Thus spake "Donald Stahl" <[EMAIL PROTECTED]>
The upside is that in the block you're expected to accept /48s,
nobody will have a /32. The downside is that anyone who gets
a larger-than-minimum sized allocation/assignment can
deaggregate down to that level.
I don't think ARIN is planning on giving out more less a /48 but
more than a /32- at least that was the impression I got. End sites
get a /48- ISP's get a /32 or larger- and that's it (I could certainly
be wrong). As such, deaggragation in the /48 block should not
be an issue because no one will have more than a /48 in the
first place.
Current policy allows for greater-than-/48 PI assignments if the org can
justify it. However, since we haven't told staff (via policy) what that
justification should look like, they are currently approving all requests
and several orgs have taken advantage of that.
So, it's entirely possible someone could get a /40 and deaggregate that into
256 routes if they wanted to. Given the entire v6 routing table is around
700 routes today, it's obviously not a problem yet :)
