ABTdomain Tools

ABTdomain's Reverse Nameserver Lookup allows you to find all domains that use a specific nameserver. This is useful for identifying domains hosted by the same provider or sharing the same DNS infrastructure. Results are limited to a maximum of 17 domains.

Simply enter a nameserver in the search box above (e.g., ns1.example.com) and click "SEARCH DOMAINS" to find all domains using that nameserver.

The results from this tool are based on a **periodic snapshot of official registry data**, which we process and update in our own database. This means:

• The data is not real-time. Searching the same nameserver repeatedly throughout the day will return the same results from our last database update.
• The list is not exhaustive. For operational and compliance reasons, our service does not provide a complete, downloadable list of every domain on a nameserver.

This tool is designed for directional research and analysis based on our processed dataset, not for real-time monitoring or comprehensive data extraction.

Yes, ABTdomain's Reverse Nameserver Lookup tool is completely free to use. You can search nameservers without any cost or registration required. However, please do not abuse the service, as excessive usage may result in a temporary IP ban.

This tool is free for manual, individual searches for legitimate research purposes. The following activities are strictly prohibited:

• No Automated Scraping: Using any automated means to systematically query our service or extract data.
• No Data Resale or Redistribution: You may not repackage, resell, or create a competing service with the data obtained from our tool.
• No Malicious Use: Using the data for spamming, unauthorized security scanning, or any form of harassment is forbidden.

Violation of these terms will result in a permanent IP ban.
