Conclusions
does not include the possibility of reclaiming unused addresses
NATs not included - proxy servers are included where indicated
new services and applications - additional IP addresses are only needed for additional infrastructure nodes and additional terminals/computers (not necessarily for new applications per se)
2 very different methods used
- method 1 based on projections for terminals and lines (not addresses)
- method 2 based on projected registered IP address allocation only
method 1 best case - very difficult to extrapolate
close agreement between both methods in most likely case & 1.5
close agreement between both methods in worst case & /1.8
we favour most likely case / 1.5 global increase yearly
