我正在使用MacOSX 10.14.1 Mojave ...
uname -a
Darwin *****.local 18.2.0 Darwin Kernel Version 18.2.0: Fri Oct 5 19:41:49 PDT 2018; root:xnu-4903.221.2~2/RELEASE_X86_64 x86_64
用于挖掘的手册页和多个在线线程均指示我正在发出正确的命令，但它未显示任何跟踪信息。它只是说已接收到12个字节，并且已解析ip地址。 / p>
答案 0 :(得分：0)
如果没有帮助，以下提示对我有帮助：
dig +trace some.domain.com并不总是在第一次尝试时显示跟踪，但是在几次尝试后它仍然有效！只需一次又一次输入相同的命令。答案 1 :(得分：-1)
这里没有Mac，但这可能与您的DNS服务器有关。您是否尝试过其他服务器，例如8.8.8.8？
使用127.0.0.53作为名称服务器时：
; <<>> DiG 9.11.3-1ubuntu1.3-Ubuntu <<>> +trace stackoverflow.com
;; global options: +cmd
;; Received 28 bytes from 127.0.0.53#53(127.0.0.53) in 0 ms
使用Google的名称服务器时：
dig @8.8.8.8 +trace stackoverflow.com
; <<>> DiG 9.11.3-1ubuntu1.3-Ubuntu <<>> @8.8.8.8 +trace stackoverflow.com
; (1 server found)
