使用Python查找本地IP地址';s标准数据库
如何在Python平台中独立地并且仅使用标准库查找本地IP地址(即192.168.x.x或10.0.x.x)使用Python查找本地IP地址';s标准数据库,python,networking,ip-address,Python,Networking,Ip Address,如何在Python平台中独立地并且仅使用标准库查找本地IP地址(即192.168.x.x或10.0.x.x) import socket socket.gethostbyname(socket.gethostname()) 这并不总是有效(在主机名位于/etc/hosts中的计算机上,返回127.0.0.1作为127.0.0.1),gimel显示的是一个反义词,使用socket.getfqdn()。当然,您的计算机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向您发送IP地址之外,没

),gimel显示的是一个反义词,使用socket.getfqdn()
。当然,您的计算机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向您发送IP地址之外,没有任何与平台无关的好方法。例如:。请注意,如果您需要NAT后面的IP地址,除非您连接的计算机也在NAT后面,否则这将不起作用
这里有一个在Linux中有效的解决方案:。我刚刚找到了这个解决方案,但它似乎有点黑客化,不过他们说我在*nix上试过,在windows上也试过,效果很好
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8", 80))
print(s.getsockname()[0])
s.close()
这假设您可以访问internet,并且没有本地代理。您可以使用该模块。仅键入:
pip install netifaces
在命令shell中,它将在默认Python安装中自行安装
然后你可以这样使用它:
from netifaces import interfaces, ifaddresses, AF_INET
for ifaceName in interfaces():
addresses = [i['addr'] for i in ifaddresses(ifaceName).setdefault(AF_INET, [{'addr':'No IP addr'}] )]
print '%s: %s' % (ifaceName, ', '.join(addresses))
在我的电脑上,它打印了:
{45639BDC-1050-46E0-9BE9-075C30DE1FBC}: 192.168.0.100
{D43A468B-F3AE-4BF9-9391-4863A4500583}: 10.5.9.207

{D43A468B-F3AE-4BF9-9391-4863A4500583}:10.5.9.207
本模块的作者声称它应该在Windows、UNIX和Mac OS X上工作。如果您不想使用外部软件包,也不想依赖外部Internet服务器,这可能会有所帮助。这是我在上找到并修改的代码示例,用于返回所需信息:
def getIPAddresses():
from ctypes import Structure, windll, sizeof
from ctypes import POINTER, byref
from ctypes import c_ulong, c_uint, c_ubyte, c_char
MAX_ADAPTER_DESCRIPTION_LENGTH = 128
MAX_ADAPTER_NAME_LENGTH = 256
MAX_ADAPTER_ADDRESS_LENGTH = 8
class IP_ADDR_STRING(Structure):
pass
LP_IP_ADDR_STRING = POINTER(IP_ADDR_STRING)
IP_ADDR_STRING._fields_ = [
("next", LP_IP_ADDR_STRING),
("ipAddress", c_char * 16),
("ipMask", c_char * 16),
("context", c_ulong)]
class IP_ADAPTER_INFO (Structure):
pass
LP_IP_ADAPTER_INFO = POINTER(IP_ADAPTER_INFO)
IP_ADAPTER_INFO._fields_ = [
("next", LP_IP_ADAPTER_INFO),

