Hello, I replaced the logic board on my PB G4 1.5 Ghz and noticed the IP address is the same as the previous motherboard. I thought every computer had it's own exclusive IP address with it's own identity. So my question is: Where is the IP address stored on my mean machine?

Thanks from oregon

Isn't the ISP the one that set up your IP address?

You confuse the IP (Internet Protocol) address, which is not entirely unique (you have an internal IP to connect to the local network, which is connected to a router and modem, and the modem has an external "unique" IP to connect to the internet, an IP looks like 192.168.1.1 (internal) or 10.0.1.4 (internal) or 83.212.9.32 (external).

You mean the MAC (Media Access Control, not to be confused with "Mac", which is short for Macintosh) address, which is using the hexadecimal system.
A MAC address looks like 0a:25:0g:fe:20:7e.

To check your wired MAC address, open Terminal and enter
ifconfig en0 | grep ether
to find the wireless MAC address:
ifconfig en1 | grep ether

Is that understandable?

Depends on which IP we talk about, but yes, the ISP is responsible for the external IP.
