convert IP to hostname
提问by Illusionist
I want to write a python script to convert IP addresses to hostnames. I am using a Linux box. I don't see this information in whois command. Are there any commands that always give the correct hostnames (as accurately as possible)?
我想编写一个 python 脚本来将 IP 地址转换为主机名。我正在使用 Linux 机器。我在 whois 命令中没有看到此信息。是否有任何命令总是提供正确的主机名（尽可能准确）？

The closest you're likely to get is socket.getfqdn(). It incorporates the results from gethostbyaddr(). Pass it an IP address as a string.
您可能得到的最接近的是socket.getfqdn()。它结合了 gethostbyaddr() 的结果。将 IP 地址作为字符串传递给它。

Socketlibrary has an API to do reverse DNS lookups.
import socket
socket.gethostbyaddr("8.8.8.8")
>>> ('google-public-dns-a.google.com', [], ['8.8.8.8'])
Keep in mind that not all IP addresses will have reverse DNS entries, not all aliases might be present in the answer to this query etc.
请记住，并非所有 IP 地址都具有反向 DNS 条目，并非所有别名都可能出现在此查询的答案中等。
