Question

. Compare and contrast the types of addresses used in a network and explain how address resolution works.   Give an example.

Answer 1

The network address is basically a identifier which is used to identify node or host on a telecommunication network. The network addresses are designed to uniquely identify accross the network. Some of the networks are allowed for local address, private address and locally administrated address which can be unique in the network.

The network address are-

1. Broadcast address- This is a network address in which all the devices of a network are connected to a multiple access communication networks which are enabled to recieve datagrams. The broadcast address can be IP address and can be MAC address.
2. Multicast address- In this address the specific group of devices are connected to the network.
3. Unicast address- In this address the single device is connected to the network.

Now we study about how address resolution works. It is also known as address resolution protocol(ARP). The main work of ARP is to find the hardware address or MAC address of a host from it's known IP address. Suppose if one device want to make communication to other. The device of the network take the header of the data link layer from protocol data unit which are known as frame and transfer the packet to the network layer where the network ID of the packet is validated the IP address of the destination. If it is equal then the ARP sends the information to the destination.

Example- Ethernet.
