IPv4 Lease vs Buy Calculator

Compare the cash outlay of leasing IPv4 address space with purchasing a block using editable acquisition, transfer, and carrying-cost assumptions.

Cash-outlay model

Lease the block, or acquire it?

Purchase assumptions are editable. LogicWeb lease defaults use current theme/billing catalog values where available.

Simple cash break-even—Cumulative lease payments equal modeled purchase outlay.

How to interpret it

Buying creates an asset. Leasing preserves capital.

A simple cash comparison cannot make the decision for you. Purchased IPv4 space may retain resale value, while leasing can reduce upfront capital and procurement complexity. Contract terms, registry eligibility, operational work, and future pricing also matter.

Short or uncertain deploymentLeasing can reduce the cost of committing capital to address space you may not need permanently.

Long, stable requirementOwnership may become attractive when the organization wants the asset and can manage the transfer process.

Operational scopeCompare LOA, RPKI, IRR, rDNS, geolocation, abuse handling, and support—not only the raw address line item.

Editable inputs

Use a real acquisition quote before deciding.

The default purchase-price inputs are only starting assumptions for modeling. Replace them with a current broker, marketplace, or direct-holder quote. Transfer, escrow, legal, registry, and internal operating costs should also be replaced with your actual figures.

The calculator intentionally ignores resale value.That makes the output a cash-outlay comparison, not an accounting valuation or investment-return model.Review the planning benchmark
