‘播放’ 主机是什么?

我在 Ubuntu 机器上测试了以下内容。

命令

ping play

结果是

PING play (127.0.53.53) 56(84) bytes of data.
64 bytes from 127.0.53.53: icmp_seq=1 ttl=64 time=0.029 ms
64 bytes from 127.0.53.53: icmp_seq=2 ttl=64 time=0.036 ms
64 bytes from 127.0.53.53: icmp_seq=3 ttl=64 time=0.032 ms
64 bytes from 127.0.53.53: icmp_seq=4 ttl=64 time=0.030 ms

如果我执行以下操作:

ssh play

我可以登录到我自己的机器localhost

最后,以下内容:

dig play

结果是:
