Final answer:
An IP address always consists of a network part and a host part, which identify the network and the device within that network, respectively.
Step-by-step explanation:
The two components always found in an IP address are the network part and the host part. The network part identifies the specific network on which a device is located, while the host part identifies the specific device on the network. In IPv4, an IP address is typically divided into two parts by a subnet mask, which determines the size of the network and host portions. For IPv6, the separation is defined as part of the address structure, typically the initial 64 bits are the network portion and the next 64 bits are or include the host portion.
