Fake IP Address Generator
Used by developers, writers, and creators worldwide.
A fake IP address generator produces random IPv4 and IPv6 addresses for testing, sample data, and documentation. When you build or test code that parses, validates, logs, or geolocates IP addresses, you need realistic but meaningless addresses rather than exposing real ones. This tool generates correctly formatted addresses in either version, so you can seed test fixtures, mock request logs, or example configuration in seconds. Choose a version and how many you want, then copy them in. It is ideal for testing IP validation, building mock analytics, and writing documentation. The addresses are random and not tied to any real host, which makes them safe to share — though if you need addresses in a specific private range or subnet, you may want to constrain them in your own code. For most testing, a varied batch of well-formed addresses is exactly what you need to exercise your logic.

FAQ
what is the difference between IPv4 and IPv6
IPv4 uses four numbers from 0 to 255 separated by dots, like 192.0.2.1, while IPv6 uses eight groups of hexadecimal digits separated by colons. IPv6 exists because the world ran out of available IPv4 addresses.
are these real IP addresses
They are randomly generated and not tied to any real host, so they are safe to use in tests and docs. They follow the correct format for each version, which is what matters for exercising parsing and validation logic.
can i get addresses in a specific range
This tool generates addresses across the full range. If you need a particular private range or subnet — say, a 10.x or 192.168.x block — it is easy to constrain the output in your own code once you have the format.
