Sell your unused IPv4 space

Your idle IPv4 addresses are a valuable asset. We buy them for our own inventory, with a free valuation, the price and terms agreed in writing, and the entire transfer handled securely.

Why now

Why sell now?

IPv4 demand continues to outstrip supply. The secondary market remains strong.

  • Strong demand

    IPv4 demand continues to outstrip supply. Your unused addresses are a valuable asset.

  • We buy it ourselves

    We buy for our own inventory, in the RIPE NCC, ARIN and APNIC regions, so there is no buyer to find and no one in between.

  • Secure transactions

    Terms, payment and the transfer steps are agreed in writing before anything moves, so both sides know exactly where they stand.

  • Fast process

    From valuation to completed sale in as little as one to two weeks. The RIPE NCC's part usually takes 1-3 business days.

How it works

How the sale process works

  1. 01

    Free valuation

    We assess your block size, RIR, reputation, and routing history to determine fair market value.

  2. 02

    Our offer

    We make you an offer for the block ourselves, based on that valuation.

  3. 03

    Agreement

    The price, the payment terms and the transfer steps go into a written purchase agreement before anything moves.

  4. 04

    Transfer & payment

    We prepare the registry's transfer documents for you to sign and keep you updated as the transfer progresses. Payment follows the terms set out in the agreement.

Valuation

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: the RIPE NCC applies 24 months, ARIN 12. And the registered holder has to match the company that signs. Both are worth checking on day one.

We buy for our own inventory, so the answer is an offer from us, not 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

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.
🇳🇱Dmitry OkulovPublished with the customer's permission -
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!
🇫🇷QuentinPublished with the customer's permission -
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.
🇩🇪Markus WolfPublished with the customer's permission -
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.

FAQ

Selling questions

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.
