当我做:
ping www.google.com
它返回了响应
PING www.google.com (172.253.122.147): 56 data bytes
所以这意味着www.google.com解析为 172.253.122.147。
我可以运行哪些命令来确定反向(即给定 172.253.122.147,它会吐出www.google.com)?

通常你会使用Nslookup - 名称服务器查找 - Windows CMD - SS64.com,但在这种情况下答案不是你想要的:
F:\test>nslookup 172.253.122.147
Server: UnKnown
Address: 192.168.249.155
Name: bh-in-f147.1e100.net
Address: 172.253.122.147
bh-in-f147.1e100.net
是名称服务器,没有与之关联的网站。它属于 Google:
Hostname Type TTL Priority Content
bh-in-f147.1e100.net SOA 60 ns1.google.com [email protected] 54750970 900 900 1800 60
bh-in-f147.1e100.net A 3600 172.253.122.147
bh-in-f147.1e100.net AAAA 3600 2607:f8b0:4004:c09::93
您也可以尝试whois
。在线版本位于WHOIS 搜索、域名、网站和 IP 工具 - Who.is它告诉你这个地址属于 Google:
