Re: When IPv4 will exhaust?

Thanks a lot ... I appreciate your answer and regarding applications your
views are correct. Most of the applications at some point use "hard coded"
ip addresses or simply not aware of IPv6 completely. What i can understand,
may be "networkers" part will be much simplified than OS/Applicaiton Vendor
side. OS admins and application vendors may be are in different boat than
"networkers". For such migration It need a lot of effort coupled with huge
investments on their part.
Although IPv6 will exhaust sooner or later, its just a short time but can we
find out when non-networkers side will be ready to adopt IPv6 without seeing
any monetary benefits? Is there any thing which IPv4 cannot do and a IPV6
native "killer" application will do? Until a "killer" application is in
market, there is no compelling reason for OS/Application vendors to go with
IPv6.

Just my 2 cents..........
