Services
IP address services
IPv4 to lease, buy or sell, IPv6 allocations, LIR sponsorship, tunnels and blocklist monitoring: the services an organization needs to obtain, hold and operate its own IP address space.
Buy IPv4
Purchase IPv4 address blocks outright with full ownership transfer. Every size from /24 to /18 is in stock, and we handle all RIR paperwork.
IPv4 leasing
Lease IPv4 addresses month to month or for longer terms, from a /24 to a /18. You keep the same block on renewal under our Block Continuity Guarantee.
Lease to own
Start with a lease and own the block after one to five years. We put the terms in writing before you start.
PI & ASN sponsorship
Hold PI space, legacy blocks or an AS number without running your own LIR. We act as sponsoring LIR and handle the registry side.
Sell IPv4
Turn your unused IPv4 space into capital. We buy it ourselves, for our own inventory, and handle the transfer.
GRE tunneling
GRE or WireGuard tunnels that route leased or owned IPv4 space through your own infrastructure, with full BGP support.
Blacklist monitoring
Continuous RBL list checking and abuse mailbox management. We monitor your IPs across major blocklists and can forward abuse reports to specific clients.
Lease IPv6
IPv6 allocations from a /48 upward, alongside your IPv4 or on their own. Usually the cheaper way to grow.
How it works
Get started in three simple steps
01
Contact us
Tell us what you need: subnet size, region, intended use. We usually respond in 1-3 business hours with a tailored offer.
02
Review & agree
Review your custom quote, sign the agreement, and complete payment. We prepare the registry paperwork, and for a lease we set up the ROA and, whenever you need one, the Letter of Authorization.
03
Go live
Once payment is confirmed, leases are usually live within 24 hours. Reverse DNS and RPKI included, geolocation corrections on request. Purchases follow the registry transfer.

Testimonials
Trusted by network operators across Europe
In the words of the businesses we have handled transfers, leases and sponsorships for.
We successfully worked with RTM Networks to buy a legacy IPv4/24 and receive a PI IPv6 /48. RTM is our LIR Sponsor and and the whole process was really smooth. Everything worked out the easy way without any troubles in transfer of the IP Ranges. We continue to work with them as LIR sponsor and infrastructure for one of the backbones we are connected now. Special thanks Rick for helping us in setting up the mesh connected backbones and bird. After decades in the business a great experience with cool people. Thank you for doing a great job.
For me, what sets RTM Networks apart is the people. Rick combines professionalism with a genuinely personal approach: he is direct, friendly and someone you can rely on, and he and his team understand this industry and take responsibility for getting things done. Working with them over several years has been a very positive experience, and we have seen it from both sides. Our relationship actually began with RTM buying from us: we sold them several /24 IPv4 prefixes, and every deal was handled so professionally, clearly and responsibly that it was easy for us. Later the tables turned and we leased a /24 from them, a practical and economical solution for our business. Seller first, customer later: either way, I recommend RTM Networks with confidence.
In twelve years of working with Rick, he has never once let me down. Since 2014 he has helped me enormously, in many different ways, and he has always been incredibly helpful, friendly and trustworthy, ready to think along or lend a hand whenever I needed it. When it comes to RIPE, networking or anything else in network infrastructure, his knowledge and experience are excellent, but it is his reliability I value most: he is the one I know I can always count on. Rick and RTM Networks are people you can truly depend on. Rick, thank you for everything over the years. I really appreciate our cooperation and hope we will keep working together for many more.
In about a year as a customer of RTM, starting out through their sister company Bakker IT, I have not run into a single hiccup. Rick is truly dedicated to giving his customers an excellent experience, and you can tell they are after a long-term relationship, with everything in place to make it one. RTM is both my LIR and my lease-to-own sponsor for IPv4 space. Prices are honest, support is great and quick to react, and the addresses are spotless. You can't go wrong with RTM Networks!
Thanks to Rick, our entire network segment was transferred without a single issue. He is a great help with anything to do with RIPE, whether registrations, transfers or routing. We started doing business with RTM Networks over a year ago, when we leased an IPv4 network from them.
I never had to wait two days or more for a reply to a single email. So far I have only dealt with Rick, who answers fast and has been very helpful. Good people, reasonable prices, and everything works. I buy from Austria.
About
Three things we hold ourselves to
The reasons customers come back, and what we measure ourselves against.
- Speed
Fast to answer, fast to set up
A quote usually back in 1-3 business hours, and leased space live within 24 hours of payment. Nothing sits in a queue waiting for someone to notice it.
- Service
No nonsense, and we go the extra mile
A team that answers you directly, with no handoffs and no ticket queues. We work across the RIPE NCC, ARIN and APNIC regions and know the transfer policies, the market and the network side well enough to tell you what actually applies to your case. If your requirement does not fit a standard package, we build around it.
- Security
Everything on paper before anything moves
A written contract that sets out exactly what you are getting, before anything moves. Payment terms and the transfer sequence are agreed up front. For leased space, the ROA is set up as standard, with a Letter of Authorization whenever you need one. No hidden fees, no surprise charges, and honest market advice.
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.
