Python中来自本地网络的IP地址/主机名列表 [英] List of IP addresses/hostnames from local network in Python

问题描述

如何使用Python轻松地从本地网络获取IP地址或主机名列表?

How can I get a list of the IP addresses or host names from a local network easily in Python?

最好是多平台的，但是它首先需要在Mac OS X上运行，然后才需要其他版本.

It would be best if it was multi-platform, but it needs to work on Mac OS X first, then others follow.

本地是指本地网络中的所有活动地址，例如192.168.xxx.xxx.

By local I mean all active addresses within a local network, such as 192.168.xxx.xxx.

因此，如果我的计算机(在本地网络中)的IP地址是192.168.1.1，并且我有另外三台已连接的计算机，则希望它返回IP地址192.168.1.2，192.168.1.3，，以及它们的主机名.

So, if the IP address of my computer (within the local network) is 192.168.1.1, and I have three other connected computers, I would want it to return the IP addresses 192.168.1.2, 192.168.1.3, 192.168.1.4, and possibly their hostnames.

推荐答案

如果本地"是指同一网段，则必须执行以下步骤:

If by "local" you mean on the same network segment, then you have to perform the following steps:

1. 确定您自己的IP地址
2. 确定自己​​的网络掩码
3. 确定网络范围
4. 扫描所有地址(最低的地址是您的网络地址，最高的地址是您的广播地址).
5. 使用DNS的反向查找来确定响应扫描的IP地址的主机名.

或者您也可以让Python在外部执行nmap并将结果通过管道传递回您的程序中.

Or you can just let Python execute nmap externally and pipe the results back into your program.
