      24.0/8 is the "cable block".  ARIN normally allocates residential

themselves are nearly always numbered in 10.0/8.

Perhaps "a cable modem block"?  We tell ARIN we need networks for
cable modems and have never gotten an allocation from this block.

        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.
