Network / IP
Convert an IPv4 range into the smallest CIDR block list.
Converts a start-end IPv4 range into the smallest practical list of CIDR blocks. The output is organized for quick review, copying, and cross-checking with nearby tools in the Network / IP group.
Network tools normalize IP, CIDR, host, or URL input, then calculate ranges or inspect live response metadata. They are useful for checking routing assumptions, allowlists, response headers, redirects, and public network ownership.
Open nearby tools in the same group to cross-check, inspect deeper, or complete a small workflow.
