First off, you should talk to your ISP.

My ISP attaches an IP to a MAC address and I get the same IP for months at a time. I've never called them or checked, but it seems like about every 6 months I get a different IP address.

I can shut my modem and/or router off and I'll still get the same IP when they reboot. I can also release and renew and I'll still get the same IP address. So if your ISP does things like mine, you can't really do much at your end to change your IP. Reboot your router and modem, if you get the same IP back, then chances are, your ISP does things similar to mine.

Therefore my suggestion. If you call your ISP and discuss what's going on with them, they can change your IP for you even if they do things the same way mine does.

An alternative to changing your WAN IP would be for you to use one of the many proxies available on the internet. If you go through one of them, your IP will appear to have changed on any site you go to.

How charged with punishments the scroll,

I am the captain of my soul.

It is even simpler. Unplug it for one minute.
Once you unplug the router, your ISP will free up the IP address for future use and reassign a new one when it 'sees' your modem again. Waiting a minute is to ensure that their system recognizes the disconnect and not as a momentary break in communication.

You have to be a little bit crazy to keep you from going insane.

I will try, thank you for your time. I will be back with results when I get off work.
Just the power or cable and power?

Just power. And it depends on the dhcp lease. Just turning off won't get you a new lease. And why do you think you need a new wan ip?

Answers are only as good as the information you provide.

Knowing you public IP address will not enable anyone to stalk you. thye need more than that or a very big hole in your security,

If you have your router configured correctly then you public IP address is useless. You do have a router don't you?

Secured wireless, but I guess I am paranoid. I want all new addresses. Someone is trying to track me down. I heard from a friend via a PM on another forum. And the person tracking or trying is in that business of being a digital and computer detective. NOT LEO. I just said some things that offended him. I don't want to use same public WAN # when I go back on that forum. Did I mention I was paranoid?
How can I release that DCHP lease and then renew?

What difference will it make. The only people that will know you public IP address are the owners of the forum server. Other users have no way of detecting your public IP address.
