Our Services

Our team specializes in buying and selling IPv4 space for our customers. Why would you want to buy, sell or rent IPv4 space? Below is a short list of the main reasons.

IPv4 for proxy services
/24 – /20 · buy or lease

IPv4 Proxy

Buy or lease clean IPv4 ranges for legal proxy services, with a reputation history you can check before the deal.

IPv4 for legal mailing
/24 – /22 · clean history

Legal Mailing

Blocks without blocklist history, suitable for legal mailing platforms and transactional email infrastructure.

IPv4 for infrastructure
/22 – /16 · purchase

Infrastructure

Address space for data centers, hosting and any growing network — from a single /24 up to /16 and larger.

Other IPv4 use cases
any size · ask us

Anything Else

Social media marketing projects, search engine tracking, retail price crawling, TLD domains and other legitimate use cases.

// sizing address space

How much address space do you need?

Pick a prefix length and see exactly what it buys you. Every step shorter doubles the block — the single fact that drives the whole IPv4 market.

Prefix length
Prefix /22
Addresses 1,024
/24 blocks 4
Netmask 255.255.252.0
Example range 198.51.100.0 – 198.51.103.255 Documentation prefix from RFC 5737 — illustrative only.
your block rest of the /16 Each cell is one /24. The whole grid is a single /16 — 256 × /24 = 65,536 addresses.
Common block sizes we buy and sell
Prefix Addresses /24 blocks Typically used for
/24 256 1 Smallest globally routable prefix — proxies, mail, a first block for a new ASN
/23 512 2 Growing proxy pools and small hosting platforms
/22 1,024 4 The common entry size for hosting providers and ISPs
/21 2,048 8 Multi-site hosting, CDN edge deployments
/20 4,096 16 Data center build-outs, regional ISPs
/19 8,192 32 Established ISPs, large managed-hosting estates
/18 16,384 64 Carrier and broadband access networks
/17 32,768 128 National operators, large cloud platforms
/16 65,536 256 Legacy holdings and the largest blocks that trade regularly

Need something larger than a /16, or several blocks in one region? Tell us what you're building and we will put a package together.

// how a transfer runs

From first call to routed prefix

An IPv4 transfer is a registry procedure, not just a purchase. These are the five stages every deal we broker goes through.

  1. 01

    Scope & valuation

    We agree the prefix size, the RIR region and any reputation requirements, then price the block against recent comparable trades.

    • size & region
    • indicative pricing
    • timeline
  2. 02

    Due diligence

    Before anyone signs, we check what the block has been doing: WHOIS and routing history, blocklist records, geolocation entries, and whether the holder is actually eligible to transfer it.

    • WHOIS history
    • BGP announcements
    • blocklist records
    • geolocation
  3. 03

    Contract & escrow

    Purchase agreement signed by both sides, funds placed with a neutral escrow agent and released only once the registry change is confirmed.

    • purchase agreement
    • neutral escrow
    • release on confirmation
  4. 04

    Registry transfer

    We file and track the transfer with the relevant RIR — ARIN specified-recipient and inter-RIR transfers, or the equivalent RIPE NCC, APNIC, LACNIC and AFRINIC procedures — including any needed-use justification and holding-period checks.

    • ARIN 8.2 / 8.3 / 8.4
    • inter-RIR
    • holding periods
  5. 05

    Routing handover

    The part most brokers leave to you. We hand over a block that is ready to announce: authorization letter, RPKI route origin authorisations, IRR objects and a clean geofeed.

    • LOA
    • RPKI ROA
    • IRR objects
    • geofeed
// straight answers

What buyers and sellers ask us first

The questions that come up on almost every call. If yours is not here, just write to us.

How long does an IPv4 transfer take?

Usually two to six weeks. Due diligence and contracting are quick; the variable is how fast both parties produce registry documentation and how busy the RIR queue is. Inter-RIR transfers take longer than transfers inside one region because two registries have to agree.

Do I have to justify the addresses I am buying?

It depends on the registry. ARIN requires a recipient to demonstrate need for specified-recipient and inter-RIR transfers. RIPE NCC does not ask for needs justification on transfers of existing allocations inside its region. We tell you which rules apply before you commit to anything.

What is the smallest block worth buying?

A /24, or 256 addresses. Most networks on the internet filter prefixes longer than a /24, so anything smaller cannot be announced globally on its own — it can only be used inside someone else's larger announcement.

Can I lease address space instead of buying it?

Yes. Leasing gets you routable space in days rather than weeks, with an authorization letter and route objects from the holder, and no registry transfer. It suits short projects and testing. Buying is the better economics if you need the space for years.

How do you check whether a block is clean?

We pull the block's WHOIS history, look at how and by whom it has been announced in BGP, check it against the major blocklists, and review its geolocation records. You see the findings before signing, not after.

I am selling — how do I know I will get paid?

Funds sit with a neutral escrow agent from the moment the agreement is signed. The buyer cannot withdraw them and you are paid as soon as the registry confirms the transfer. You never have to hand over the block on trust.
