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.

and:
$whois -h whois.arin.net 192.0.34.69
IANA RESERVED-192 (NET-192-0-0-0-1)
192.0.0.0 - 192.0.127.255
ICANN
c/o Internet Assigned Numbers Authority ICANN (NET-192-0-32-0-1)
192.0.32.0 - 192.0.47.255

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.
