Python script to get device vendor name from MAC Address

Last Updated : 07 Sep, 2022

A MAC address is a unique identity of a network interface that is used to address the device in a Computer Network.

What does MAC Address consist of?

A MAC address is made up of 12 hexadecimal digits, 6 octets separated by ':'. There are 6 octets in a MAC address. In the first half, the manufacturer info is stored.

MAC-Address

How do we get the Manufacturer details?

For this article, we will be using an API that will fetch the MAC Address for us. We will use a Python script to automate the fetching process so that we can use it later in the Softwares and websites that may require this functionality.

We will use requests module to work with this API.

Below is the implementation.

Python3

import requests import argparse  print("[*] Welcome")  # Function to get the interface name def get_arguments():        # This will give user a neat CLI     parser = argparse.ArgumentParser()          # We need the MAC address     parser.add_argument("-m", "--macaddress",                         dest="mac_address",                         help="MAC Address of the device. "                         )     options = parser.parse_args()          # Check if address was given     if options.mac_address:         return options.mac_address     else:         parser.error("[!] Invalid Syntax. "                      "Use --help for more details.")   def get_mac_details(mac_address):          # We will use an API to get the vendor details     url = "https://api.macvendors.com/"          # Use get method to fetch details     response = requests.get(url+mac_address)     if response.status_code != 200:         raise Exception("[!] Invalid MAC Address!")     return response.content.decode()  # Driver Code if __name__ == "__main__":     mac_address = get_arguments()     print("[+] Checking Details...")          try:         vendor_name = get_mac_details(mac_address)         print("[+] Device vendor is "+vendor_name)     except:                # Incase something goes wrong         print("[!] An error occurred. Check "               "your Internet connection.")
