No it's not.  Check out 24.132/14 for instance.

IANA and ARIN seem to think it is... Check out:

The "Network 24 - Cable Block" will link to the following text:
 
 Internet Assigned Numbers Authority (IANA)
 Date: May 11, 2001
 
 The IANA has completed the administrative transfer of responsibility
 for 24.0.0.0 - 24.255.255.255 (Cable Block) to the American Regional
 Internet Registry (ARIN).
 
 Questions or Whois information for this 24/8 block should be directed
 to ARIN <www.arin.net>.

I'm sure a few legacy allocations in 24/8 space will happen to slip
through...

 Nearly all the cable operators
have one slice or another from this block.

Perhaps this is true in the US.

 Nearly all North American
cable modems users have address space in this block.

No they don't.

Well since I don't think you can argue Canadian cable modems follow
different patterns, you seem to have contradicted yourself...

Didja ever have a bad hair day, when you just felt like being contrary
for the hell of it?

You think thats funny, until Extreme switchs starts shipping with your
IP null routed by default... :P
