Beware of dealing with Marcus Mamolen or someone calling themselves Ryan Knox.
If you have an IP address block you’re not using, beware of a company called IPV4 Depot. Their website is at http://www.ipv4depot.com.
I had a class “C” (199.33.253.0/24) IP address block and was approached by one Ryan Knox of IPV4 Depot. I decided I wasn’t using it and that it should go to someone that needed it. Ryan, in an email, told me it was worth at least $3500 or $14 to $16 per IP address. Long story short, I trusted them. BIG MISTAKE!
The problem is that you’re not talking about a deal that will net you enough money to contract with a lawyer to hammer out the details in an extensive contract. That’s what these scammers are counting on.
IPV4 Depot is registered with the ARIN as a transfer agent but there doesn’t seem to be any obligation on the part of a transfer agent to be ethical or honest.
Whatever you do, don’t work with IPV4 Depot as you will spend a lot of time and effort watching your back from these unscrupulous people.
