- Populating a firewall rule test.
- Testing IP parsing and validation code.
Frequently asked questions
Are there any usage caps on the Random IP Address Generator?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Is the Random IP Address Generator safe to use with private information?
No. The Random IP Address Generator runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What problem does the Random IP Address Generator solve?
In practice it gets used for three things: generating log test data. Populating a firewall rule test. Testing IP parsing and validation code. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the tool works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
