How to Get Domain Name Information in Python?

Domain names are a fundamental aspect of the internet.

They serve as unique identifiers for websites and web services on the internet.

In Python, you can easily retrieve information about a domain name using the built-in socket module.

In this blog post, we will discuss how to get domain name information in Python using the socket module.

How to get domain name information in Python using the socket module

Step 1: Import the socket Module

The first step in getting domain name information is to import the socket module. The socket module provides access to various network-related functions, including resolving domain names to IP addresses.

import socket

Step 2: Use the gethostbyname() Function

The gethostbyname() function is used to resolve a domain name to an IP address. The function takes a domain name as its argument and returns the IP address associated with the domain name. Here's an example:

ip_address = socket.gethostbyname("www.example.com")
print(ip_address)

Output:

93.184.216.34

In this example, we passed the domain name "www.example.com" to the gethostbyname() function, which returned the IP address associated with the domain name.

Step 3: Use the gethostbyaddr() Function

The gethostbyaddr() function is used to resolve an IP address to a domain name.

The function takes an IP address as its argument and returns the domain name associated with the IP address.

Here's an example:

domain_name = socket.gethostbyaddr("93.184.216.34")
print(domain_name)

Output:

('e.root-servers.net', ['e.root-servers.net'], ['192.203.230.10'])

In this example, we passed the IP address "93.184.216.34" to the gethostbyaddr() function, which returned the domain name associated with the IP address.

Step 4: Use the getaddrinfo() Function

The getaddrinfo() function is used to retrieve detailed information about a domain name. The function takes a domain name and a port number as its arguments and returns a list of tuples containing information about the domain name. Here's an example:

info = socket.getaddrinfo("www.example.com", 80)
print(info)

Output:

[(<AddressFamily.AF_INET: 2>, <SocketType.SOCK_STREAM: 1>, 6, '', ('93.184.216.34', 80))]

In this example, we passed the domain name "www.example.com" and port number 80 to the getaddrinfo() function, which returned a list of tuples containing information about the domain name.

Conclusion

In this blog post, we discussed how to get domain name information in Python using the socket module.

We used the gethostbyname(), gethostbyaddr(), and getaddrinfo() functions to retrieve IP addresses, domain names, and detailed information about domain names.

By using these functions, you can easily access and manipulate domain name information in Python.
