IPv4 Address Exhaustion
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 1 - Assumptions
Method 1 - Assumptions (contnd)
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 Address Demand for Cellular IP plus DSL + cable modem ( /8s)
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 (using 80%, 50% and 30% increase per year)
3 assumed rates of growth (global)
Global factor of increase 1.8 per annum (year after year)
Global factor of increase 1.5 per annum (year after year)
Global factor of increase 1.3 per annum (year after year)
Global Total - Method 2 (1.8, 1.5, 1.3)
Method 2 - summary of exhaustion dates (4.83 x /8s consumed in year 2000)
Method 3 global projections on various rates of allocation of IPv4 address space from RIRs to LIRs (using 16, 12 and 8 x /8s p.a.)
Global Total - Method 3 (16, 12 and 8 /8s p.a.)
Method 3 - summary of exhaustion dates
