Ever noticed that fat /13 for a certain military network in the ARIN

At least those /19 are justifyiable under the HD rules (XX million
customers times a /48 and voila). A /13 though, very hard to justify...

Also, please note that the current policies and "waste" (ahem) is only
for 2000::/3, if that runs out we can take another 7 looks at how we
should distribute address space without "waste".
Indeed the folks now getting IPv6 will have an IPv4 A-class advantage,
but heck, if 2000::/3 is full, we finally can say we properly deployed
IPv6 straight all around to the rest of the universe...
