|  Comcast IPV6 plans have an interesting component ....
... multiple users sharing an IPV4 address.
And that brings up all kinds of issues for web sites that block users by IP address; for RIAA/MPAA watchdogs that track users by IP address; etc. If multiple users are using the same IP address, how are they going to police things with existing systems.

Comcast's idea is to allow many broadband customers to share one global IPv4 address instead of providing one global IPv4 address per customer.
"The exact ratio of IPv4 addresses to customers is something we are studying right now," Durand says. "We are working on some tests to see if it is 1-to-5, or 1-to-100 or 1-to-200."
The trick with sharing public IPv4 addresses among many customers is doing it in the simplest way, Durand says.

| Umm, these are the **AssAss's, they will just sue all 200 people. They don't NEED any proof, if they collect from just 1 of the 200 people, they have paid for it.

Wow, Comcast's plan certain gets placed in the top five bad ideas of the networking world for the year with that one.
Not only do they have to deal with the problem of blocking per IP, sharing an IP as proposed is a great way to break applications, increasing router CPU load and in general, create all sorts of problems. Take the example of multiple users behind that IP trying to use a game like Half Life which runs on a set port - the two clients will never be able to be online simultaneously.
Definitely not the best or wisest idea I've seen presented. Comcast really needs to go back to the drawing board.

| Couldn't have said it better. There are WAY too many LEGITIMATE applications that still require a set forwarded incoming port to operate properly. Not to mention, like you said, many applications/games do not like multiple users connecting from behind the same NAT router due to that limited set of ports needing to be forwarded.
And that's just the tip of the iceberg. It would be logistics hell to even manage a system like that to allow ports to be forwarded to customers and not only prevent it from being abused, but keep CSR calls at a minimum.
If Comcast really thinks this idea is going to fly, I expect a MASSIVE slap in the face by the world at large before it even gets off the ground.

I swear, some people should have pace-makers installed to free up the resources. Breathing and heart beat taxes their whole system, all of their brain cells wasted on life support.-two bit brains, and the second bit is wasted on parity! ~head_spaz |
