We come back with pricing and terms for the block we have found. This usually takes 1-3 business hours.
- Hour 4
Contract
Once agreed, we draw up the purchase agreement between you and the seller and send it out for signing. Compliance and chain-of-custody checks on the block happen here.

Transfer filed with RIPE
We handle the transfer paperwork and registry updates on your behalf, submitting within several hours after payment usually. RIPE takes 1-3 business days under normal conditions, after which the addresses are registered to your organisation.
Indicative timings for straightforward requests, not a guarantee. Larger blocks, incomplete documentation or registry processing can take longer.
PA and legacy blocks in stock
We hold and broker both provider aggregatable space and legacy blocks, and we handle sales into the RIPE, ARIN and APNIC regions.
PA space
Ordinary allocated space from LIR holdings. The straightforward case: a clean transfer under standard registry policy, available in most sizes.
Legacy blocks
Pre-RIR assignments that sit under different registry conditions and carry fewer ongoing obligations. Often the more attractive asset, and a meaningful part of our inventory.
| RIR | Region | Transfer Time |
|---|---|---|
| RIPE NCC | Europe, Middle East, Central Asia | Usually 1-3 business days |
| ARIN | North America, Caribbean | 2-4 weeks |
| APNIC | Asia Pacific | 2-4 weeks |
We sell into RIPE, ARIN and APNIC. Inter-RIR transfers between those three are handled where policy allows.

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.

Buying questions
Where can I buy IPv4 addresses?
From organisations 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 hold inventory ourselves and broker from a network of sellers, so most requests can be matched without you 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 into RIPE, ARIN and APNIC, 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 brokering, and you see the results before you commit rather than after.
Do I need a sponsoring LIR to buy in the RIPE region?
If you are not a Local Internet Registry yourself, the resource has to be tied to one. We can act as your sponsoring LIR, which means the purchase and the ongoing registry relationship sit with the same party instead of you arranging them separately.
