"As a former owner of a /16 IPv4 block of internet (IP) addresses (block 143.170.0.0/16 formerly known as ISDN), these are the reasons I unreservedly recommend Sandra Brown of IPv4 Market Group as a superb broker for IPv4 address blocks:
Impeccable integrity and honesty: I did not need to rely on my normal legal counsel throughout a complex transaction, because Ms. Brown's firm acted as a fiduciary would.
Deep Technical Competence of the IPv4 address space and the status of the ISDN block, which resulted in promptly clearing the title to it.
High respect & access to the IPv4 community & ARIN which resulted in a smooth transfer of title from a previously owned but dissolved corporation to myself.
Complete Support: Ms. Brown's firm provided me with access to escrow services, and both an assets purchase sale & escrow agreements which I barely modified. All I had to do was sign & scan them.
If you have legacy IPv4 addresses you can not do better than relying on Ms. Brown's firm."

"Sandra,
Thank you two for all of your help. The space was transferred completely to us as of this morning. It was a pleasure working with you two. The process was easy and painless. If we ever need more space I will contact you again."

"Sandra, I can confirm that the transfer is complete and the payment has been performed. Thank you very much for your services.
As usual, we are very pleased with your services and it has been great to work with you again. IPv4 Market Group assisted me in the sale of our /16. We were under tight time constraints and we worked together to achieve a successful transfer to an ARIN based buyer on schedule.
I found IPv4 Market Group thorough, open and knowledgeable, and more importantly very prompt in managing the whole process to culminate the deal to my satisfaction. No doubt that IPv4 Market Group will give the best guidance to a seller even when it isn't in their own financial interest."
