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

对于linux,你可以使用hostname -I system命令的check_output,就像这样:

from subprocess import check_output
check_output(['hostname', '-I'])

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)]

对于*nix系统上的IP地址列表,

import subprocess
co = subprocess.Popen(['ifconfig'], stdout = subprocess.PIPE)
ifconfig = co.stdout.read()
ip_regex = re.compile('((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-4]|2[0-5][0-9]|[01]?[0-9][0-9]?))')
[match[0] for match in ip_regex.findall(ifconfig, re.MULTILINE)]

虽然现在回答这个问题有点晚了,但我认为其他人可能会发现它有用:-)

PS:它会返回广播地址和网络掩码。

Pyroute2是一个很棒的库,不仅可以用来获取IP地址,还可以用来获取网关信息和其他有用的信息。 下面的代码可以获取任意接口的ipv4地址。

from pyroute2 import IPRoute
ip = IPRoute()

def get_ipv4_address(intf):
    return dict(ip.get_addr(label=intf)[0]['attrs'])['IFA_LOCAL']

print(get_ipv4_address('eth0'))
import netifaces as ni 

ni.ifaddresses('eth0')
ip = ni.ifaddresses('eth0')[ni.AF_INET][0]['addr']
print(ip)

这将返回你的IP地址在Ubuntu系统和MacOS。输出将是系统IP地址,如我的IP: 192.168.1.10。

在Debian上(经过测试),我怀疑大多数Linux ..

import commands

RetMyIP = commands.getoutput("hostname -I")

在MS Windows上(已测试)

import socket

socket.gethostbyname(socket.gethostname())
