No, "The Cable Block" is correct parlance. Jon Postel
himself designated it as such in the mid/late 90s. It is the only
block that consists *entirely* of cable modem allocations.
However, you must have been late to the party. 24/8 appears
(not certain) to be fully allocated, so later allocations seem to be
coming from other address blocks.
