IP address by Domain Name

I am trying to get IP address of a domain.. i am using following code

>> import socket
>> socket.gethostbyname('www.google.com')

its giving me following error..

Traceback (most recent call last):
  File "<pyshell#18>", line 1, in <module>
    socket.gethostbyname('www.google.com')
gaierror: [Errno 11001] getaddrinfo failed

what is wrong with my code...is there an开发者_开发知识库y other way to get ip address by domain name in python..??? please help...

Your code is correct. Perhaps you have a firewall in between you and these servers that is blocking the request?

import socket
domainName = input('Enter the domain name: ')
print(socket.gethostbyname(domainName))

I think you forgot to print it because it works for me.

# Python3 code to display hostname and 
# IP address 

# Importing socket library 
import socket 

# Function to display hostname and 
# IP address 
def get_Host_name_IP(): 
    try: 
        host_name = socket.gethostname() 
        host_ip = socket.gethostbyname(host_name) 
        print("Hostname : ",host_name) 
        print("IP : ",host_ip) 
    except: 
        print("Unable to get Hostname and IP") 

# Driver code 
get_Host_name_IP() #Function call

That error also appears when the domain is not hosted anywhere (is not connected to any IP, any nameserver) or simply does not exist.

Here is full example, how you can get IP address by Domain Name.

import urllib.parse
import socket
import dns.resolver

def get_ip(target):
    try:
        print(socket.gethostbyname(target))
    except socket.gaierror:
        res = head(target, allow_redirects=True)
        try:
            print(r.headers['Host'])
        except KeyError:
            parsed_url = urllib.parse.urlparse(target)
            hostname = parsed_url.hostname
            try:
                answers = dns.resolver.query(hostname, 'A')
                for rdata in answers:
                    print(rdata.address)
            except dns.resolver.NXDOMAIN:
                print('ip not found')

get_ip('example.com')
