Fast Process
From valuation to completed sale in as little as one to two weeks. The RIPE side itself usually takes 1-3 business days.
How the Sale Process Works
Free Valuation
We assess your block size, RIR, reputation, and routing history to determine fair market value.
Buyer Matching
We find qualified, verified buyers from our global network who match your block specifications.
Negotiation
We negotiate on your behalf to get the best possible terms for your IP space.
Transfer & Payment
We handle all RIR transfer paperwork and keep you updated as it progresses. Payment follows the terms set out in the agreement.
Before you sell
There is no single price per address. Size, region, reputation, registration type, paperwork and routing history all move it, so we value each block on its own.
Two things stop a sale outright. Space received through a transfer usually cannot move on straight away: RIPE applies 24 months, ARIN 12. And the registered holder has to match the company that signs. Both are worth checking on day one.
We also buy for our own inventory, so sometimes the answer is an offer from us rather than a search for a buyer.
What to have ready
- The prefix or prefixes, exactly as registered
- The registry they sit under
- The registered holder, and whether it still matches your company
- Whether the space is announced now, and from which ASN
- When you acquired it, if it came by transfer
- Whether to sell all of it or split it

A few 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.
I’ve been working with RTM Networks and Rick for several years, and our cooperation has been a very positive experience. Interestingly, our relationship started with RTM as our customer. We sold several /24 IPv4 prefixes to them, and I was impressed by how professionally the transactions were handled. Rick and his team managed the entire process clearly and responsibly, making each deal straightforward and easy from our side. Some time later, the roles were reversed and we became their customer, leasing a /24 IPv4 prefix from RTM. For our business, this turned out to be a practical and economically efficient solution. What I particularly appreciate is the combination of professionalism and a personal approach. Communication with Rick has always been direct, friendly and reliable, and it’s good to work with people who understand the industry and take responsibility for getting things done. Based on our experience on both sides of the relationship, I can confidently recommend RTM Networks.
I have been an RTM customer for about a year now (starting with a sister company, Bakker IT), and I have never encountered any hiccups. Based on my experience, Rick is truly dedicated to providing an excellent customer experience, at honest prices with great customer support and reactivity. They are my LIR as well as my lease-to-own sponsor for IPv4 space. The addresses are super clean! They truly are looking for long-term customership, and everything is there for it. You can't go wrong with RTM Networks!
I've known Rick since 2014, and over the past 12 years he has helped me tremendously in many different ways. When it comes to RIPE, networking, and everything related to network infrastructure, Rick is someone I know I can always rely on. His knowledge and experience are excellent, but what I appreciate most is his reliability. In all those years, he has never once let me down. Rick is incredibly helpful, friendly, trustworthy, and always willing to think along or help when needed. After 12 years of working together, I can confidently say that Rick and RTM Networks are people you can truly depend on. Rick, thank you for everything you've done over the years. I genuinely appreciate our cooperation and hope we'll continue working together for many more years!

Thinking of selling IPv4 space?
Send us the block and its registry and we will assess what it is worth on the current market. We usually reply in 1-3 business hours.
Selling questions
Is selling IPv4 addresses actually allowed?
Yes. Every registry has a transfer policy that lets a registered holder pass the rights to another party, provided both sides meet the conditions and the documentation holds up. What changes hands is the registration and the right to use the space, recorded through the registry rather than agreed privately between two parties, which is precisely what makes it enforceable.
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: RIPE 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.
