In the last 72 hours I've seen over 3GB of data hit a network I play with with source IP's of IANA-RESERVED space.
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.
