如何在Python中进行DNS查找，包括引用/ etc / hosts？ [英] How can I do DNS lookups in Python, including referring to /etc/hosts?

问题描述

dnspython 将非常好地进行DNS查找，但完全忽略的内容/ etc / hosts 。

dnspython will do my DNS lookups very nicely, but it entirely ignores the contents of /etc/hosts.

是否有一个python库调用将会做正确的事情？即先检查 etc / hosts ，否则退回到DNS查找？

Is there a python library call which will do the right thing? ie check first in etc/hosts, and only fall back to DNS lookups otherwise?

推荐答案

我不太确定你是否想自己进行DNS查找，或者你只想要一个主机的ip。如果你想要后者，

I'm not really sure if you want to do DNS lookups yourself or if you just want a host's ip. In case you want the latter,

import socket
print socket.gethostbyname('localhost') # result from hosts file
print socket.gethostbyname('google.com') # your os sends out a dns query
