It would not surprise me that pacbell/swbell aka SBC and Time Warner/Roadrunner are among the biggest offenders here. A significant portion of their customers are DSL/cable mode subscribers. Since Win2k and I assume XP both attempt to perform dynamic dns updates, hosts behind NAT, windows will happily send the update requests up the dns tree as far as it can. When @Home was around, the primary name servers for home.com used to see update attempts constantly. Paul Vixie has posted in here statistics about the root levels getting hammered by such update attempts in the past. Any technical solution performed at the network level would be a bubble gum and duct tape attempt to fix what was poorly engineered at the software level. Since it's unlikely Microsoft will issue some sort of fix to the problem. Perhaps IANA should set the name servers to an address within each particular block, that would at least keep the traffic local to the organization, and not hammer larger internet infrastructure name servers.
