CIDR notation (e.g., /24) is used to represent IP address ranges and subnetting. The number after the slash indicates the length of the network prefix. residing on a sub-network with the following work address of this subnet? - (5) Question not attempted Ans: D - IP Address A unique identifier assigned to each device on a network. - Subnet Mask Used to divide an IP address into a network address and a host address. The bits set to 1 in the subnet mask correspond to the network portion, and bits set to 0 correspond to the host portion. - Network Address The first address in a subnet, which identifies the network itself. - Bitwise AND Operation To calculate the network address, a bitwise AND is performed between the IP address and the subnet mask. network, and the last 8 bits are for the host portion, with the first 4 bits of the last octet being network bits and the last 4 bits being host bits.
