It had 16 remaining nodes 12 years ago, which is the last we heard from it.

mips big endian test is good. Endianess always bites me on the wrong
side of the egg.

only 225/8-231/8 are opened up from the relevant reserved for
multicast space by this patch series. They have always been unassigned
addresses. I did not change the userspace IN_MULTICAST macro, but
nearly nothing in userspace checks that.

224/8 is used by a half dozen common applications and reserved by a
few hundred old ones. Theoretically we could use 224.6/16 and up but
it was simpler to do 224.

232 and up is unclear.
