Okay, firstly Enry (630!) the switch from address classes to CIDR actually became the problem. It caused a tremendous blow up in the size of the routing tables. IPv6 is a switch back away from CIDR, not all the way to classful but far enough to control the size of the tables at the cost of 'address overallocation'. Allocating each IPv4/32 independently would have required something like a 30GB routing table compared to the current IPv4 of quite a few megabytes and the IPv6 of tens of kilobytes.

The problem I was addressing wasn't routing - it was the lack of IP addresses and how just because someone has 18 million addresses doesn't mean that all of them are available.

This means that a /64 is the smallest network that will be allocated, as it contains 2^64 host addresses it's big enough for any private network.

Where have we heard that before? (j/k)

It doesn't need to be 18 million devices - each subnet is already dropped by two to have a gateway and broadcast address. It's also unlikely that every /24 will have all 254 remaining devices on it. At work I have a /22 and only have about 700 IP addresses assigned, but the rest are unusable to anyone outside my group.

This is one of the core problems with IPv4 (which CIDR) skirted around. IPv6 has this problem as well, but having more IP addresses available than number of atoms in the sun (or something like that) means even with a ridiculous amount of waste there's still plenty of addresses to go around. Heck, Hurricane Electric assigned me a /64 IPv6 subnet (2^64 addresses available)

You're also forgetting worldwide organizations that need to do a site-to-site VPN. Each site now needs to coordinate its internal addressing so there's no overlap. Going with IPv6 completely eliminates this need.

It's a difficult balance. I used to be them a few years ago before I was promoted and they're doing some of the same work I used to do (sysadmin rather than coding). Thus I have the technical skills to know exactly what they're doing and how they're implementing it. I always have to remind myself when they go a different course that it's no longer me that has to implement and maintain, so they can do it however they want as long as the project gets completed.

Barnes & Noble to spin off Nook?->

"The bookseller has been banking on the Nook for growth, so news that holiday sales of the basic touchscreen e-reader were disappointing raised investors' fears that Barnes & Noble was struggling to keep up with Amazon.com Inc's Kindle.""
