Classful networks are obsolete. See RFC 4632.

Mutlicasts are limited to a *local* network segment. Unless a black
magic called IGMP proxy is involved.

Of course it's not pingable.
The whole point of 184.108.40.206/4 network is that there is no host that has
such addresses assigned, yet UDP packets should come to any host in a
*local* (in L2 sense) network segment. Assuming that said host wants to
listen such multicast address.
Also, RFC 1112.

Nope. There's no point in such backdoor as multicasts are not routable.
