Tixx by Prefixx:
every box ticked.
Tixx is the name of our quality control checklist. It consists of six checks, and every block that we broker has to pass all of them before any money changes hands. Some of the checks are quick, others can take a week or more, but none of them are ever skipped.
A dedicated account manager, start to finish.
Every Prefixx engagement begins with a dedicated account manager. That person stays with you from the initial consultation all the way through to the final transfer, and does not disappear halfway. The team behind them is multilingual and has hands-on experience with transfers at all five of the Regional Internet Registries, which means that at every step along the way there is somebody available who has done this before.
We work on a no-cure, no-pay basis. If we do not deliver results, you simply do not pay, and that has been the arrangement since the beginning. Every client also receives a complimentary introductory consult, in which we assess the situation and map out a sensible path forward. The number of active clients is kept deliberately low. In this business a single missed detail can be the difference between a deal that closes and a deal that quietly falls apart, and details tend to get missed when a team takes on too much at once.

Carefully vetted, fully transparent.
All partners and resources that are offered through the Prefixx platform go through a careful vetting during onboarding. We vet the seller first. The block itself is then vetted separately, and there is a good reason for doing it in two rounds: even a perfectly legitimate seller can be holding space with problems that they were never aware of.
Whatever we find ends up in a health report that both the buyer and the seller can read, so neither party has to take anything on faith. If you would like to know more about our process, or about how Prefixx can help your company with IPv4 procurement and divestment, you are welcome to schedule a free consult.

Transfer readiness, scored.
Before any transaction moves forward, our pre-sale audit takes a long look at the transfer readiness of the block in question. Are the registry accounts in good standing? Are there conflicting claims, or outstanding obligations attached to the space? Have all of the RIR-specific transfer requirements been met? Each of those questions has to be answered before we allow a deal to proceed.
The audit produces a transfer readiness score, together with a summary of the checks that passed, the checks that failed, and the checks that deserve a closer look. Issues are flagged and resolved by our team before the transaction proceeds. Fixing a problem afterwards is always more expensive than fixing it beforehand, so we prefer not to work that way.

Tixx by Prefixx.
The six quality control checks below are applied to every block and every transaction that passes through our hands, without exception.
Ownership validation
The first thing that we verify, against the registry records themselves, is that the resources are being sold through legitimate channels, and that the identity of the owner has been properly confirmed.
Transfer eligibility
Next comes eligibility. We confirm that the resources may actually be transferred under the applicable registry policies, and that there is nothing standing in the way of the move.
Blacklist reporting
Prefixx produces blocklist reports during the onboarding, and then once more shortly before the completion of the transfer, so that the block arrives with a clean bill of health.
Routing records and visibility
We also check that the space is no longer in active use anywhere, and that any BGP announcements, assignments and records that remain from the previous holder have been taken down.
Secure funds transfer
Funds that have been deposited into escrow are only released to the seller once the transfer of the resources has been completed and confirmed by the registry. Not a day earlier.
Policy compliant
Finally, we check that every requirement set by the local RIR has been met, and that the registry accounts on both sides are up to date and in good standing.
Frequently asked questions
Tixx by Prefixx is the quality control system that we apply to every transaction. It covers IP reputation analysis, blocklist screening, WHOIS record verification and compliance checks, and its purpose is a simple one: the address space that changes hands must be clean and transferable.
We start with the ownership records, since nothing else matters if those are wrong. After that come the abuse reports and blocklistings, the routing history, and the question of whether any conflicting claims or liens exist against the space. Last of all we make sure that the block meets the transfer requirements of the RIR in question.
It affects it a great deal, and rather more than most people expect. Blocks with a history of spam, abuse or blocklisting can be difficult to use effectively, and a poor reputation often leads to email deliverability problems and to content filtering. For that reason Prefixx screens every block through our reputation management system before any transaction takes place.
Yes, we do. As part of the Tixx process we generate a detailed reputation report for every IPv4 block that is involved in a transaction. The report covers blocklist status, abuse history, routing information and the accuracy of the geo-location data, and both parties receive a copy of it.
If the Tixx process identifies issues, we work to resolve them before anything proceeds. That may mean delisting from blocklists, correcting WHOIS records, or updating geo-location data, depending on what was found. And if a block simply cannot be brought clean at a reasonable effort, we will tell you so honestly, and the deal does not go ahead on that block.
