ip address and host name

import socket
try: 
        my_host = socket.gethostname() 
        my_ip = socket.gethostbyname(my_host) 
        print("Hostname :  ",my_host) 
        print("IP : ",my_ip) 
except: 
        print("Unable to get Hostname and IP address")

import socket
print("Fully Qualified Domain Name:", socket.getfqdn())

import socket
print(socket.gethostbyname_ex(socket.gethostname()))

Use Case: Web Server Monitoring

When setting up or monitoring a web server, retrieving the hostname and IP address can be essential for debugging or configuring network settings. This can help in identifying server locations, resolving domain names, or diagnosing network issues during deployment.

Error Handling with socket

Handle common errors like socket.gaierror when network-related issues occur. For example, if the host can't be resolved, using a try-except block can prevent crashes:

import socket
try:
    print(socket.gethostbyname('invalid.host'))
except socket.gaierror as e:
    print(f"Error: {e}")
