Every business that needs more IPv4 space eventually hits the same fork: lease it, or buy it outright. There’s no universally correct answer — but there is a wrong way to decide, which is picking based on which option sounds more permanent rather than what your actual usage pattern needs.
What the Choice Actually Comes Down To
Buying IPv4 addresses is a permanent ARIN or RIPE ownership transfer — you pay a market rate per address, the block becomes a registered asset in your name, and you hold it indefinitely. Leasing gives you the right to announce and use a block for a fixed term — typically month-to-month, 6 months, or 12 months — without the upfront capital outlay of a purchase.
The honest framing: buying is a capital decision, leasing is an operating decision. Which one is right depends on how long you actually need the space and how certain you are about that timeline.
1. The Capital Difference Is Larger Than People Expect
IPv4 addresses currently trade in the secondary market at prices that make a /24 (256 addresses) purchase a meaningful five-figure capital expense, paid up front, before you’ve used a single address. Leasing the same /24 turns that into a predictable monthly operating cost instead.
Mobosoft insight: At our flat $0.50 per IP per month rate, a /24 leases for $128/month — compare that to the up-front cost of buying the same block outright, and the breakeven point for most businesses is measured in years, not months.
2. Buying Makes Sense When Your Need Is Permanent and Sizable
If you know with confidence that you will need a specific amount of IPv4 space indefinitely — you’re a hosting provider building out permanent infrastructure, or an enterprise consolidating addressing for the long haul — owning the block means no renewal risk, no lease-end negotiation, and a registered asset that (market conditions permitting) may hold or appreciate in value.
Buying also makes sense if you specifically need full transfer of registration rights, not just usage rights — for example, if you’re required to demonstrate direct ownership for compliance or contractual reasons.
3. Leasing Makes Sense When You Need Flexibility or Are Testing Scale
Leasing is the better fit when your address needs might change — you’re scaling a new product, testing BYOIP into a cloud provider before committing further, or running a project with a defined end date. It’s also the practical choice when you don’t want to tie up capital in an asset whose long-term value depends on IPv6 adoption trends nobody can predict precisely.
Mobosoft insight: Most of what we lease goes to hosting providers and cloud operators bringing space into AWS, GCP, or Azure via BYOIP — they want the cost savings on cloud provider IPv4 charges without the capital commitment of owning the block outright.
4. Leasing Gets You Moving Faster
A purchase involves registry transfer approval, which can take longer and depends on the seller’s registry standing and the transfer policies of ARIN, RIPE, or whichever registry holds the block. A lease from a provider who already holds clean, registry-allocated space can be live substantially faster.
Mobosoft insight: Because we lease from our own existing ARIN and RIPE allocations rather than brokering someone else’s block, we issue the LOA plus ROA and IRR route objects within one business day of a signed agreement — no transfer approval to wait on.
5. You Can Change Your Mind Later
One thing people underestimate: leasing now doesn’t lock you out of buying later. Plenty of businesses lease space to prove out a use case or cover a scaling event, then decide afterward whether to pursue an outright purchase once their long-term need is clear. Buying first and discovering you needed less space is a much harder position to unwind.
The Bottom Line for Growing Businesses
If your IPv4 need is permanent, sizable, and certain, buying can make sense. If there’s any uncertainty about how much space you’ll need or for how long — which describes most growing businesses — leasing gets you the same working, routable address space without the capital risk, and you can always revisit a purchase once your usage pattern is proven out.
Not Sure Which Fits Your Situation?
Mobosoft leases IPv4 blocks — /24, /23, and /22 available directly, larger blocks by request — at a flat, published rate with no long-term lock-in required.
