For residential use, for users currently requesting one public address,
that's a waste of a /30 block (sans routing tricks requiring higher end
customer equipment). Multiply that by the number of residential customers
you have and that's bordering on mismanagement of your address space.

If you're dealing with business customers, then your usage versus wasted
ratio is much higher and less of a concern, but what's the point? Are you
trying to cut down on a large broadcast domain?


Any rational layer 2 access gear regardless of the technology (DSL, FTTx, wireless, or DOCSIS) will/can handle layer 2 isolation already.
