Final answer:
The CIDR addresses for a network starting with 145.98 are best represented by option b) 145.98.0.0/24.
Step-by-step explanation:
The CIDR addresses for a network that starts with 145.98 would be option b) 145.98.0.0/24.
ba method used to allocate and route IP addresses more efficiently. It allows for the division of the IP address space into smaller subnets. The number after the slash (/) signifies the number of bits used for the network portion of the address. In this case, /24 means the first 24 bits are used for the network address and the remaining 8 bits are available for host addresses.
Option a) 145.98.0.0/16 would allocate a larger network with 16 bits used for the network portion and 16 bits available for host addresses. Option c) 145.98.0.0/8 would allocate an even larger network with 8 bits for the network portion and 24 bits available for host addresses. Option d) 145.98.0.0/32 would represent a single host address, as all 32 bits are used for the network portion.
