Moved: This thread is more suitable in Linux-Security and has been moved accordingly to help your thread/question get the exposure it deserves.

The messages show you that your machine's receiving large number of strange packets with addresses that don't make sense at all. It's mostly informative. If you're the admin, it may be a good idea to trace the source down. You have interface they are from (eth0) and MAC number of the card that sent them (it may be false, but is worth checking). If you check all your machines and their NICs, you should be able to find it.
