    - IP :

        - The IP which stands for Internet Protocol is the network layer protocol.

        - It is used for routing the data from the source to its destination.

        - Every datagram contains an IP header followed by a transport layer protocol such as, TCP or UDP.

        - IP does not provide error reporting mechanism.

        - In IP, error checking and controls are not concerned.

    - ICMP :

        - ICMP (Internet Control Messaging Protocol) is an addition to Internet Protocol to carry error, routing and control messages and data.

        - It is also considered as a protocol of the network layer.

        - It differs from transport protocols such as TCP and UDP, in that it is not used to exchange data between systems.

        - ICMP has error reporting mechanism.
