я пытаюсь разобраться с простым сканером портов, и код:

 import socket as s
from IPy import IP
def scan(ip):
    ipc=controllo(target)
    print("scanning: "   str(ipc))
    for port in range(75,85):
        port_scanner(ipc, port)
def controllo(ip):
    try:
        IP(ip)
        return(ip)
    except ValueError:
        return s.gethostbyname(ip)
def port_scanner(ipa, port):
    try:
       sock=s.socket()
       sock.settimeout(0.5)
       sock.connect((ipa, port))
       print("[ ] La porta " str(port) " è aperta ")
    except:
        pass
target=input("inserisci il sito, se desideri inserire più siti, separali con una , : ")
if "," in target:
    for ipaddress in target.split(","):
        scan(ipaddress.strip(" "))

else:
    scan(target)
 

в любом случае, когда я запускаю его, я получаю эту ошибку:

 Traceback (most recent call last):
  File "C:UsersvittoPycharmProjectspythonProject1main.py", line 10, in controllo
    IP(ip)
  File "C:UsersvittoPycharmProjectspythonProject1venvlibsite-packagesIPy.py", line 249, in __init__
    (self.ip, parsedVersion) = parseAddress(ip, ipversion)
  File "C:UsersvittoPycharmProjectspythonProject1venvlibsite-packagesIPy.py", line 1422, in parseAddress
    bytes = [int(x) for x in bytes]
  File "C:UsersvittoPycharmProjectspythonProject1venvlibsite-packagesIPy.py", line 1422, in <listcomp>
    bytes = [int(x) for x in bytes]
ValueError: invalid literal for int() with base 10: 'google'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:UsersvittoPycharmProjectspythonProject1main.py", line 25, in <module>
    scan(ipaddress.strip(" "))
  File "C:UsersvittoPycharmProjectspythonProject1main.py", line 4, in scan
    ipc=controllo(target)
  File "C:UsersvittoPycharmProjectspythonProject1main.py", line 13, in controllo
    return s.gethostbyname(ip)
socket.gaierror: [Errno 11001] getaddrinfo failed
 

как я могу решить эту проблему?
ps: в целевом вводе это итальянский перевод для чего-то вроде:
