Key comment
Many commentators are referring to the coming IPv4 address crunch as another Y2K. Given that Y2K was less of a disaster than predicted we might as well hope that this is correct.http://www.i-programmer.info/news/81-web-general/1089-less-than-a-year-of-ip-addresses-left.html
Just in time or maybe ?? years too late IPv6.
This is not as serious as it seems. What is happening now is that ISPs are making a gold rush to gather all the IPv4 addresses they can, which is depleting the address pool much faster. However, there is a huge difference between having all the addresses allocated and having all the addresses in use. There are companies with entire Class A address blocks (IBM, HP, Apple, etc).
I think that we will see a restructuring of the IPv4 Address space to regain some of the unused addresses. Also ISPs will make more efficient use of available addresses, such as giving subscribers a private address instead of a publicly routed one, then charging $5 or so a month per public address. Most users have no need for a actual address, and many millions of addresses could be reclaimed in this way.
With proper management we can continue to use IPv4 for some time to come. Internet providers do need to be IPv6 ready for when we do finally need it, but this is not as urgent a need as some (mainly network hardware vendors ahem Cisco ::)) would lead you to believe.
