    Study Notes

    Network Part of an IP Address

    • Identifies the specific network within a larger routing structure.
    • Ensures data packets are sent to the correct destination network.

    Limited Broadcast in IP Addressing

    • Allows a message to be sent to all hosts on the local network segment.
    • Uses the broadcast address 255.255.255.255 for this purpose.
    • Facilitates communication when the specific IP addresses of hosts are unknown.

    Division of Network and Host Parts in IP Addressing

    • Historically, the separation used subnet masks and classes (A, B, C).
    • Classful addressing defined fixed boundaries between network and host portions.

    Class B IP Addressing

    • Supports a total of 16,384 available networks.
    • Each Class B network can contain up to 65,534 hosts, promoting scalability.

    Loopback Interface in IP Addressing

    • Designated IP address 127.0.0.1 is used for testing and diagnostics.
    • Allows a host to communicate with itself, enabling software and protocols to be tested without requiring a physical network connection.
