Hijacking of prefixes - IPv4 class E (was: Announcing 2003::/16 during tests of "shipworm")

[Michel Py]

6bone folk,

In IPv4, there is something called class E (first bits 1111, 240 to 255)
that is "Experimental ".

The 6bone, IMHO, is not big enough in some experimental situations.
There will be a few protocols (think about 6to4) that need the full 32
bits between the TLA and the SLA, which means they would need a /16 to
test.

Maybe it would be a good idea to create IPv6 "Experimental prefixes",
allocate to it a handful of IPv6 /16 prefixes, well know to host wild
experiments, that everybody could choose to filter or not.

Michel.
