<p>You should use <a href="http://pypi.python.org/pypi/netifaces/" rel="noreferrer">netifaces</a>. It is designed to be cross-platform and contains specialised code for Windows together with a variety of generic versions that work on different UNIX/UNIX-like platforms.</p>

<p>As of <a href="http://pypi.python.org/pypi/netifaces/" rel="noreferrer">netifaces</a> version 0.10.0, Python3 is supported.</p>

<h2>Usage Summary</h2>

<pre><code>&gt;&gt;&gt; from netifaces import AF_INET, AF_INET6, AF_LINK, AF_PACKET, AF_BRIDGE
&gt;&gt;&gt; import netifaces as ni
&gt;&gt;&gt; ni.interfaces()
['lo', 'eth0', 'eth1', 'vboxnet0', 'dummy1']

<h3>Windows Support:</h3>

<p>No compiler required for most MS Windows installs.  If you get warnings about installing MS Visual C++ for Windows, be <a href="https://stackoverflow.com/questions/2817869/error-unable-to-find-vcvarsall-bat#comment23311731_10558328">very careful</a> because you need to match the version of compiler used for your python with that used for the module.</p>

Obtain information about the specified network interface.

Returns a dict whose keys are equal to the address family constants,
e.g. netifaces.AF_INET, and whose values are a list of addresses in
that family that are attached to the network interface.

<p>The numbers used to index protocols are from <code>/usr/include/linux/socket.h</code> (in Linux)...  <em>EDIT</em>: my 3.2 kernel has them here: <code>/usr/src/linux-headers-3.2.0-4-common/include/linux/socket.h</code></p>

<p>The good news is that you don't have to remember all those header constants, they are included with <a href="http://pypi.python.org/pypi/netifaces/" rel="noreferrer">netifaces</a>:</p>

<p>I use this solution. It's a little bit tricky actually, and it's only works on linux family.</p>

<pre><code>import commands
intf = 'eth0'
intf_ip = commands.getoutput("ip address show dev " + intf).split()
intf_ip = intf_ip[intf_ip.index('inet') + 1].split('/')[0]
print intf_ip
</code></pre>

<p>Those code utilize <code>ip</code> command on linux family operating system. It split the output from <code>ip</code> command and only take the IPv4 address of those interface. You can change the value <code>intf</code> to <code>eth1</code> or <code>p2p1</code>.</p>

<p>What I have done so far, using PyQt classes:</p>

<pre><code>all_Addresses = QNetworkInterface.allAddresses()    #list-of-QHostAddress

for addr in all_Addresses:
    print(addr.toString())
</code></pre>

<p>Output:</p>

<pre><code>172.16.0.186 - Virtual Interface IP address
192.168.10.2 - Physical interface IP address. I want this one.
127.0.0.1
</code></pre>

<p>Using <code>socket</code>:</p>

<pre><code>import socket
print(socket.gethostbyname(socket.gethostname()))
</code></pre>

<p>Output:</p>

<pre><code>172.16.0.186 - When openVPN is on
192.168.10.2 - When its off
</code></pre>

<ol>
<li>Is there a way to distinguish between them?</li>
<li>Can this be done with ordinary Python, instead of using PyQt classes?</li>
<li>How can I get the IPv6 address as well?</li>
</ol>


How to get the physical interface IP address from an interface

Windows

Python

Linux

到目前为止，我使用PyQt类完成了以下工作：all_Addresses = QNetworkInterface.allAddresses()    #list-of-QHostAddressfor addr in all_Addresses:    print(addr.toString())输出：172.16.0.1...
