Maybe, if the equipment can handle the number of routes. I actually see =
two opposing things: the scarcity will require more fragmentation with =
smaller fragments, which requires less strict filtering. On the other =
hand the fragmentation will already start with e.g. /20s being =
fragmented into /24s. That might already cause problems for current =
hardware, which might cause people to filter more strictly. =
Unfortunately my crystal ball is broken at the moment.
When ARIN starts allocating /28s from the reserved /10 in =B112 months I =
wonder which direction it will go... I hope for the ARIN region that the =
majority of operators globally will loosen up their filters for at least =
that /10 within those 12 months so the allocations will actually be =
usable. For that to happen it would be very useful to know *which* /10 =
has been reserved in 2012 though... 12 months is not much for global =
communication, education and filter adjustments.
And anyway, who needs IPv4 a decade from now? ;)
Cheers,
Sander
