    Google 的 8.8.8.8，CloudFlare 的 1.1.1.1，Quad9 的 9.9.9.9，OpenDNS 的 208.67.222.222...越来越多的企业和机构提供了免费的公共 DNS 解析服务，但它们的性能究竟谁更胜一筹，解析速度究竟有多快？

    有研究者利用了全球 18 个位置（不包括中国）测试了这些 DNS 服务的性能。除了 Yandex 的 77.88.8.7，所有 DNS 服务在北美和欧洲的响应速度都在 15ms 以内，也就是说如果你生活在这些地区，你可以选择任意的公共 DNS 服务。

    CloudFlare 的服务平均速度最快，全球平均响应速度仅仅为 4.98 ms，Google 和 Quad9 位居第二和第三，Quad9 在北美和欧洲比 Google 快，但在亚洲和南美比较慢；Yandex 只在俄罗斯比较快，其它地方都很慢。
