Bulk IP-Address / Reverse DNS Lookup Tool

I’ve created this simple little Google Sheet for conducting reverse DNS / IP address lookup via Google Sheets.

I primarily use this tool for auditing the top IP addresses connecting to my site. If you use this API for your own products, please include your website/contact in the URL.

The sheet works off of an API hosted by me so if you have any requests or if you just enjoy using the free tool, please leave me a comment below.
