from bs4 import BeautifulSoup as bs


#### ip myPC
myHostName = socket.gethostname()
myIPinfo = socket.gethostbyname_ex(myHostName)

#### public ip
def findIP():
	pubIP1 = requests.get("https://api.ipify.org").text
	res = requests.get('https://api.findip.kr')
	soup = bs(res.text, 'html.parser')
	pubIP2 = soup.select_one('body').getText().split()
	return pubIP2

print("Host Name : {}".format(myHostName))
print("IP lo0 : {}".format(myIPinfo[2][0]))
print("IP en0 : {}".format(myIPinfo[2][1]))
print("My pubIP from api.ipify.org : ", pubIP1)
print("My pubIP from api.findip.kr : ", findIP()[10])
