If you need to know the IP address of a remote machine, you can use a built-in library function, gethostbyname(). In this case, you need to pass the remote hostname as its parameter.
In this case, we need to call the gethostbyname() class function. Let's have a look at this short code snippet.
Listing 1.2 shows how to get a remote machine's IP address as follows:
#!/usr/bin/env python # Python Network Programming Cookbook, Second Edition
-- Chapter - 1 # This program is optimized for Python 2.7.12 and
Python 3.5.2. # It may run on any other version with/without
modifications. import socket def get_remote_machine_info(): remote_host = 'www.python.org' try: print ("IP address of %s: %s" %(remote_host,
socket.gethostbyname(remote_host))) except socket.error as err_msg: print ("%s: %s" %(remote_host, err_msg)) if __name__ == '__main__': get_remote_machine_info()
If you run the preceding code it gives the following output:
$ python 1_2_remote_machine_info.py IP address of www.python.org: 151.101.36.223
