Python gets a summary of the native local IP address methods under Windows and Linux

This example summarizes python's approach to getting native local IP addresses under Windows and Linux. Share with you for your reference. Specific analysis is as follows:

Python sockets contain a wealth of functions and methods to get the native IP address information, socket object gethostbyname method can get the native IP address according to the host name, socket object gethostbyname_ex method can get the native IP address list

The first method is obtained by the socket.gethostbyname method

import socket
localIP = socket.gethostbyname(socket.gethostname())# Get the local ip
print "local ip:%s "%localIP

The results are as follows:

'172.16.34.102'

Second method: get a list of native hostnames and IP addresses through the socket.gethostbyname_ex method

import socket
ipList = socket.gethostbyname_ex(socket.gethostname())
print(ipList)

The results are as follows:

(' China - 43226208 - c ', [], [' 192.168.5.196 '])

Both of these methods are also available under Linux, which also gets the native IP address through the following code

import socket
import fcntl
import struct
def get_ip_address(ifname):
  s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
  return socket.inet_ntoa(fcntl.ioctl(
    s.fileno(),
    0x8915, # SIOCGIFADDR
    struct.pack('256s', ifname[:15])
  )[20:24])
