Cable probably has a significant portion of the *residential* broadband market. Business customers use DSL since cable does not reach most businesses. Even if it did most businesses would reject cable because of the security issues and service blackouts inherent in a shared network. 2600 magazine has monthly articles on how to steal MAC addresses to implicate innocent cable users in DoS crimes.
Businesses don't want to put up with such foolishness.
In my opinion cable is inferior to DSL. My guess is that you agree with me. The reverse lookup on your IP address indicates that you are posting from a DSL line.
2600 magazine does not sanction any illegal activities of hacking whatsoever. 2600 magazine does show readers how they could be possibly be attacked and how to seal up such holes in there systems. I have learned quite a bit from that magazine and have helped my sys admin make sure our network is secure. Please do not add to the governments fear campaign of hackers.
