My ISP assigns my home network a dynamic IP. How then does every computer on my home network have its own IP as well?
Your home network is most probably run via a central router, which may also contain a modem (if it’s any kind of DSL connection, and you have your Internet line plugged into your router directly) then the router will contain a modem. Just about all routers nowadays designed for home usage have a DHCP server inside them – DHCP standing for “Dynamic Host Configuration Protocol”, where the DHCP server communicates with the network cards in the computers connected to it automatically and assigns them all IP addresses on a private, separate network (often in the format 192.168.1.x, where x is a number between 1 and 255, but this format can differ slightly).
