The host using the specified IP address answers with its hardware address. For efficiency reasons, these answers are cached during a specified amount of time, and hosts that change IP addresses might send a gratuitous response indicating their new IP address. Layer 3: The Internet or IP Layer As discussed previously, the Internet layer is responsible for handling the communication between hosts on the Internet, or to put it differently, it performs the routing function. It accepts a packet from the transport layer, turns it into an IP packet, and hands it to Layer 2 and vice versa.
DHCP is a protocol that can be used by hosts to find out which IP address they have to use on the network to which they are attached (other link-layer-specific approaches exist). To get an IP address, the host (the DHCP client) sends a broadcast message containing a hardware identifier (the MAC address). A server that is configured to administer the IP addresses replies to that message with an IP address and length of validity for that address (a lease). When the validity period is ended (the lease is expired) or the host moves to a new network, the host needs to ask for a new IP address.
Conversely, a large network can be divided into smaller subnetworks (this is called subnetting). Figure 2-5 illustrates network aggregation and subnetting. 128 / 28 Aggregation and Subnetting In essence, IPv4 packets consist of a host IP address, a destination IP address, and the payload containing the application data. Some additional fields are added to indicate the fact that it is an IPv4 packet, a checksum to detect defects caused by transporting the packet, and so on. Figure 2-6 illustrates the format of an IPv4 packet.
