tuff networking question

Im about to start an expensive venture to streamline some of my marketing. Im wondering how information is sent over the internet-among other things. In the end I need 1 pc to have 120 static ip's, 120 mac addresses and 120 ipv6 addresses to match another (more expensive system) that is already working. I already have the ip's working on a windows machine with a batch file that easily changes ip for me, but im worried about having the same mac address and ipv6 address as I want all traffic to be 110% unique.

I dont even know if other sites (c-li$t) can look at a pc's mac address. I have been told 100 different things like:

1. it is possible to take packets apart and see the actual pc's mac address
2. that the mac address is stripped out by router so changing it doesn't matter
3. that you can set up a router to NOT replace pc mac address with router mac address
4. that you CANT mess with the router Mac at all and u are always going to be sending packets out like that no matter what router/isp/connection you have
5. that there are some different ways of setting up routers and some hosting providers have unique - router/modem mac addresses.
6. that ipv6 addresses are not ever used and not included in packet

I want to do this in a way to not just send and receive traffic, but to be look exactly like a situation that is 120 different people, on 120 different pc's, that way I never have to change anything-even if it would work otherwise.

Where would you go to learn how this all works? Any help would be really appreciated...

see the answer below! I cannot delete this post..

Well, as far as the mac address goes, you can easily change it on your PC (which I guess you don't need, since you're using a router) or on a router (depending on the router). I'm not sure what kind of ISP do you have, but thous who provide you with their own router/modem, probably won't let you change the mac. There are still ways around it, but I'm sure mac address is the least of you concerns, since websites can't get your mac address, the mac addresses are transferred vai data link layer.

The problem you're facing is that you're probably going to be able to trick many hosts that the users are actually individual, but more advanced hosts will detect that the requests are coming from the same network and probably the same user. If you're going to use thous IP's for CPA signups or something, make sure you also change the user agent and clear cookies.

I would run a packet sniffer when you're testing what ever you're trying to do, to see if there is no trace that the packets are sent from the same host. Also, when the remote host is going to check your logs and all of your ip's look the same, only the last digits change, they're going to get suspicious. Hope that helps!

+1 for what RottenYellow said. I wrote app a year ago for SWIM that covered the bases he mentioned. There is a lot to watch out for and the learning curve can be steep. One misstep (such as the wrong IP leaking out) and all your work gets flushed and you have to start over. It's an interesting problem. Drop me a pvt msg if you have any specific questions; I might save you some time.
