About
About RTM Networks
Your European provider of IP space: a neutral IPv4 specialist from Amsterdam. IP services are all we do.
Company
Who we are
One provider for the whole of your IP space: IPv4 to lease, buy or sell, IPv6 to lease, and everything that comes with it.
RTM Networks leases, buys and sells IPv4 address space in every block size from a /24 to a /18, leases IPv6, routes address space over GRE and WireGuard tunnels, acts as sponsoring LIR for PI space and AS numbers, and monitors the reputation of every block it hands over. We lease from our own RIPE NCC address space, and buy and sell across the RIPE NCC, ARIN and APNIC regions.
We are not a hosting company and not a broker. IP services are our core business, so we have no interest in taking address space back. Under our Block Continuity Guarantee we do not reclaim, reissue or renumber a block you lease, and it stays the same block when you renew. You can build on a foundation that will not disappear from under you.
We do not sell you something just because you ask for it. We look at your plan with you and work out how we can best support it. And if another provider suits your situation better, we will happily point you to them. A satisfied customer is worth more to us than a quick sale.

FAQ
Frequently asked questions
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.

Leasing or buying IPv4: how the numbers actually compare
Lease or buy is usually framed as capital against cost. What decides it is the block: PA needs LIR membership, and PI cannot go to your customers.
