Random IP generator
Random IP addresses for test data, inside whatever range you need.
Veelgestelde vragen
Which range should I use for test data?
The documentation ranges, if the data will ever be seen by anyone else. 192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24 are reserved by RFC 5737 for examples and cannot route on the real internet, so they can never point at somebody’s actual machine. The IPv6 equivalent is 2001:db8::/32.
Why not just make up an address?
Because almost every address you invent belongs to somebody. Writing 12.34.56.78 in a tutorial or a test fixture points at a real host, and screenshots of real addresses end up in search results. That is exactly what the documentation ranges exist to avoid.
Are these random enough for security use?
They come from your browser’s cryptographic random number generator, so they are not predictable. But random addresses are test data, not a security measure — nothing here should be used as a token, a key or an identifier.
