Not that I know of; but
ALL:224. 225. 226. <etc>
would handle it.
However, you want the old Class D which can easily be covered with:
ALL:224.0.0.0/240.0.0.0
This _looks_ like your range; but it's really a mask that blocks every IP that
starts with 224-239 (1110xxxx...)
BTW, are you absolutely sure you want to block this range..? Routing protocols
and other multicast services reside in this range.
