What is Reverse Domain Lookup Tool

Usage of Reverse Domain Lookup Tool


Incident Response and Threat Intelligence

Whether responding to an incident, identifying a botnet C2, or simply tracking down the Internet with noise scanning, a reverse IP lookup can identify hostnames attached to an attacking system. These findings can further inform the investigation and lead to additional information sources.

Oversubscribed Web Hostings

When purchasing web hostings in a shared hosting environment, the web host provider sells small amounts of resources on a web server to a number of websites. To cut costs, the web host provider may oversubscribe, that is, sell more websites than the server can handle. This is common in cheaper shared hosting companies, where a single web server can host thousands of small websites. Using the reverse IP lookup you can identify how many sites you are sharing that host with.

Web Hosting Reputation

Hosts with poor reputations can affect email delivery, blacklisting of your site, and search engine ranking. Use the reverse IP address lookup service to identify other sites on your host. Next, use investigative tools to identify if these other hosts are of poor quality, perhaps even spam or phishing sites.

Why do we need reverse DNS lookup?

Reverse DNS is mainly used to track the origin of a website visitor, the origin of an e-mail message, etc. It is usually not as critical as the classic DNS, visitors will reach the website even without the presence of reverse DNS for the IP of the web server or the IP of the visitor.
