I'm just a little CCNA, I don't know what IP multicasting is (yet!),
but I believe class E networks have 4 higher order bits set to 1,
ie 240 - which explains why Class D's end at 239.255.255.255
(I think!)

Subject: IP Multicast Addressing
I'm reading through McGraw Hill's BUMS book. Chapter 7 deals with IP =
Multicast Addressing. I understand that class D addresses are used =
(high order bits set to 1110), but a statement used in the book confuses =
me:
IP Multicast addresses start with 224.0.0.0 and end with 239.255.255.255
I'm not real keen on where the 239 came from...
Thanks All !!!
