小结：dnspod dns（腾讯DNS）119.29.29.29，查询定位很准确返回广东电信ip，查询速度稳定在10几毫秒，阿里dns、114dns都很快但是返回ip不是本省ip，可能是递归查询的ip节点不够多导致不准确。而Comodo Secure DNS（科莫多提供） 8.26.56.26/8.20.247.20 查询速度有时候最快，但是不稳定有时候几百毫秒，返回ip也不够精准同运营商不同省份，还是不稳定，不推荐。

114DNS还有拦截钓鱼病毒木马网站,拦截色情网站安全儿童模式DNS

1.纯净无劫持无需再忍受被强扭去看广告或粗俗网站之痛苦

服务地址为：114.114.114.114 和 114.114.115.115

2.拦截钓鱼病毒木马网站增强网银、证券、购物、游戏、隐私信息安全

拦截钓鱼病毒木马DNS服务地址为：114.114.114.119 和 114.114.115.119

3.学校或家长可选拦截色情网站保护少年儿童免受网络色情内容的毒害

拦截色情DNS服务地址为：114.114.114.110 和 114.114.115.110

如果有上述需求的，可以考虑下，效果还可以，延迟基本上在10ms以下，速度很好。

2017公共DNS服务质量评测报告

DNS在平时上网中扮演重要角色，如果不注意的话，可能会导致网速慢、弹窗广告、网址打不开、打开不是自己想要的网站、劫持、墙中墙等一系列问题。针对DNS的问题，今天我们就来总结一下，看看哪个DNS服务器最好用！

CNNIC SDNS：★★★

SDNS是由中国互联网络信息中心(CNNIC)推出的免费解析服务(SecureDNS,简称SDNS)。

DNS 服务器 IP 地址：

首选：1.2.4.8

备选：210.2.4.8

作者点评：作为国家出品的DNS，有待测试……（你敢用吗？反正我不敢）查询速度38毫秒，返回内容太多了，注定也慢。

OpenDNS：★★

OpenDNS创建于2006年，长期以来致力于为广大个人用户以及商务企业用户和公共领域提供免费的域名解析服务。

DNS 服务器 IP 地址：

首选：208.67.222.222

备选：208.67.220.220

作者点评：国内节点少，延迟高，解析结果受GFW的影响不一定准确，66毫秒，跟国内比查了几倍速度了。

最后总结

测试结果受用户地区和DNS提供商的服务器等不同因素影响。建议用户在选择DNS时可以依照本排行，ping不同dns服务商的首选DNS地址，一般是哪个延迟最低用哪个。不同地区我也不好发言。建议不要使用运营商默认的DNS！推荐DNSPodDNS:119.29.29.29/182.254.116.116，114DNS:114.114.114.114/114.114.114.115，阿里DNS：223.5.5.5/223.6.6.6

114DNS、Dnspod DNS、阿里DNS、百度DNS、360DNS、Google DNS公共DNS评测体验报告

114DNS、腾讯dnspod DNS、阿里DNS、百度DNS、360DNS、Google DNS公共DNS评测体验报告从ping及dig返回时间对比测试，国内DNS普遍很快，而阿里DNS最快，次之腾讯dnspod DNS，然后114DNS，百度及360DNS中规中矩，而Google DNS还是很慢，我们还是拥抱国产DNS吧，推荐腾讯DNSPOD DNS 119.29.29.29 阿里DNS 223.6.6.6、223.5.5.5

114DNS、Google DNS、阿里DNS、OpenDNS等公共DNS评测体验报告

114DNS、Google DNS、阿里DNS、OpenDNS等公共DNS评测体验报告，主要从17ce来测试这些公共DNS的网络质量延时及丢包情况。测试总结国内推荐使用114DNS及阿里DNS，国外推荐Google DNS及OpenDNS。

1、之前用114DNS，是因为他网官上的介绍：

纯净无劫持无需再忍受被强扭去看广告或粗俗网站之痛苦

服务地址为：114.114.114.114 和 114.114.115.115

拦截钓鱼病毒木马网站增强网银、证券、购物、游戏、隐私信息安全

服务地址为：114.114.114.119 和 114.114.115.119

学校或家长可选拦截色情网站保护少年儿童免受网络色情内容的毒害

服务地址为：114.114.114.110 和 114.114.115.110

如果有上述需求的，可以考虑下，速度不错，使用BGP技术，3大运营商延迟基本上在10ms以下，速度很好。

公共DNS（114DNS、Google DNS、阿里DNS、OpenDNS等公共DNS）评测体验报告，国内推荐使用114DNS及阿里DNS，国外推荐Google DNS及OpenDNS。 - 文明 - LINUX|WEB|DB|DNS|CDN

2、阿里DNS： 223.5.5.5 223.6.6.6

与114DNS一样使用BGP技术，3大运营商延迟在25ms左右，基本不掉包，速度可以保证，如果不恶心阿的同学是可以考虑的，毕竟是国内的，访问速度可以保证的。

3、Google DNS： 8.8.8.8 8.8.4.4

几乎从知道这个DNS之后就一直在用，延迟在50ms左右，速度还可以，就是由于众所周知的原因，掉包比较严重，我在使用的时候也会有相应的感觉，但我是可以接受的。

4、V2EX DNS：199.91.73.222 178.79.131.110

延迟有点高，两个都在250ms以上，偶尔掉包，不建议。详细延时测试参考：

5、OpenDNS：208.67.222.222 208.67.220.220

知道这个比Google还早，也是非常知名的，但延迟有点高，在180ms左右，偶尔掉包，除了延迟大点，没有什么不能接受的。

6、其他的运营商默认的DNS，反正我是不用，偶弹广告。

最后，说一下最好的选择吧，如果是国内用户，没有洁癖的，可以考虑114DNS和阿里NDS，如果有洁癖，国外的可以选择很多优先Google的，虽然延迟，但我能够接受，其他的看自己的网络情况了。
