Can't you just unplug your Router? When it reconnects won't it give you a new external ip ?

Seems to me to be the weakest form of attack against a "home setup".

Restarting the router will not necessary give you new IP address, it depends on the ISP. If you're on cable where router' MAC address is tied to your account, most probably you won't. If you are on DSL or with PPPoE authentication, most probably yes.

Not necessarily. Often, you get the same one.

The ISP may have a small block of IP's per neighborhood.
Or, their DHCP says "Oh look, here's Brewskee's router again. Lets give him the same IP address, because I don't want to think about it much."

All depends on the setup and policies of the ISP.

Also, even if you change your IP address, if your router is weakly configured from external threats, the simple IP address change won't protect you.

Check here for some simple steps to ensure your router is as safe as you can make it:

BTW, unplugging the router certainly protects your network when it is powered down. I know several folks who do this as a matter of personal network security.
