How to Find the IP Address of a Website in Linux

When working with websites or web servers, it’s often necessary to find a website’s IP address. This can be useful for troubleshooting, monitoring, or simply understanding how the Internet works. If you’re using a Linux operating system, there are several ways to find a website’s IP address through the command line.

This article will discuss some of the most common and effective methods for finding a website’s IP address in Linux.

What is an IP Address?

An IP (Internet Protocol) address is a unique identifier assigned to every device connected to a network, including servers hosting websites. It acts as the “location” of a particular server, allowing other devices to find and communicate with it. When you visit a website, the domain name (like www.example.com) is resolved to an IP address by the DNS (Domain Name System).

Why Would You Need to Find a Website’s IP Address?

There are several reasons why you might need to find a website’s IP address:

Network Troubleshooting: If a website isn’t loading, knowing its IP address allows you to ping the server or perform other network diagnostics.

Security Testing: Security professionals may need to find an IP address to conduct tests like port scanning or check for vulnerabilities.

Bypassing Domain Restrictions: Some users may want to access a website by its IP if the domain name is blocked, but the server itself isn’t.

How to Find the IP Address of a Website in Linux

You can use several methods to discover a website’s IP address in Linux. Each involves using different command-line utilities built into most Linux distributions.

1. Using the ping Command

The ping command is the simplest and most commonly used method to find a website’s IP address. Here’s how: Open your terminal.

Type the following command, replacing “example.com” with the domain name of the website you’re interested in:

ping example.com

Press Enter.

You’ll see a response from the server showing its IP address. For example:

PING example.com (93.184.216.34): 56 data bytes 64 bytes from 93.184.216.34: icmp_seq=0 ttl=56 time=10.145 ms

In this case, the IP address of “example.com” is 93.184.216.34.

2. Using the nslookup Command

Another standard tool to resolve domain names into IP addresses is nslookup, which queries DNS servers for the domain information. Here’s how to use it:

Open your terminal.

Type the following command:

nslookup example.com

Press Enter.

You’ll receive a response that includes the IP address of the website:

Server: 8.8.8.8 Address: 8.8.8.8#53

Non-authoritative answer: Name: example.com Address: 93.184.216.34

In this case, the IP address for “example.com” is 93.184.216.34.

3. Using the dig Command

The dig (Domain Information Groper) command is a powerful tool for querying DNS servers, and it can also be used to find the IP address of a website. It provides more detailed information than ping or nslookup. Here’s how to use dig:

Open your terminal.

Type the following command:

dig example.com

Press Enter.

The output will include a section called “ANSWER SECTION,” which will display the IP address of the domain:

; ANSWER SECTION:

example.com. 86400 IN A 93.184.216.34

Again, the IP address is 93.184.216.34.

4. Using the host Command

The host command is another simple utility to find the IP address of a website by querying DNS servers. Here’s how to use it:

Open your terminal.

Type the following command:

host example.com

Press Enter.

You’ll receive an output like this: example.com has address 93.184.216.34

This shows the IP address of “example.com” as 93.184.216.34.

5. Using Online Tools

If you prefer a graphical approach or cannot access a Linux terminal, many online tools can help you find a website’s IP address. Websites like IPvoid, WhatsMyDNS, and MXToolbox allow you to enter a domain name and instantly retrieve its associated IP address.
