeout] Query timed out: msg id 96
  21. [Timeout] Query timed out: msg id 97
  22. [Timeout] Query timed out: msg id 98
  23. [Timeout] Query timed out: msg id 99
  24. [Timeout] Query timed out: msg id 101
  25. [Timeout] Query timed out: msg id 102
  26. [Timeout] Query timed out: msg id 103
  27. [Timeout] Query timed out: msg id 105
  28. [Timeout] Query timed out: msg id 120
  29. [Timeout] Query timed out: msg id 797
  30. [Status] Testing complete (end of file)

  32. Statistics:

  34.   Queries sent:         5001
  35.   Queries completed:    4980 (99.58%)
  36.   Queries lost:         21 (0.42%)

  38.   Response codes:       NOERROR 4980 (100.00%)
  39.   Average packet size:  request 31, response 92
  40.   Run time (s):         0.937886
  41.   Queries per second:   5309.813773

  43.   Average Latency (s):  0.014464 (min 0.000967, max 0.028187)
  44.   Latency StdDev (s):   0.002105
复制代码
4、DNS加速模式改为“缓存模式”
5、再次压测，从结果可以看出所有请求完成，无超时现象，响应速度比强制代理更快。
  1. [root@youku ~]# dnsperf  -c 5000 -d test -s 223.5.5.5
  2. DNS Performance Testing Tool
  3. Version 2.3.2

  5. [Status] Command line: dnsperf -c 5000 -d test -s 223.5.5.5
  6. [Status] Sending queries (to 223.5.5.5)
  7. [Status] Started at: Sun Jun 28 17:44:41 2020
  8. [Status] Stopping after 1 run through file
  9. [Status] Testing complete (end of file)

  11. Statistics:

  13.   Queries sent:         5001
  14.   Queries completed:    5001 (100.00%)
  15.   Queries lost:         0 (0.00%)

  17.   Response codes:       NOERROR 5001 (100.00%)
  18.   Average packet size:  request 31, response 90
  19.   Run time (s):         0.204626
  20.   Queries per second:   24439.709519

  22.   Average Latency (s):  0.003664 (min 0.000571, max 0.011456)
  23.   Latency StdDev (s):   0.000877
