------> IGP learnt networks .. a small tweaky bit which learns broadcast
addresses via the networks in the IGP wud help (again summarization wud make
it bad)

-----> a very small percentage cud be blocked if u were willing to link this
to BGP learnt networks..at least those are "complete networks", not
subnetted....

ofcourse its a very small portion, mebbe u cud ask guys to send more
specific BGP routes from now....
