How can an IP address be forged?

IP Addresses cannot be steal!

Static IP addresses are assigned by your ISP. Typically, it's something you need to pre-arrange as part of setting up your account. The ISP determines what IP address to assign to you, tells you what that IP address is, and then configures their equipment to make sure that all data sent to that IP address is sent down the correct wires to reach you.

Dynamic IP addresses are also assigned by your ISP, but in a completely different manner. When you connect your computer or router to the internet, the software asks via a protocol known as DHCP (Dynamic Host Configuration Protocol) for an IP address.
