How to perform a reverse IP lookup | The Ultimate Guide Published: 25 Mar, 2023
Understanding the intricacies of network communication is crucial. One of the fundamental aspects of network communication is the use of IP addresses. Every device on a network has a unique IP address, which serves as its identifier. While it's essential to understand the IP addresses assigned to your devices, it's equally important to understand how to perform a reverse IP lookup. In this article, we will try to answer the question: How to perform a reverse IP lookup? And answering it extensively to serve as evidence about reverse IP lookup.
How to perform a reverse IP lookup?
A reverse IP lookup is a technique that allows you to identify the domain name associated with a specific IP address lookup. It's the opposite of a traditional IP lookup, which uses a domain name to identify the corresponding IP address. A reverse IP lookup is beneficial when troubleshooting network issues or investigating potential security threats.
When performing a reverse IP lookup, you can discover the names of websites hosted on a particular server, the Internet Service Provider (ISP) responsible for managing the IP address, and other critical information. This data can help you identify the source of network problems, identify potential security threats, or discover additional information about a domain name.
Now that you understand the importance of a reverse IP lookup let's delve into how it works and the tools you can use to perform it.

Performing a reverse IP lookup using command-line tools
If you prefer to use command-line tools, there are several options available, including nslookup and dig. Here's an introduction to these tools and a step-by-step guide for using them to perform a reverse IP lookup:
Introduction to command-line tools such as nslookup and dig:
Nslookup and dig are both command-line tools that are commonly used for DNS-related tasks. These tools can be used to perform a reverse IP lookup by querying a DNS server for information about the IP address in question.
Nslookup is a command-line tool that is included with Windows operating systems. It's used to query DNS servers and obtain information about domain names, IP addresses, and other DNS records. Dig is a similar command-line tool that is commonly used on Unix-based systems.
Step-by-step guide for using command-line tools to perform a reverse IP lookup:
Step 1: Open a command prompt on your computer. On Windows, you can do this by pressing the Windows key + R and typing "cmd" in the Run dialog box. On Mac or Linux, open a terminal window.
Step 2: Type "nslookup" or "dig" followed by the IP address you want to perform a reverse lookup on. For example, if you want to perform a reverse lookup on the IP address 192.168.1.1, you would type "nslookup 192.168.1.1" or "dig -x 192.168.1.1" and press Enter.
Step 3: Review the results. The tool will provide you with information such as the domain name associated with the IP address and the IP addresses of the nameservers for the domain name.
Step 4: Use the information obtained to troubleshoot any network issues or investigate potential security threats.
Command-line tools such as nslookup and dig can be used to perform a reverse IP lookup by querying a DNS server for information about the IP address in question. These tools are especially useful for IT professionals who prefer to work from the command line.
What is the difference between IP lookup and reverse IP lookup?
The main difference between IP lookup and reverse IP lookup is that IP lookup looks up information about a specific IP address, while reverse IP lookup looks up all the domain names associated with a specific IP address.
An IP lookup is a process of translating between IP addresses and internet domain names. Forward IP address lookup converts an internet name to an IP address. Reverse IP address lookup converts the IP address number to the name. For most computer users, this process occurs behind the scenes.
IP lookup is often used to investigate the source of suspicious network traffic or to identify the location of a server or device on the internet. It can also be used for geolocation services to deliver location-specific content or advertising to users.
A reverse DNS look up is a very simple query against the DNS system. A reverse IP look up is a very complex search database that has recorded the IP addresses of web sites it has crawled. The result being a list of websites hosted at that IP address.
Reverse IP lookup is often used by website owners or administrators to identify all the domains hosted on a particular server. This can be helpful in managing and troubleshooting issues with multiple domains hosted on the same server.
How do I reverse lookup a computer name by IP address?
You can perform a reverse lookup on an IP address using nslookup command. To perform a reverse lookup on an IP address 75.126.153.206, enter (open MS-DOS prompt by clicking on Start > Run > Type > Cmd.exe): nslookup 75.126.153.206 Server: localhost Address: 127.0.0.1 Name: www.cyberciti.biz Address: 75.126.153.206
How do I find out what is behind an IP address?
You can use ARIN WHOIS to view ownership if you know the IP address1. To find an IP address, open Windows command prompt ( Start + CMD on Windows) > type ping websitename.com1. You can also use Register.com, GoDaddy, or DomainTools to find an IP address owner if you don’t know the IP address
Conclusion
Performing a reverse IP lookup can be a valuable tool for IT administrators and security professionals. By identifying the organization that owns an IP address, you can potentially uncover other associated IP addresses or domain names, as well as investigate network issues.
In this blog post, we have discussed the importance of performing a reverse IP lookup and provided step-by-step guides for performing a reverse IP lookup using both online tools and command-line tools. We have also provided a comparison of different tools and their features.
