Generates random IPv4 addresses. The "Private" option generates addresses from the RFC 1918 private ranges (10.x.x.x, 172.16-31.x.x, 192.168.x.x). Useful for testing, dummy data, and network documentation. Runs entirely in your browser.
Random IP Address Generator: create realistic network data for your testing environments with our versatile IPv4 tool. Whether you need a public IP generator for log simulation or a private IP range for local network documentation, this utility delivers high-quality results directly in your browser. All addresses are sampled from valid ranges, ensuring your test data mirrors real-world network traffic patterns while keeping your configuration private.
Our generator handles all standard private address spaces defined in RFC 1918, including the 10.x.x.x, 172.16.x.x, and 192.168.x.x blocks. This makes it an essential subnet tool for developers and sysadmins who need to populate network fixtures or simulate internal server addresses. By using client-side JavaScript, the tool ensures fast performance and immediate output for bulk generation tasks. Whether you're building a network simulation or just need some dummy IP data, our random ipv4 utility is the perfect solution.
Anything that is not in the RFC 1918 private space (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16), the loopback (127/8), the link-local 169.254/16 block, or the multicast 224/4 block. The result is a plausible routable IPv4.
No. The IPv4 space has been almost entirely assigned to real organisations for over a decade. Random "public" IPs will hit real hosts - never use them for traffic, only for test data and fixtures.
Provide a CIDR block (for example 198.51.100.0/24) and the tool samples uniformly across the host portion. /32 returns the single address; /0 covers the whole space.
IPv6 random generation is a different problem (128-bit addresses, different reserved ranges, formatting choices around :: and zero-compression). It deserves its own dedicated tool rather than being bolted onto an IPv4 page.
