如何找到本地IP地址(即192.168.x。x或10.0.x.x)在Python平台独立,只使用标准库?


当前回答

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

好吧,这是Windows特定的,需要安装python WMI模块,但这似乎比不断尝试调用外部服务器要简单得多。这只是另一种选择,因为已经有很多好的选择,但它可能非常适合您的项目。

Import WMI

def getlocalip():
    local = wmi.WMI()
    for interface in local.Win32_NetworkAdapterConfiguration(IPEnabled=1):
        for ip_address in interface.IPAddress:
            if ip_address != '0.0.0.0':
                localip = ip_address
    return localip







>>>getlocalip()
u'xxx.xxx.xxx.xxx'
>>>

顺便说一下,WMI非常强大……如果你正在做任何窗口机器的远程管理,你一定要看看它能做什么。

简单而甜蜜!

def getip():

    import socket
    hostname= socket.gethostname()
    ip=socket.gethostbyname(hostname)

    return(ip)

这是UnkwnTech的答案的变体——它提供了一个get_local_addr()函数,该函数返回主机的主LAN ip地址。我发布它是因为这增加了一些东西:ipv6支持,错误处理,忽略localhost/linklocal地址,并使用TESTNET地址(rfc5737)来连接。

_local_networks = ("127.", "0:0:0:0:0:0:0:1")

ninjagecko回答的变体。这应该在任何允许UDP广播的LAN上工作,并且不需要访问LAN或internet上的地址。

import socket
def getNetworkIp():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    s.connect(('<broadcast>', 0))
    return s.getsockname()[0]

print (getNetworkIp())
