Display Hostname and IP address in Python

There are many ways to find the hostname and IP address of a local machine. Here is a simple method to find the hostname and IP address using python code. 
Library used – socket: This module provides access to the BSD socket interface. It is available on all modern Unix systems, Windows, macOS, and probably additional platforms in Python. 

Get Hostname in Python

Method 1: Using the Platform module

The Platform module is used to retrieve as much possible information about the platform on which the program is being currently executed. platform.node() function returns a string that displays the information about the node basically the system’s network name.

Python3

import platform

print(platform.node())

Output: 

GFGNDASM444

Method 2: Using Socket module

Socket programming is a way of connecting two nodes on a network to communicate with each other. One socket(node) listens on a particular port at an IP, while the other socket reaches out to the other to form a connection. The gethostname function retrieves the standard host name for the local computer.

Python3

import socket

print(socket.gethostname())

Output: 

GFGNDASM444

Get IP address in Python

Method 1: Using socket.gethostbyname

The gethostbyname function retrieves host information corresponding to a hostname from a host database.

Python3

import socket

print(socket.gethostbyname(socket.gethostname()))

Output: 

10.143.90.178

Method 2: Using socket.socket instance

Here, two parameters were supplied to a socket instance that was created. AF INET is the first parameter, while SOCK STREAM is the second. AF INET stands for ipv4 address-family. The connection-oriented TCP protocol is referred to as SOCK STREAM.

Python3

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# connect() for UDP doesn't send packets
s.connect(('10.0.0.0', 0))
print(s.getsockname()[0])

Output: 

10.143.90.178

Display Hostname and IP address in Python

We are using the same code which is explained above. Here we compile the hostname and IP address in one program.

Python3

# 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

# This code is contributed by "Sharad_Bhardwaj".

Output: 

Hostname :   pppContainer
IP :  10.98.162.168
NOTE: Output varies from machine to machine.
