FAQ
Frequently asked questions
Everything we get asked most often about buying, leasing, selling, tunneling, sponsorship and IPv6, collected in one place.
Most asked
Should I lease or buy IPv4 addresses?
Lease if you would rather not tie up capital, or expect your needs to change, since a leased block can be resized or handed back when its term ends. Buy if the need is permanent and you want the block registered in your own name. Lease to own sits in between: the block is yours after one to five years of monthly payments. Ask, and we quote both routes, so you can compare.
How much do IPv4 addresses cost?
Leasing a /24 costs from €99 a month on a four-year term up to €139 month to month, excluding VAT. Buying costs from €19 per IP (October 2026), and larger blocks cost less per IP than a /24. A lease of a year or more has no setup fee, and nothing a lease includes costs extra. Our pricing page lists every rate, including lease to own.
How quickly can I start using the addresses?
A lease is usually live within 24 hours of payment. A purchase waits for the registry: we file the transfer within 24 hours of payment, and the RIPE NCC usually completes it in 1-3 business days. ARIN and APNIC transfers usually take 2-4 weeks. Registry processing is outside our control, and complete paperwork keeps it short.
Do I need my own ASN?
No. Your data center or upstream can usually announce the block from its own ASN, with a letter of authorization from us. Where no provider can announce it, we route the block to your server over a GRE or WireGuard tunnel, which needs no ASN at all. If you want an ASN of your own, we can act as its sponsoring LIR for €99 a year.
Are your IPv4 addresses clean?
Every block is checked against 10+ blacklists before handover, and leased blocks are monitored for as long as you have them. If a listing appears, we work through the delisting with you. After handover, reputation depends on the traffic sent from the addresses. Blacklists and other networks make their own decisions, so we make no promise about deliverability or routing.
Can I use leased IPv4 addresses at AWS, Azure or Google Cloud?
At AWS and Google Cloud, yes, and at most other clouds with bring your own IP (BYOIP), OVHcloud among them. Azure wants the block registered in your own name, and Oracle Cloud's list of accepted statuses leaves out ASSIGNED PA, the usual status of leased space, so check those two with us first. For space leased from us we do the registry side: the ROA for the provider's ASN, the record changes and, where a provider asks for one, the letter of authorization. Where a provider has no BYOIP, as at Hetzner Cloud, a tunnel delivers the space instead. Our BYOIP guides cover each provider step by step.
Do I keep the same block when I renew?
Yes, if you renew on time, and at no extra charge. Under our Block Continuity Guarantee we do not reclaim, reissue or renumber a block we lease to you, and our Terms put that in writing. IP addresses are our business, so we have no reason to take a block back. If we were ever required to withdraw one, by a registry for example, you would get at least 60 days' notice and an equivalent block at the same price.
What is included in a lease?
The registry and reputation work, in one monthly price: the RPKI ROA, the route object, rDNS, WHOIS updates to your organization, blacklist monitoring, abuse report forwarding, and a Letter of Authorization whenever you need one. On request, we correct geolocation with the major providers and give you a dedicated account manager. Technical support is included, and there is no premium tier.
Which block sizes and regions do you offer?
Blocks from a single /24, which is 256 addresses. We sell them in the RIPE NCC, ARIN and APNIC regions, and lease them from our own RIPE NCC address space. Most networks filter anything smaller than a /24, so for fewer addresses we route a smaller range to your server over a GRE or WireGuard tunnel. We have blocks from /24 up to /18 in stock, to buy or to lease. Leases are priced up to a /21 and quoted from a /20.
Can I sell my IPv4 addresses to you?
Yes. We buy blocks for our own inventory, in the RIPE NCC, ARIN and APNIC regions. Send us the block and its registry, and we will value it for free. A sale can complete in as little as one to two weeks from valuation, and the RIPE NCC's part usually takes 1-3 business days.
Buying IPv4
Where can I buy IPv4 addresses?
From organizations that hold space they no longer need. In practice that rarely happens directly. Most sellers work through a broker who finds the counterparty, verifies the block and handles the registry side. Open marketplaces exist too. What matters more than the venue is whether whoever you buy through can show you the block's history and stands behind the transfer. We sell from our own inventory, so you buy straight from the block's holder, without going to market alone.
How do I request IPv4 from a registry directly?
You open an account with the registry covering your region and meet its criteria. In practice this is no longer a route to meaningful quantities. The free pools are effectively gone and what remains is rationed or waitlisted, so almost all address space now changes hands on the transfer market. Tell us your region and we will say plainly whether a direct request is worth attempting or whether a transfer is the faster path.
