About this tool

Generates unique IPv6 Unique Local Addresses (ULA) formatted according to RFC 4193 standards. These addresses provide a method for creating private, non-routable network identifiers within internal infrastructure, mirroring the function of older private IP address ranges. The tool allows users to construct these specific hexadecimal addressing schemes that begin with the fc00::/7 prefix, facilitating the setup and testing of networks that require local addressing without consuming public IPv6 space. Network engineers, developers, and system administrators utilize this generator when designing or troubleshooting internal network architectures. It is particularly useful for simulating large-scale deployments or configuring isolated test environments where standard public IP addresses are unavailable or undesirable.
