Enter any CIDR block to instantly convert it into a complete IP address range showing the first IP, last IP, and total number of addresses. Browse the full list of IPs in your subnet range, export results, and verify your CIDR to IP range conversions for firewall rules, access control lists, and network allocation planning. Run the visual subnet calculator to produce a visual VLSM map for a network design presentation or IP address planning document.
