IP Domain Lookup Tool

Job ID: 39927697

Budget: $10 – $30 USD

I’m building a tiny web utility where I can type an IPv4 address into a single text field, hit “Go”, and instantly see every domain hosted on that IP. The interface must stay strictly minimalist: just the field, the button, and the results table.

Functional scope
• Results should list the domain names only—no hosting or registration extras.
• Extras I do need:
– Copy-to-clipboard button for the full list
– One-click download of the list as a CSV file
– Simple keyword search to filter the results in real time

Feel free to choose the back-end stack that lets you query reverse-IP records quickly and reliably (Python, PHP, Node, or similar are all fine); just keep the front end clean and fast.

Acceptance
I’ll consider the job complete when I can deploy the code on my server, enter an IP, and:
1. See the domain list appear within a reasonable delay.
2. Copy it to the clipboard with one click.
3. Download an accurate CSV.
4. Filter the table instantly as I type.
