by jmsfmtex / November 19, 2010 10:19 PM PST

Does the IP address change? I have a router,desktop, notebook, iPad-using applications that connect with an IP Address, iTouch-using iTouch applications that connect with an IP Address. Or is the IP address part of firmware?

No, it's not part of the firmware. It's either defined as a fixed IP-address somewhere in the OS, or the device gets it via DHCP from another device. Usually in home networks a PC connects to a router, and the router gives it an IP-address.

But you might find your modem has a fixed IP-address given by your ISP that it shows to the outside world. For dial-up it changed everytime you made a connection. For ADSL and cable it usually is fixed. Easy to try out by using any of the 'show my IP-address' sites available. That shows it.

To see the internal IP-addresses of your desktop and notebook, either use ipconfig at that device or go into the router management page and find where it tells you about the currently connected devices.

I have DSL through AT&T and live in a major metro area in the US. My assigned IP will change if I log off the internet for 10 minutes or more
