Robert,

Should the InterNIC allocate *every* ISP addresses from a reserved /16?
Or just certain ones?  Or maybe only the ones that ask for it? (Which
happens to be almost every one).  I'm not trying to be facetious here,
it's just that in my experience, 90% of the ISPs that I deal with
believe they deserve at least a /16 as a first or second allocation.

As I stated before, we do reserve from larger blocks now but not
necessarily /16s.  I'm not sure about the case above - but the 204/8
block hasn't been allocated from in a long time so his blocks were
probably issued before we started reserving from larger blocks.  We
all live and learn :-)
