  4. Why do you think the world is running out of IPv4 addresses? Because it is popular and there are many computers and cellphones, tablets all connected to a IP address.
  5. How long do you think it will take before the IPv4 addresses are completely exhausted? I believe they have ran out already. Everything I read said that it should of ran out by 2012.
  6. Since IPv6 is the long-term solution for this issue, why do you think we are still using the assigning IPv4 addresses on the internet? I think because it is trying to utilize the IP of IPv4 before they move on to IPv6 which has a lot of IP address spaces.
  7. Do you think the possibility exists for some companies to hoard IP addresses and not release them back to ARIN to turn a profit? I think they might hold out for a profit. IP address is limited and people know they are running out so yes this seems logical.
