.com 根服务器直接部署在了广州墙内了吗? 好像都不过墙了，这延迟 GFW 要抢答都没机会了，多个省份似乎也走到广州

用 itdog 发现只有电信直连，移动连香港，联通连美国

[yaott2020]

先把你的 clash 关掉好吗

[yaott2020]

@yaott2020 抱歉，看错 ip 了

[leonshaw]

根服务器本来就是 anycast 的
https://root-servers.org/

[gentrydeng]

@leonshaw #5 这是 Verisign 的 gtld-servers.net ，不是 root-servers.net 。

[smallboy19991231]

有什麼影響嗎?

[gentrydeng]

虽然但是，你的结论是错误的。你不会以为现在的防火墙还只部署在“海关”出口吧，早就边缘化了。

[jiuhuicinv]

他再怎么快难道不走运营商线路？

用户 --> 电信运营商 --> 权威 dns

1 ，com,net 根在国内有 Anycast 节点，由 VeriSign 维护（ a-m.gtld-servers.net ）
2 ，中国有在境内建设 root 镜像根，上游是 13 个根服务器中的一个，镜像由中方维护（ a-m.root-servers.net ）

com,net 的境内节点完工日期甚至早于很多

[jiuhuicinv]

@jiuhuicinv 早于很多镜像根，但它们本质没有什么关联

[leonshaw]

@gentrydeng #1 说的是根，.com 也是类似的。话说回来运营商的 DNS 污染也不是靠墙做的。

[IDAEngine]

镜像节点

[lxcopenwrt]

没啥意义，你向谷歌的权威 DNS 请求 youtube.com 的 A/AAAA 记录的时候照样有抢答
