• Calculate the number of available IP addresses

What is the purpose of subnetting in networking?

• To increase network traffic and slow down data transmission.

• To limit the number of devices that can connect to the network.

• To waste IP addresses and make network management more difficult.

• To efficiently use IP addresses and reduce network traffic.

• number of bits in the subnet mask

• 2^(number of borrowed bits)

• number of hosts in the network

• number of octets in the IP address
