[全球工单系统] 119.28.28.28 dig 空查询报错

这个 IP 是不是被放弃了。

好像 dnspod 的官网上已经查不到这个 IP 了。

直接 dig 查询会报错

dig @119.28.28.28
;; Truncated, retrying in TCP mode.
;; Connection to 119.28.28.28#53(119.28.28.28) for . failed: timed out.

119.29.29.29 是正常的

$ dig @119.29.29.29

但是跟着域名去解析又是正常的了

$ dig @119.28.28.28 www.baidu.com
