socket.gaierror: [Errno 11001]

[nemat]

Hi i am still facing the same kind of issue.

Below is my code

import telnetlib
import getpass

p=open("ipadd.txt")

user=input("Please Enter the Username: ")
password=getpass.getpass()


for line in p:
    print("Configuring Switch with IP : "+line)
    HOST=str(line.split())
    tel=telnetlib.Telnet(HOST)

    tel.read_until(b"Username:")
    tel.write(user.encode("ascii")+b"\n")

    if password:
        tel.read_until(b"Password:")
        tel.write(password.encode("ascii")+b"\n")


    tel.write(b"conf t \n")


    for x in range(10,20):
        tel.write(b"vlan "+str(x).encode("ascii")+b"\n")
        tel.write(b"exit \n")
        
    tel.write(b"end \n")
    tel.write(b"wr \n")
    tel.write(b"exit \n")

    print(tel.read_all().decode("ascii"))

p.close()

Here is the output, with error
