Reverse DNS Search Web Tool Tutorial

Reverse DNS Search allows you to retrieve domain name properties connected by DNS records. For instance, you can find web properties all hosted on a given IP address or using the same nameserver and mail server.

In this tutorial, we tackle:

Connected Domain Search Methods

The tool has four search methods.

1. Obtain Connected Domains

If you only have a domain name to work with, you can use it as a search string by typing it into the search field and clicking Search.

The tool will return a maximum of 300 connected domains, displayed onscreen by page. Click on the page numbers at the bottom right to view the rest of the domains. These domains are hosted on the same IP address as the domain you typed into the search field.

You can also retrieve domains resolving to an IP address using the Search by IP address option. Type the IP address into the search field and click Search.

Manage the Search Results Views

Only the first 300 domain names will be displayed for all four search methods discussed above. But, as mentioned, the Load more DNS records button gives you the option to retrieve more connected domains.

Each batch of records is displayed by page, with 30 records per page by default. You can toggle to the next page by clicking the page number at the bottom of the search results.

However, you can also customize the number of domains you can view on a single page by toggling Show at the bottom. You can then select 30, 70, or 150 domains. You can also show All domains at once.
