import socket
[i[4][0] for i in socket.getaddrinfo(socket.gethostname(), None)]

import socket
socket.gethostbyname(socket.gethostname())

这并不总是有效(在/etc/hosts主机名为127.0.0.1的机器上返回127.0.0.1)，gimel显示的是一个缓和的方法，使用socket.getfqdn()代替。当然，您的机器需要一个可解析的主机名。

恐怕除了连接到另一台计算机并让它把你的IP地址发送给你之外，没有任何好的独立于平台的方法来做到这一点。例如:findmyipaddress。注意，如果你需要一个NAT后的IP地址，除非你所连接的计算机也是NAT后的IP地址，这是行不通的。

下面是一个适用于Linux的解决方案:获取与网络接口关联的IP地址。

稍微改进了使用IP命令的命令版本，并返回IPv4和IPv6地址:

import commands,re,socket

#A generator that returns stripped lines of output from "ip address show"
iplines=(line.strip() for line in commands.getoutput("ip address show").split('\n'))

#Turn that into a list of IPv4 and IPv6 address/mask strings
addresses1=reduce(lambda a,v:a+v,(re.findall(r"inet ([\d.]+/\d+)",line)+re.findall(r"inet6 ([\:\da-f]+/\d+)",line) for line in iplines))
#addresses1 now looks like ['127.0.0.1/8', '::1/128', '10.160.114.60/23', 'fe80::1031:3fff:fe00:6dce/64']

#Get a list of IPv4 addresses as (IPstring,subnetsize) tuples
ipv4s=[(ip,int(subnet)) for ip,subnet in (addr.split('/') for addr in addresses1 if '.' in addr)]
#ipv4s now looks like [('127.0.0.1', 8), ('10.160.114.60', 23)]

#Get IPv6 addresses
ipv6s=[(ip,int(subnet)) for ip,subnet in (addr.split('/') for addr in addresses1 if ':' in addr)]

这个答案是我个人试图解决获得LAN IP的问题，因为socket.gethostbyname(socket.gethostname())也返回127.0.0.1。这种方法不需要Internet，只需要一个局域网连接。代码是为Python 3编写的。X但是可以很容易地转换为2.x。使用UDP广播:

import select
import socket
import threading
from queue import Queue, Empty

def get_local_ip():
        def udp_listening_server():
            s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
            s.bind(('<broadcast>', 8888))
            s.setblocking(0)
            while True:
                result = select.select([s],[],[])
                msg, address = result[0][0].recvfrom(1024)
                msg = str(msg, 'UTF-8')
                if msg == 'What is my LAN IP address?':
                    break
            queue.put(address)

        queue = Queue()
        thread = threading.Thread(target=udp_listening_server)
        thread.queue = queue
        thread.start()
        s2 = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        s2.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
        waiting = True
        while waiting:
            s2.sendto(bytes('What is my LAN IP address?', 'UTF-8'), ('<broadcast>', 8888))
            try:
                address = queue.get(False)
            except Empty:
                pass
            else:
                waiting = False
        return address[0]

if __name__ == '__main__':
    print(get_local_ip())

127.0.1.1是您的真实IP地址。更一般地说，一台计算机可以有任意数量的IP地址。您可以过滤它们为私有网络- 127.0.0.0/8,10.0.0.0/8,172.16.0.0/12和192.168.0.0/16。

但是，没有跨平台的方法来获取所有的IP地址。在Linux上，可以使用SIOCGIFCONF ioctl。
