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

http://www.iana.org/assignments/network-24

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...

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