Comodo Secure DNS(科莫多提供) 8.26.56.26/8.20.247.20,对比114dns、dnspod、阿里DNS

2017-7-18 fredzeng dns

Comodo Secure DNS(科莫多提供) 8.26.56.26/8.20.247.20 查询速度非常快,一点也不输给dnspod的119.29.29.29 114DNS:114.114.114.114 阿里DNS:223.5.5.5

测试一下查询速度,Comodo Secure DNS(科莫多提供) 8.26.56.26/8.20.247.20基本在1毫秒到900毫秒,波动很大,但是定位不够准确,广东电信使用了

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。
