What is the first part of an IP address called?
The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. An example of a Class A IP address is 102.168. 212.226, where “102” identifies the network and “168.212. 226” identifies the host on that network.
What is N in IP address?
Therefore, if a network has a mask of /n, the first n bits of the IP address are the network bits. The remaining (32-n) bits out of the 32 bits of the IPv4 address represent the host part of the address. Since the IP addresses are unique, in a subnet the maximum number of host addresses is 2(32-n).
What do the first three bytes of an IP address represent?
The classful paradigm tells us that the first three bytes of the address represent the network portion, whereas the last byte represents the host portion. Well, when subnetting, we want to create subnets out of the network; the network bytes are fixed and so we are going to need to use some of the bits dedicated to the host as subnet bits.
How are IP addresses used in a network?
To uniquely identify each computer or networking device in the network, computer networks also use addresses. Addresses in computer networks are known as IP addresses. An IP address consists of two components: the network address and the host address.
How is the class of IP address determined?
The class of IP address is used to determine the number of bits used in a class and number of networks and hosts available in the class. In Class A, an IP address is assigned to those networks that contain a large number of hosts. The network ID is 8 bits long.
Is the IP address in a network subnetting?
It does not possess subnetting. The higher order bits of the first octet is always set to 1110, and the remaining bits determines the host ID in any network. In Class E, an IP address is used for the future use or for the research and development purposes. It does not possess any subnetting.
