Re: IRR listing of IANA-reserved, a question..

They are not bogus, hence the sub-deligation, and hence a 
good reason to have a more detailed source of information.

I would suspect that this block should be "chopped" a bit to
reflect the IANA/ICANN usage.

This block was first routed on the internet via AS 226 around
late summer early fall 1999.
