The Internet Sky Is Falling

For years there have been fears that IPv4 addresses were running out, and the Web would be more paralyzed than the U.S. Congress. I had the honor of interviewing Vint Cerf on this very subject over ten years ago, and came away a bit nervous. Cerf's answer? Move over to IPv6.

As I understand it, there were some tweaks (kludges?) to IPv4 that expanded the address space and bought us an extra decade or so. Now that time is running out, and without a new kludge, we could be plum out of IPv4 addresses, tout de suite.

According to Internet registries, the situation is so bad that all remaining addresses could be gone by the end of the year.

The real issue is that converting to IPv6, even though it's been available for many years, ain't always an easy thing. But again, you are the experts. Is IPv6 a piece of cake or a piece of something else? Tell me at dbarney@redmondmag.com.

JVM2009, If you think Mindows (LOL!) can't connect across two different private address space networks, I suggest you check out the microsoft website http://technet.microsoft.com/en-us/library/ff687823(WS.10).aspx You CAN connect across private address space without problems.

jmv2009, Mindows networking between two systems on two different private networks is not an issue. Thats what gateways and VPNS are for.

I agree - pull back the millions of addresses that the big corporations have, and there'll be enough addresses for everyone!! Why can't that one simple thing be done??!!

If a SINGLE IPV4 address would have been given out to each company (using that single routable IPV4 address as the forward facing router/firewall address) and the companies, in turn, ALL used private address space in their internal networks (192.168.x.x, 172.16.x.x or 10.x.x.x) there would be more than enough IPV4 addresses to go around... Instead, corporations get a full Class A, B or C range to themselves. DUH! Make companies return their multitudes of registered address space back and implement private address space! After all, the private address 10.x.x.x is able to host 16,777,216 addresses....
