If IPv4.Global’s mix of auctions, buy-now listings, and brokerage doesn’t fit your buying process, these five alternatives offer different paths.
My top pick is IPv4 Connect for fixed-price purchases. The important choice is whether you need ownership, private negotiations, or rented addresses, not simply the lowest advertised price.
Key Takeaways
- IPv4 Connect is my top pick: fixed prices, pre-payment blacklist reports, and managed transfers.
- Prefix Broker suits buyers comparing public listings who are comfortable paying in EUR.
- Addrex fits private transactions where counterparty vetting and standardized documents matter.
- IPTrading suits complex transfers needing registry-policy guidance rather than a shopping cart.
- IPXO offers leasing when access matters more than ownership.
How I tested
This comparison is a desk review, not a hands-on transfer test. I separated fixed-price sales, private deals, brokerage, and leasing before assessing price clarity, regional internet registry (RIR) coverage, blacklist checks, and routing authorization tools.
I also considered escrow options, ARIN Qualified Facilitator status, and how providers explain registry-dependent timelines.
Published asking prices are useful, but buyers still need to confirm currency, registry fees, and current availability before committing.
IPv4 Connect
IPv4 Connect pros
- Fixed-price Buy Now listings without an auction cycle
- Free pre-payment report checking each subnet against 100+ blacklists
- Reserve-first process for reviewing documentation before payment
- Managed transfers and pre-approval help for ARIN, RIPE, and APNIC
- Payment by secure wire or escrow
- Help clearing stale route and DNS records after closing
- Operated by Brander Group, an ARIN Qualified Facilitator
IPv4 Connect cons
- No auction bidding below the listed price
- Transfer timing depends on buyer readiness and registry review
- Some prefixes remain masked until NDA or reservation
My experience with IPv4 Connect
In practice, IPv4 Connect‘s fixed-price listings and reserve-first sequence are the strongest part of this offering for me.
I like seeing a fixed asking price, reviewing the blacklist report, and then deciding whether to pay through escrow. That removes auction uncertainty without asking me to skip diligence.
Managed transfer support and help clearing old route and DNS records also make the process appealing. A blacklist report is a screening tool, not a deliverability guarantee, and transfer approval and timing remain registry-dependent.

IPv4 Connect pricing
Prices are fixed per listing, with payment by wire or escrow. I value knowing the asking price before starting due diligence, especially with transfer support included in the offering.
Confirm the total in writing, since registry transfer fees may apply separately.
Prefix Broker
Prefix Broker pros
- Public fixed-price listings in EUR per address
- Multiple block sizes, including legacy space
- Clear currency and transfer-fee disclosures
- Broker holds funds until transfer completion
- Cross-RIR transfers supported
Prefix Broker cons
- EUR pricing creates exchange-rate exposure for US buyers
- Public inventory leans toward RIPE
- Legacy blocks can involve additional policy considerations
My experience with Prefix Broker
The offers grid makes it straightforward to compare asking prices across block sizes. I find that useful for budgeting, even before choosing a provider.
The purchase flow avoids auction bidding, but buyers paying from a USD account still need to account for currency changes between reservation and payment.
Prefix Broker pricing
Listings are denominated in EUR. Confirm the current asking price and any registry fees before paying; treat displayed USD equivalents as indicative only, not a locked exchange rate.
Addrex
Addrex pros
- Private marketplace with pre-qualified buyers and sellers
- Seller rights checked before listing
- Standardized legal documents and vetted agreements
- Counterparty anonymity until closing
- ARIN Qualified Facilitator
Addrex cons
- Inventory and pricing require registration
- More enterprise-oriented than self-serve
My experience with Addrex
Addrex’s private model makes sense to me for larger or sensitive purchases.
Counterparty vetting and standardized documents give procurement teams a defined process to evaluate. The trade-off is visibility: without joining, I can’t compare available inventory and prices as readily as on a public listing grid.
Addrex pricing
Request deal-specific pricing, including fees and escrow arrangements. Confirm access requirements and the full transaction cost before entering a negotiation.
IPTrading
IPTrading pros
- Works across ARIN, APNIC, RIPE, and LACNIC
- ARIN Qualified Facilitator
- Blacklist screening across dozens of lists
- Registry-specific guidance on estimated transfer durations
IPTrading cons
- No public price grid
- Timing varies with buyer readiness and registry review
- Brokerage rather than click-to-buy purchasing
My experience with IPTrading
I would consider IPTrading for legacy space, inter-RIR moves, or transfers connected to acquisitions.
Its policy-focused approach fits those conversations. Expect a broker-led process rather than browsing inventory and checking out, with registry review still affecting timing.
IPTrading pricing
Pricing follows a commission-based brokerage model. Request a written quote covering the broker’s fees and any separate transaction costs before proceeding.
IPXO
IPXO pros
- Self-serve IPv4 leasing and address management
- Automation for routing authorizations and reverse DNS
- Reputation monitoring
- Management of addresses from all five RIRs
IPXO cons
- Leasing does not provide ownership
- Promotional availability and regions may vary
- Subscriptions and token usage can add platform costs
My experience with IPXO
IPXO interests me when renting addresses makes more sense than buying them.
Its authorization and reverse-DNS automation address ongoing administrative work. That matters if leased ranges end up powering proxy setups, where address reputation shapes how traffic is treated.
It isn’t a substitute for a purchase when ownership is a firzm requirement.
IPXO pricing
Check current lease rates, billing commitments, and platform charges together. Don’t budget around an older campaign without confirming eligibility, term length, and any usage-based costs.
Conclusion
IPv4 Connect is my top pick for fixed-price IPv4 purchases. Its reserve-first process, pre-payment blacklist report, escrow option, and managed transfer support offer a practical route to ownership without auction bidding.
Prefix Broker is a runner-up for comparing EUR-priced listings. Addrex fits private enterprise deals, IPTrading suits policy-heavy transfers, and IPXO serves buyers who prefer leasing.
Before committing, confirm current availability, the complete cost, and your registry’s requirements. Use reputation reports as one part of due diligence, and treat transfer estimates as registry-dependent rather than guaranteed.
