Hi,
I want to add my observations to one of the points Desi raised in his email.

*/Why would India has only 0.27 IP address per Internet User, and not

countries, while the user base grew only by 205%, developing countries
and least develop countries didn’t participate in the race. IN
developing countries & LDCs the IP address space growth is less than the
growth of Internet users. Does that mean TATAs and SIFY’s are not
interested in having a public IP and interested in NAT?/*
From my perspective (having now spent 12 months working in India) there
is a lower subscriber:IP ratio, because the average session duration is
much shorter. In my experience the typical BRAS loading ratio is only
about 40% of provisioned subscribers.
In Australia, people typically leave broadband sessions up 24x7 which
results in 1 IP address being consumed per subscriber for the fixed
broadband session, and additional IPs are consumed for other sessions
(e.g. work PC; mobile phone; data card; whatever). If I look at myself
as a typical user I have an always-on work Internet connection; a
personal always-on Internet connection; and a couple of mobile devices
-- all consuming IP addresses.
I'm sure as the Indian market grows in broadband consumption, and
becomes more of an always-on service that the consumption of IP
resources will rapidly increase and start to reflect the sort of ratios
seen in Australia.
I'm sure that NAT is heavily used in India, although I am personally yet
to encounter it on any commodity services.
I would be very interested to hear from operators who say that NAT is
cheaper to deploy than it is to obtain additional IP resources because I
don't think that is true - but I'd like to see if it is and what the
logic used was to conclude that. Have any operators found they were
unable to afford more resources even though surely their subscriber base
is increasing?

(there are othe reasons for Australia's higher IP-per-Sub count, such as
legacy institutions with pre-CIDR allocations etc)
