如何在Windows中以编程方式更改DNS服务器？

Question

我希望能够通过程序代码更改DNS服务器。我不想构建一个DNS服务器，只是想自动更改主要和次要的DNS服务器。这项工作需要用Python完成。

Answer 1

您可以使用os.system调用命令行工具来完成此操作。

import os
os.system('netsh interface ip set dns "Local Area Connection" static 192.168.0.200')

Answer 2

import os
# The first thing you need to import os and identify is the name of the network interface you want to modify.
# You can find the names of all network interfaces by running the following command:
os.system('netsh interface ipv4 show interfaces')
# for me its "Wi-Fi"
# For the primary DNS server run:
os.system('netsh interface ip set dns name="Wi-Fi" static 185.37.37.37')
# For the secondary DNS server run:
os.system('netsh interface ip add dns name="Wi-Fi"  185.37.39.39 index=2')
# whene you'r done with the DNS server run :
os.system('netsh interface ip set dnsservers name="Wi-Fi" source=dhcp')
#keep in mind  that you need administrator privilege
