Change the ip address of my modem on my home network programatically

I have 3 computers routed to a modem via a router.  I am only concerned with 1 of the computers.
I have Xp on the computer with high speed cable internet.
First off...assume I have just heard of ip addresses today...I know very little about them.  I have learned today though that when I send an e-mail, the ip address of my modem is the one that the reciever on the other end can see...please inform me if this is not correct.
Also, from what I've read here so far...it appears that an ip address may not be able to be changed programatically at will...but what I would like to do is this...
Write a VB6 app that I just click the button and the ip address of my modem changes instantly, or somthing that at least would make my next activity appear as if it came from a different ip address.  I can write the code to come up with the random address...I just need the code to change the address of my modem and preferably not my computer's ip address..which would be the second ip address in line....(the computer is first, then the modem is next)
This has to be with VB6.  No 3rd party stuff...and preferebly not a link to a long complicated explanation or solution...cause I probably wouldn't be able to understand that anyway...:-(

Can this be done?

Thanks fellow experts!

So what you are saying is that I can't do what I want to do...right?  Just click a button on my app and have my ip address appear diffent to the outside world the next time I have any outgoing activity...

Without more information then I would have to say you are correct. Under normal circumstances you do not change your IP address without good reason. It can have devastating effects on your network connectivity.

Having said that, spammers and others who want to conduct unethical activity online create utilities that spoof (or mask) the true source of their messages.

If you would like to provide more information about why you are wanting to change IPs so readily and what you desire to gain then perhaps we can find a solution that achieves your goals without changing the IP.

Hi all...
Thanks to every one that commented here.  I've actually checked out the anonymizer site, and that will probably work for what I want to do, but this was suppose to be a learning thing for me also.  I've never known much about ip addresses or how they work.  There is a certain web site that I think has blocked me by my ip address, but I want to contact them, and the anonymizer I think will work for that.  But since I am an intermediate VB programmer, I was hoping to learn how to do this myself, learn more about ip addresses, how they work etc..., and I just wanted to do this programatically, do some testing and playing with it...and so on.  I got some code today that traces the route that a packet takes to get to any web site and gives me every ip address that it passes through along the way, starting with my computer, and I thought that was just totally cool!  It just kinda esculated from there.  Not a big necessity or anything but it was just something I wanted to learn how to progamatically do.  
But I learned a lot here today.  I had no idea that ip addresses were so permanant.
I thought they could be set and changed by the user with the proper knowledge, but I see now they cannot be.  But I must say again...I know an awful lot more now than I did 2 hours ago, so you've all still been a big help.
I'll just split points and call this question done.  Thanks to all who enlightened me here.

Well...I guess there were only 2 of you that commented here.  I thought there was more than that, but I was wrong.  I'll just split the points evenly then, and thanks again for all the info that you gave me!
