RE: End of IPv4 !!

Moazam,

When I was a school boy they told us "Sky's falling! Only 4%
remaining!", when I left the school they shouted at us saying "Danger!
Only 4% remaining!", when I worked for the vendor I was told that only
4% was remaining, and when I got my CCIE they asked us to learn IPv6
because only 4% of IPv4 space was still available. Today I'm hearing the
same thing. This sky has been coming down for more than 20 years and
except some US based SP's no one is 100% ready for IPv6, so I don't
listen to this kind of rumor anymore :) - they scream today and release
a couple of big /8 blocks tomorrow; don't take them serious; let them
play with their counters.

You may be right that exhaustion of v4 public IP space is eminent, but
v4 has a hell of a long way to go before its dead.

You should probably check out NANOG and the IETF mailing lists about
the various operational and (from a vendor standpoint) implementation
issues and modifications.

Even thought the government is requiring v6 support for equipment,
they have not been implementing it. (I remember another case where the
government thought IP would be dead.. CLNS...and we know what happened
with that)
