Just out of curiosity, do you know that these are bogus source

used by IANA's computers.
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.
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
$dig www.iana.org a

www.iana.org. 68055 A 22.214.171.124
$whois -h whois.arin.net 126.96.36.199
IANA RESERVED-192 (NET-192-0-0-0-1)
192.0.0.0 - 188.8.131.52
c/o Internet Assigned Numbers Authority ICANN (NET-192-0-32-0-1)
184.108.40.206 - 220.127.116.11
Again, bogus addresses or legitimate IANA servers? Not everything in
IANA-RESERVED is bogus.
Various people have reported seeing IANA-RSERVED get announced
via BGP at different parts of the net.
