Your PS3's IP address is either assigned by your router, if you're using one. It will appear as 192.168.0.xxx Or it is assigned by your modem if you are not using a router.
Your IP address could constantly change, if it is not static, unlike your PS3's MAC address, which is always the same.
An internet Protocol (IP) address is an identification number that is assigned to every device that is connected to the Internet. Each IP address is unique; it consists of four sets of numbers that are separated by three dots. Your PlayStation 3 console will have an IP address if it is connected to the Internet. Your PlayStation 3's IP address can be found by accessing the console's "Settings" menu.

Automatic Private IP Address was basically made so that clients which could not get an IP address automatically from a DHCP server could configure its own Private IP address until it can obtain address from the DHCP server which will override the APIPA and become the new IP address.
Reverse Address Resolution Protocol, obsoleted by BootP and DHCP, allows a computer to obtain an IP address after it has obtained an ethernet address. Bootstrap Protocol allows a computer to obtain an IP address when the operating system is starting up.
Reverse ARP is used to Obtain IP address from a Server(responsible for IP addresses allocation) by providing its layer 2 (MAC) address.

An e-mail address is not associated with any specific IP address. The only IP address that you can obtain from an e-mail address is the SMTP server that initially delivered the e-mail, not the machine from which the e-mail originated. The e-mail headers may contain the IP address of the original machine, however bear in mind that e-mail headers can be easily forged.
