• IP address

• subnet

An IP address address is made up of _____

• 2 binary bits (1s or 0s)

• 64 binary bits (1s or 0s)

• 8 binary bits (1s or 0s)

• 32 binary bits (1s or 0s)

Rather than showing the IP address in its binary from, it’s easier to use a format called ______ where the 32 binary bits are broken into four octets

• jagged decimal

• dotted decimal

• human language

• analog

The value in each octet ranges from 0 to 255 decimal, or from 00000000 to 11111111 binary.

• true

• false

Each IP address has two parts. identify these two parts in proper order

• the first identifies the network and the subnet

• the second identifies the node (router or computer).

• the first identifies the node (router or computer).

• the second identifies the network and the subnet

IP addresses are categorized into _____ based on which numbers identify the network and which refer to the node.

• 6 classes

• 4 classes

• 5 classes

• 3 classes
