Demand for multicast addresses was grossly over-estimated and no
|
|
viable new addressing mode for class-e ever appeared.

|
https://tools.ietf.org/html/rfc1112#section-4
|
|
|
|
1981: Class E IP addresses, i.e.,
|
|
those with "1111" as their high-order four bits, are reserved for
|
|
future addressing modes.
|
|
|
|
In the interim, since the last attempts at making class-e addresses
|
|
work, for some purpose (), most operating systems and stacks chose
|
|
to treat 240/4 as globally reachable unicast, and those that didn't
|
|
(windows only, so far as we have found), not allow them at all.
