    Study Notes

    IPv6 Loopback Address

    • IPv6 equivalent of the loopback address 127.0.0.1 is 0:0:0:0:0:0:0:1 (or simply ::1).
    • Loopback addresses in IPv6 are reserved similar to IPv4.

    Class B IP Address

    • Class B addresses range from 128 to 191.
    • 129.16.12.200 is classified as a Class B address; others are Class A or C.

    DHCP Server Failure

    • Systems with an IP address from the 169.254.x.x range indicate a failed DHCP server configuration (APIPA).
    • An address of 0.0.0.0 typically means the system lacks APIPA support, not a normal DHCP failure.

    IPv6 Address Types

    • IPv6 employs three main address types: unicast, multicast, and anycast.
    • IPv6 does not use broadcast addressing, unlike IPv4.

    Private IP Address Ranges

    • Recognized private IP ranges include:
      • 10.x.x.x
      • 172.16.x.x to 172.31.x.x
      • 192.168.x.x
    • 127.0.0.1 is for loopback and not a private range.

    Recognized Private Address Ranges

    • 131.16.0.0 to 131.16.255.255 is not a private IP address range.
    • Private address ranges include those within 10.x.x.x, 172.x.x.x (specified subnet), and 192.168.x.x.

    Subnet Mask Configuration

    • For an assigned public IP of 203.15.226.12 with /24 notation, the subnet mask is 255.255.255.0.
    • /24 indicates that the first three octets are used for the subnet mask.

    Subnet Value Issues

    • Spencer’s subnet mask of 255.255.248.0 is incorrect compared to Evan’s 255.255.255.0.
    • Both users should share the same subnet mask for proper communication.

    Default Gateway Function

    • The default gateway provides routing paths for local networks to reach external destinations.
    • It enables inter-subnet communications; incorrect interpretations describe its role inaccurately.

    Hop Count Definition

    • Hop count refers to the number of intermediary devices (hops) a data packet passes through to reach a destination node.

    Router Assignment Protocol

    • The Virtual Router Redundancy Protocol (VRRP) automatically assigns routers to hosts for improved routing reliability.

    Traffic Monitoring on Switches

    • Port mirroring allows visibility into the flow of inbound and outbound traffic on a switch.
    • This is crucial for monitoring network performance and troubleshooting.
