Random IP generator
Random IP Generator
Generate random IPv4 or IPv6 addresses for testing, sample data, or documentation — including ranges guaranteed to be reserved for examples.
How does this generator work?
Each click produces fresh, cryptographically random addresses in your browser — nothing is sent to a server, logged, or reused. Pick IPv4 or IPv6, choose a range, and copy any result with one click.
Choosing a range
- Any — fully random octets/groups. Looks like a real address, but may overlap with one in actual use.
- Private (LAN) — drawn from
10.0.0.0/8,172.16.0.0/12, or192.168.0.0/16(IPv4 only), the ranges used on home and office networks. - Documentation (TEST-NET) — drawn from
192.0.2.0/24,198.51.100.0/24,203.0.113.0/24(RFC 5737), or2001:db8::/32(RFC 3849) for IPv6. These blocks are permanently reserved for examples and will never be assigned to a real host.
Tip: for screenshots, sample CSV files, or API documentation that must
never accidentally point at a real server, always use the
Documentation (TEST-NET) range.
