224-239 are multicast addresses. Making it /4 makes the entire multicast
address space one network block which is about as reasonable an answer as
anything else.

I guess Vixie figured network blocks subdividing multicast address space
weren't a sensible concept? It's a bit of a strange constraint to hard code
into the C code though.
Incidentally, how can that code possibly work? It treats odst as a pointer in
some places but then calculates bits using arithmetic on it directly without
dereferencing?
