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.
This seems like an unwise overlaying of the IANA-RESERVED space to me. Why can't IANA allocate itself a /20 (or whatever it needs) and keep IANA-RESERVED space for unallocated addresses (plus maybe experimental uses that can and should be filtered at every border). Regards Marshall Eubanks that

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.