GetAdaptersInfo = windll.iphlpapi.GetAdaptersInfo
GetAdaptersInfo.restype = c_ulong
GetAdaptersInfo.argtypes = [LP_IP_ADAPTER_INFO, POINTER(c_ulong)]
adapterList = (IP_ADAPTER_INFO * 10)()
buflen = c_ulong(sizeof(adapterList))
rc = GetAdaptersInfo(byref(adapterList[0]), byref(buflen))
if rc == 0:
for a in adapterList:
adNode = a.ipAddressList
while True:
ipAddr = adNode.ipAddress
if ipAddr:
yield ipAddr
adNode = adNode.next
if not adNode:
break
用法:
>>> for addr in getIPAddresses():
>>> print addr
192.168.0.100
10.5.9.207
由于它依赖于Windell,因此只能在Windows上使用。作为名为
myip
的别名:
alias myip="python -c 'import socket; print([l for l in ([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith(\"127.\")][:1], [[(s.connect((\"8.8.8.8\", 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0])'"
import socket
print([l for l in ([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")][:1], [[(s.connect(('8.8.8.8', 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0])
import socket
print((([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")] or [[(s.connect(("8.8.8.8", 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) + ["no IP found"])[0])
- 可与Python2.x、Python3.x、现代和旧Linux发行版、OSX/macOS和Windows正确配合使用,以查找当前IPv4地址
- 对于具有多个IP地址、IPv6、没有配置IP地址或没有internet访问的计算机,将不会返回正确的结果
- 据报道,这在最新版本的macOS上不起作用
与上面相同,但仅Python代码:
alias myip="python -c 'import socket; print([l for l in ([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith(\"127.\")][:1], [[(s.connect((\"8.8.8.8\", 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0])'"
import socket
print([l for l in ([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")][:1], [[(s.connect(('8.8.8.8', 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0])
import socket
print((([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")] or [[(s.connect(("8.8.8.8", 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) + ["no IP found"])[0])
- 如果没有配置IP地址,这将引发异常
也可在没有internet连接的LAN上工作的版本:
alias myip="python -c 'import socket; print([l for l in ([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith(\"127.\")][:1], [[(s.connect((\"8.8.8.8\", 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0])'"
import socket
print([l for l in ([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")][:1], [[(s.connect(('8.8.8.8', 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) if l][0][0])
import socket
print((([ip for ip in socket.gethostbyname_ex(socket.gethostname())[2] if not ip.startswith("127.")] or [[(s.connect(("8.8.8.8", 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]]) + ["no IP found"])[0])
(谢谢)
背景: 在这里使用
socket.gethostbyname(socket.gethostname())
不起作用,因为我所在的一台计算机有一个/etc/hosts
,其中包含重复的条目和对自身的引用socket.gethostbyname()
仅返回/etc/hosts
中的最后一个条目
这是我最初的尝试,删除了所有以“127”开头的地址。
:
导入套接字
打印([socket.gethostbyname_ex(socket.gethostname())[2]中的ip,如果不是ip.startswith(“127”)[:1])
这适用于Linux和Windows上的Python 2和3,但不适用于多个网络设备或IPv6。然而,它在最近的Linux发行版上停止了工作,所以我尝试了这种替代技术。它试图连接到位于8.8.8.8
端口53
的Google DNS服务器:
导入套接字
在[socket.socket(socket.AF_INET,socket.SOCK_DGRAM)][0][1]中为s打印([(s.connect(('8.8.8.8',53))、s.getsockname()[0],s.close())
然后,我将上述两种技术组合成一个可以在任何地方使用的一行程序,并在这个答案的顶部创建了myip
alias和Python代码段
随着IPv6的日益普及,对于具有多个网络接口的服务器,使用第三方Python模块查找IP地址可能比此处列出的任何方法都更可靠。im使用以下模块:
#!/usr/bin/python
# module for getting the lan ip address of the computer
import os
import socket
if os.name != "nt":
import fcntl
import struct
def get_interface_ip(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
return socket.inet_ntoa(fcntl.ioctl(
s.fileno(),
0x8915, # SIOCGIFADDR
struct.pack('256s', bytes(ifname[:15], 'utf-8'))
# Python 2.7: remove the second argument for the bytes call
)[20:24])
def get_lan_ip():
ip = socket.gethostbyname(socket.gethostname())
if ip.startswith("127.") and os.name != "nt":
interfaces = ["eth0","eth1","eth2","wlan0","wlan1","wifi0","ath0","ath1","ppp0"]
for ifname in interfaces:
try:
ip = get_interface_ip(ifname)
break;
except IOError:
pass
return ip
使用windows和linux进行测试(不需要额外的模块)
用于单个基于IPv4的LAN中的系统
接口名称的固定列表不适用于最新的linux版本,正如所指出的,这些版本采用了systemd v197关于可预测接口名称的更改。
在这种情况下,您需要手动将列表替换为系统上的接口名称,或使用其他解决方案,如。FYI我可以验证该方法:
import socket
addr = socket.gethostbyname(socket.gethostname())
在OS X(10.6,10.5)、Windows XP和管理良好的RHEL department服务器上工作。它在一个非常小的CentOS虚拟机上不起作用,我只是对它进行了一些内核攻击。因此,对于该实例,您只需检查127.0.0.1地址,在这种情况下,请执行以下操作:
if addr == "127.0.0.1":
import commands
output = commands.getoutput("/sbin/ifconfig")
addr = parseaddress(output)
然后从输出中解析ip地址。应该注意的是,默认情况下ifconfig不在普通用户的路径中,这就是我在命令中给出完整路径的原因。我希望这有帮助。我在我的ubuntu机器上使用它:
import commands
commands.getoutput("/sbin/ifconfig").split("\n")[1].split()[1][5:]
这不起作用。通过命令行utils生成“干净”输出的一种简单方法:
import commands
ips = commands.getoutput("/sbin/ifconfig | grep -i \"inet\" | grep -iv \"inet6\" | " +
"awk {'print $2'} | sed -ne 's/addr\:/ /p'")
print ips
它将显示系统上的所有IPv4地址。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。您可以针对专用网络对其进行筛选—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IP地址。在Linux上,您可以使用ioctl。套接字API方法 看 缺点:
- 不要跨平台
- 需要更多回退代码,与internet上特定地址的存在相关
- 如果您支持NAT,这也不起作用
- 可能会创建UDP连接,而不是独立于(通常是ISP的)DNS可用性(有关使用8.8.8.8:Google的想法,请参阅其他答案)