Which registry regions can I buy in?
We handle purchases in the RIPE NCC, ARIN and APNIC regions, and inter-registry transfers between them where policy permits. We do not currently transact in the LACNIC or AFRINIC regions. Conditions differ by region: some require you to document need before approving a transfer, some require an account in good standing first, and the paperwork differs accordingly. We work out which applies to your case before anything is signed.
What should I check before buying a block?
Four things. Who has held it since it was assigned, and whether the seller is genuinely entitled to transfer it. Its current registry status. Whether it was announced by anyone without a claim to it while it sat dormant. And its blocklist history. We run all four as part of every sale, and you see the results before you commit rather than after.
Do I need a sponsoring LIR to buy in the RIPE NCC region?
It depends on what you buy. An allocation (PA) can only go to a RIPE NCC member, so you need an LIR account of your own. Independent space (PI) can be held through a sponsoring LIR instead, and we can be yours, so the purchase and the registry relationship sit with one party. Legacy space needs neither, though RPKI for it needs a contract.
Leasing IPv4
What happens at the end of a lease?
You can extend, resize, or hand the space back. Monthly leases can be canceled with 30 days notice, and fixed terms of a year or more run to the end of the agreed period. If you want to keep the block, you keep it: that is the Block Continuity Guarantee, and it is in our Terms of Service rather than sold as a premium tier. If you would rather end up owning it, lease to own makes the block yours over time, on terms agreed in writing before the lease starts. If you do end a lease, we ask that you stop announcing the block on the end date so it can be reissued.
Do you set up RPKI?
Yes. We create the ROA for your announcement as part of setup, so the route validates instead of being flagged invalid by the growing number of networks that enforce RPKI.
What is an LOA, and when do I need one?
A Letter of Authorization is the holder's written permission for a network to announce a block. Data centers and upstreams usually ask for one before they accept an announcement of space that is not registered to you. For any block you lease from us, we issue one whenever you need it.
What is an IRR object, and do I need one?
An Internet Routing Registry object is a public record stating which AS number is entitled to announce a given prefix. Carriers and large networks build their route filters from these records, so an announcement with no matching object is frequently dropped before it propagates. It exists to stop address space being announced by parties with no claim to it. For space you lease from us, we create and maintain the object, alongside the RPKI ROA, which serves the same purpose with cryptographic proof rather than a database entry. Space you buy is registered to you, so you set up both yourself, or your sponsoring LIR does; we can check that they are in place and valid.
Selling IPv4
What does it cost to sell to you?
The valuation is free. The price you receive and any fee are set out in the written agreement before anything moves, so you know the net amount before you sign.
What is my block worth?
It depends on size, registry region and how clean the space is. A /24 usually fetches more per address than a large block, because almost any buyer can take one. Legacy space usually carries a premium, and a history of blocklist entries pulls the figure down. We give a free valuation based on what comparable blocks are actually transacting at rather than a headline rate.
How long does a sale take?
Agreement, contract and paperwork usually run one to five business days on our side. Registry processing follows and is outside anyone's control: the RIPE NCC typically completes in 1-3 business days, while other regions take considerably longer.
When do I get paid?
Payment terms are set out in the agreement before it is signed, including when payment is due relative to the registry transfer. You will not be asked to give up control of the space before the agreed terms have been met.
Can I sell only part of a block?
Usually, provided it splits into prefixes that are still routable. A /24 is the practical floor, since most networks filter anything longer. Tell us what you hold and we will tell you how it can be divided and what each part is likely to fetch.
IPv6
Do I need IPv6 if my IPv4 works fine?
Not urgently, but it is cheaper to add now than to keep buying IPv4 as you grow. The usual trigger is either cost, since IPv4 per-address pricing starts to hurt at scale, or a reachability complaint from users on an IPv6-only mobile network.
What size should I take?
A /48 is the standard site allocation and is enough for most single deployments, since it still contains 65,536 /64 subnets. Take a /44 or /40 if you assign space downstream to customers or run many separate sites. If you are unsure, describe the deployment and we will suggest a size.
Can I announce it with my own ASN?
Yes. We issue a Letter of Authorization for the prefix and your upstream accepts the announcement, exactly as with IPv4. If you have no ASN, your provider can usually announce on theirs, or you can route it through one of our tunnels.
Does it work over a GRE or WireGuard tunnel?
Yes. We can deliver IPv6 over the same tunnel setup we use for IPv4, so a single endpoint can carry both. Worth mentioning up front so we configure it in one pass.
