IPv4 Market Group has assembled a list of Questions and their Answers based on items asked of us by our clients.
Q: What is the status of inter-RIR transfers to or from the RIPE region?
A: The RIPE NCC policy 2014-05 “Inter-RIR Transfers”, authored by IPv4 Market Group president Sandra Brown, has been implemented. The RIPE NCC inter-RIR policy requires needs justification, which is a re-introduced concept for the RIPE region in order to be compatible with ARIN. Needs justification is based on 50% utilization over five (5) years. APNIC does not require needs justification.
Q: What does it mean on an ARIN registry record when it says “ADDRESSES WITHIN THIS BLOCK ARE NON-PORTABLE.”
A: This is listed in Public Comments, mostly on older registrations where an org used to be able to put this comment in their template, resulting in it showing up as a public comment in Whois. It just means that the ISP customer cannot take the IP addresses to another ISP. It does not impede a transfer.

Q: How should I submit a needs justification for an 8.3 transfer?
A: First, we recommend that you not be listed on the 8.3 transfer site, as you could be swamped with undesired transfer requests. Working with IPv4 Market Group will give you the most professional and competitive pricing experience you can find.
The instructions from ARIN are at: https://www.arin.net/resources/request/transfers_8_3.html
When you follow this process, we recommend your request not to be listed on the ARIN 8.3 STLS listing as a buyer.
In terms of providing information to ARIN, it seems to work to:
a) Show at least 80% use of each of your current allocations.
b) State at a high level how you will use the IPs – what locations, what purpose and so on. It is effective to show a growth chart such as the following
7000/8192 = 85% … Therefore request a /18
c) Substantiate the request with network layout diagrams, equipment receipts, customer lists or planned customer acquisition lists, and growth plans.
Q: Is it possible to purchase IPs in the ARIN region without performing needs justification?
A: ARIN enforces needs justifications on all IPv4 transfers. Therefore the only way to avoid needs justification is to acquire IPs without going through ARIN. This requires the acquisition of a company. If a company has signed an RSA or LRSA with ARIN, it is contractually obligated to inform ARIN of the sale. Otherwise ARIN has a right to reclaim the IPs upon realizing that the sale has been made.
Thus, the only type of IPs that can be acquired within a company, are legacy IPs. There are some small companies available with legacy IPs which can be purchased for only their IPs.
Q: If I wish to transfer IPs in the RIPE region, what are the guidelines in terms of block size?
A: RIPE NCC currently has a minimum transfer size of /22, but is considering the passage of a new policy to have no size limitation.
Q: Is it better for a company in the APNIC region to acquire IPv4 numbers from the ARIN region or from the APNIC region?
A: The advantage of acquiring IPs from within the APNIC region is that the transfer process is much more streamlined and more assured. The process itself is accomplished using MyAPNIC, and with only APNIC involved, is very quick. When ARIN is involved, there is the risk that the seller may have to prove ownership, if ownership has not previously been proven. ARIN adds at least 10 days to the process, to get through its queue, to collect the seller fee and affidavit of right to transfer, and to handover to APNIC. APNIC IPs are in relatively short supply.
Conversely, ARIN IPs can be slightly less expensive, and there is a much larger supply in the ARIN region, and thus whenever supply exceeds demand, there is the opportunity for better pricing.
Q: How long will IPv4 be around and in demand?
A: Who really knows? IPv6 uptake statistics are growing, but IPv4 is needed for dual stack, and IPv6 is much less prevalent than desired. Many predictions expect IPv4 to be in demand for the next seven to ten years.
Q: In purchasing IPs, how should IP quality be checked?
A: IPv4 Market Group is not an expert in this area, and we recommend that you seek engineering expertise. However, many of our customers use senderbase.org to assess IP reputation. If IPs are to be used for email, then many buyers will pre-test IPs to ensure they are not blocked by major email sites.
