Prefixwell IP Plan

Prefixwell helps a network administrator turn a parent IPv4 range into a clear, editable address plan. Create several local plans and enter named host requirements. Prefixwell chooses the smallest LAN subnet that fits each request, allocates it within the parent range, and shows the assigned and free address space on a proportional map. Reserve fixed CIDR blocks for existing equipment or networks, add VLAN labels and notes, and see overlaps, out-of-range reservations, and requests that do not fit before handoff.

Open the full assignment schedule to inspect network, usable address range and capacity. Share a generated multipage PDF handoff sheet or a named CSV file. Plans remain editable and saved on this device. New installs begin empty.

Prefixwell performs offline IPv4 planning arithmetic. It does not scan a network, configure devices, manage DHCP, synchronize with a server, or claim live address availability. Confirm the design against your environment before deployment. There is no account, subscription, advertising, analytics, tracking or developer upload. Your plans stay on this device unless you choose to share an export.