How is IPv6 priced against IPv4?
Far lower, because the scarcity that drives IPv4 pricing does not apply. We quote per allocation rather than per address. Tell us the size and duration and we will come back with a price.
GRE and WireGuard tunnels
What does a tunnel do to latency?
It adds the round trip to our nearest endpoint, so siting matters more than the protocol. Pick an endpoint close to your server and the overhead is typically small. We will tell you which endpoint suits your location before you commit.
Will it work behind NAT?
WireGuard handles NAT well. Plain GRE does not traverse NAT reliably, so if your endpoint has no public address of its own, WireGuard is the option to take.
What MTU should I use?
Lower than the standard 1500, to leave room for the encapsulation headers. We supply the exact value with your configuration along with MSS clamping, which is what prevents small packets working while large transfers hang. Both can be changed on request.
Can I run BGP over the tunnel?
Yes, if you have an ASN and want to manage the announcement yourself. Most customers do not need this and take the simpler static setup instead.
Can I tunnel space I bought elsewhere?
Yes. We can route address space you already hold, provided you can issue a Letter of Authorization showing you are entitled to announce it.
PI and ASN sponsorship
What does a sponsoring LIR actually do?
Independent resources such as PI space, legacy blocks and AS numbers have to be tied to an LIR that maintains the registry relationship. We hold that relationship for you. The resource stays assigned to your organization; we handle the agreement, the registry objects and the annual administration.
Do I lose control of my resources?
No. The assignment stays in your organization's name. Sponsorship is an administrative relationship, not a transfer of ownership, and you can move it to another LIR whenever you choose.
Can you take over sponsorship from another LIR?
Yes, and it is a routine change. We coordinate with your current sponsor and the registry so the resource is never left unsponsored. Tell us what you hold and we will confirm what is involved.
What is the setup fee for?
The one-off €149 covers onboarding a resource: verifying the assignment, drawing up the sponsorship agreement, and creating the registry objects and RPKI configuration. After that it is the annual fee for that resource and nothing else.
Do you sponsor legacy space?
Yes. Legacy blocks are a significant part of what we sponsor. Legacy resources sit under different registry conditions than ordinary PA space, so tell us what you hold and we will walk through exactly what applies to your block.
What exactly is LIR sponsorship at the RIPE NCC, and when do I need it?
In the RIPE NCC service region, provider independent resources cannot sit on their own; they have to be attached to a Local Internet Registry that maintains the registry relationship on the holder's behalf. That attachment is the sponsorship. You need one if you hold or are acquiring PI space, legacy blocks or an AS number and do not run your own LIR. It is common to arrange it at the same time as a purchase, so the transfer and the ongoing administration end up with one party rather than two.
Pricing and terms
Can I lease to own?
Yes. You start with a lease, and the block is yours after the last payment, one to five years later. You can also buy it out early by paying the remaining months in one go, with no penalty. Per /24 of address space, it costs from €550 a month over one year, €325 over two, €255 over three, €220 over four and €200 over five, excluding VAT. Those rates are for larger blocks; a single /24 costs more. Where VAT is charged, it is due upfront on the full contract amount. We put the terms in writing before you start.
Is there a setup fee?
On short leases and on sponsorship. A lease has a one-off setup fee of €199, which we waive when the total value of the contract is above €499: in practice on every lease of one year or more, and on month-to-month leases above €499 a month. Sponsorship has a one-off setup fee of €149 per resource. Lease to own has none.
Are there any other charges?
Not for the service itself: abuse handling, LOA, RPKI and the rest of what a lease includes cost nothing extra. One charge in our Terms is worth knowing: if an address stays on a major blocklist after the time allowed to resolve the listing, it costs €10 per listed address.
What payment methods do you accept?
We accept bank wire transfers, credit cards, and PayPal. Payment terms are set out in the agreement before you sign it.
Can I upgrade my block size?
Yes. You can upgrade to a larger block at any time. We will pro-rate the difference on your current billing cycle.
What is your cancellation policy?
Monthly leases can be canceled with 30 days notice. Fixed terms of a year or more run to the end of the agreed period, with three calendar months' notice before renewal. Buying, selling, sponsorship and monitoring each have their own terms, set out before you sign.
Do you offer volume terms?
Yes. Longer lease terms cost less per month, and orders of /20 and larger receive custom terms. Contact us for details.
Are IPv6 leases available?
Yes. We offer /48, /44, and /40 allocations. Contact us for larger allocations.
