Yes, but the network stack doesn't necessarily need to be in the kernel (in
fact, for microkernels it never is). In any way, you don't need to look at
multicast to find DoS attacks in the internet. The internet is not robust
against DoS by design (that's a good thing: it has allowed to grow the
internet quickly, and the advantages of that outweigh the lack of security by
By the way, by multicasting I was refering to X-to-many IPC (as the poster I
replied to did).
