The DHCP protocol is used for this purpose.
A DHCP server will assign addresses and network masking automatically.
The feature that assigns your network IP address automatically is called DHCP, or Dynamic Host Configuration Protocol. DHCP allows devices on a network to receive IP addresses and other configuration settings automatically from a DHCP server, eliminating the need for manual configuration. This process ensures that devices can connect to the network quickly and efficiently with valid IP addresses.
A DHCP server will assign IP addresses, and other network parameters, automatically, to computers who ask for it. In Windows, if you select that you want the computer to get an IP address automatically, it will try to get the IP address (and other parameters) from a DHCP server.The idea is to reduce the amount of configuration required for each computer, especially in larger networks.
The benefit would be to automatically assign network addresses to clients that need them to work on a local area network. Without DHCP you would have to assign each device an address, subnet mask, and default gateway, plus DNS and WINS server addresses, which can be time consuming and error prone. With DHCP, most of those problems disappear.
You have to have 2 network cards in the computer. I can not thing of any other way of doing something like that. Why would you need 2 address for a computer anyways?
No, Windows normally assumes that the network uses DHCP and it attempts to find a DHCP server on the network. If it cannot find one it will eventually assign a 169.x.x.x address but it will not assign the gateway or the DNS addresses when it assigns the 169.x.x.x address.

That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned. Any time a host (computer or similar) requests an IP address, the DHCP server will assign an available address and mark it, in its memory, as "assigned" so it won't assign the same address to another computer.That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned.

I think you're thinking of the protocol used to automatically assign IP addresses? An IP address does not assign an IP address, and IP address is a node on a network where data can be sent or received. The protocol used for automatic assigning of IP addresses would be DHCP (Dynamic Host Configuration Protocol).
254 - a class C subnet uses 8 bits for the hosts and 0 and 255 are reserved.
