套接字使用特定的DNS服务器解析DNS [英] Socket resolve DNS with specific DNS server

问题描述

我想使用特定的DNS服务器来解析DNS，例如Google的8.8.8.8.我实际的Python代码是:

I want to resolve DNS with specific DNS server, for example Google's 8.8.8.8. My actual Python code is:

import socket

def getIP(d):
    try:
        data = socket.gethostbyname(d)
        ip = repr(data)
        return True
    except Exception:
        # fail gracefully!
        return False

是否可以使用Python?

Is it possible using Python?

推荐答案

您可以使用dnspython: http://www.dnspython.org/在ubuntu/debian上，您可以使用:

You can use dnspython: http://www.dnspython.org/ On ubuntu/debian you can get it using:

sudo apt-get install python-dnspython

否则，通过以下方式获取它:

Otherwise get it via:

sudo pip install dnspython

或下载源代码，通过以下方式安装它:

Or download the source install it via:

sudo python setup.py install

您的代码将如下所示:

from dns import resolver

res = resolver.Resolver()
res.nameservers = ['8.8.8.8']

answers = res.query('stackexchange.com')

for rdata in answers:
    print (rdata.address)

由于OP在Mac OS X上使用时似乎有问题，因此，我做了以下操作来安装它(仅适用于本地用户):

Since the OP seems to have issues using it on Mac OS X here is what I did to get it installed (for local user only):

git clone git://github.com/rthalley/dnspython.git
cd dnspython
python setup.py install --user
