httpdns 能正常解析
curl 119.29.29.29/d?dn=fonts.gstatic.com
203.208.39.255;203.208.39.247;203.208.39.239;203.208.39.255;203.208.39.248;203.208.39.247;203.208.39.239;203.208.39.248
另外 119.28.28.28 182.254.116.116 182.254.118.118
也是相同的结果
1.2.4.8 就可以正常解析 所以应该不是 ISP 的劫持?

@iLiberty bind9.11 之后的版本默认开启了 cookie,DNSPod 的公共 DNS 和权威 DNS 都还没有支持 cookie,需要显示指定+nocookie 或使用 9.10 版本,之前已经转给相关开发同事了,会慢慢灰度,权威已经少量灰度。

@miaomiao888 @lhx2008 @laoyuan @lniwn 几个问题吧,1.今年 119.29.29.29 遇到的攻击特别多,就不说了,奇怪的是 114 竟然从最早到现在基本没遇到过攻击,个人可以先用 119.28.28.28 ,用户比较少,路由和 119.29.29.29 基本是一样的,节点完全一样。182.254.116.116,182.254.118.118 不推荐使用。 |

johnjiang85 2017-12-29 11:13:20 +08:00 1
再就是个别特殊域名在特定运营商可能有问题,这些大部分是递归到权威的线路和兼容性问题,后端节点太多,某些线路就可能被搞,或者权威对 ecs 的支持特别乱,自动判断是否支持 ecs 判断不出来,就得手工拉黑名单。都是需要人工验证操作的。具体就是需要提供域名、地区、运营商和截图了。

我这边测试了一下是 OK 的,119.29.29.29 能够正常解析到域名 fonts.gstatic.com 。不过查了这个域名是 google 的,有些网络不能解析可能跟运营商的限制有关,毕竟 google 退出中国之后,有些域名还是受到限制的。请看下面:

@iLiberty 河北联通到 119.28.28.28 的路由看上去确实有问题,先绕到四川又回了广东,应该是直接去天津的,我找网络的人问下。不过这个不应该影响解析结果的。在四川联通测试和携带河北联通的 ecs ip 都能解析到北京去,这个日本的 IP 不知道怎么出现
