IPv4 Address Exhaustion Paul Mylotte & Tony Holmes paul.mylotte@bt.com tony.ar.holmes@bt.com
Agenda
How much does IANA/ICANN still hold?
Available for allocation to RIRs
Special Purpose IPv4 Address Space
IPv4 Address Space currently allocated to the RIRs
Key Drivers for IP address space
But how many extra addresses are needed for future drivers?
Method 1 global projections on Cellular IP (mobile) + ADSL/cable modem demand
Method and Assumptions (1)
Method and Assumptions (2)
Global: Cellular IP (millions) (address demand - based on terminal demand)
Global: DSL+ Cable Modems (millions) (address demand - based on line demand)
Global Address Demand for Cellular IP plus DSL + cable modem (millions)
Global Total - Method 1
Method 1 - summary of exhaustion dates
Method 2 global projections on various rates of allocation of IPv4 address space from RIRs to LIRs
3 assumed rates of growth (global)
Global factor of increase 1.3 per annum (year after year)
Global factor of increase 1.5 per annum (year after year)
Global factor of increase 1.8 per annum (year after year)
Global Total - Method 2
Method 2 - summary of exhaustion dates
Comparison of projected dates
