ChinaDNS 的上游 DNS 分为 国内 DNS 和 可信 DNS。
- ChinaDNS 会同时向上游的 DNS 发送请求。
- 如果
可信 DNS先返回，则直接采用可信 DNS的结果。 - 如果
国内 DNS先返回，分两种情况：如果返回的结果是国内的 IP, 则采用；否则丢弃并转而采用可信 DNS的结果。

[Plot histograms with pre-computed counters] Plot histograms with Marplotlib hist function or Seaborn distplot function using pre-counted values using 'weights' argument. Very useful for plotting distributions of values queried from a very large dataset, where it is impossible to retrieve and load in memory every element of the distribution inde…
