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.

Just out of curiosity, do you know that these are bogus source 
addresses?  Some of the IANA-RESERVED block is actually valid and is 
used by IANA's computers.

My company was blocking all of the IANA-RESERVED space for a while, 
until we discovered that the IANA web server is using an address in that 
space.

Various people have reported seeing IANA-RSERVED get announced
via BGP at different parts of the net.

Again, bogus addresses or legitimate IANA servers?  Not everything in 
IANA-RESERVED is bogus.
