python mini-program 컴퓨터의 외부 및 내부 IP 확인하기

내부 IP 주소 확인

import socket
 
in_address=socket.gethostbyname(socket.gethostname())
print(in_address)

 

import socket
 
in_address=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
in_address.connect(("www.google.co.kr",443))
print(in_address.getsockname()[0])

 

외부 IP 주소 확인

 

import requests
import re
 
req=requests.get("http://ipconfig.kr")
out_address=re.search(r'IP Address : (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})',req.text)[1]
print(out_address)
 

 

 

내부 IP, 외부 IP 주소 확인

import socket
import requests
import re
 
in_address=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
in_address.connect(("www.google.co.kr",443))
print("내부 IP : ",in_address.getsockname()[0])
 
req=requests.get("http://ipconfig.kr")
out_address=re.search(r'IP Address : (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})',req.text)[1]
print("외부 IP : ",out_address)
