An ISP is granted a block of addresses starting with 129.80.0.0/16. The ISP wants to distribute these blocks to 2600 groups as follows:   The first group has 200 medium sized businesses; each need 14 hosts. The second group has 400 small businesses; each need 6 hosts. iii. The third group has 2000 point-to-point links; each need 2 hosts. Design the sub-blocks and give the slash notation for each sub-block. Find out how many addresses are still available after these allocations.

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
