While I could agree that its not a problem till someone tries to use it,
I point out that ARIN does make an announcement when they are going
to start issuing from a new IANA block.

We, The Net Operators, should have this information so that we can update
our filters, should we see fit to, and thus cause as little negative impact
as possible.  

Several of the sample filters I have seen just drop anything that is currently
NOT in the IRR space, otherwords the IANA reserved spaces, like 80/8

*******

In fact if I remember correctly from the recent RIPE-39 meeting, its 80/7 that
they will be alloc'n from.

Not to invite a flamewar or anything, but it's not really
an operational issue until some operator tries to route
whatever they are allocated by the IRRs (RIPE, ARIN, APNIC).

None of the IRRs (or ICANN) can really make ANY promise
whatsoever that their allocations are globally routable.

(This will be particularly true of ever-longer prefixes
as they are allocated by various IRRs.   IOW, who cares
if the IRRs hand out /32s or /128s - just so long as 
people understand that the odds of global reachability in
both steady state and during convergence [*] decrease 
roughly proportionally to the length of the prefix).

So, this could well have been the first time an operator
has found an operational issue with 80/8 that is relevant
to the NANOG audience. :-)

You're very welcome - hey, first public-act-of-smd in many days.
