IP Addressing

IPv4 addresses are

• 32 bits wide
• 48 bits wide
• 4 bits wide
• of any size in bits

The left-hand part of an IPv4 address is

• the Network-id

• the Host-id

• the MAC address

• the computer's memory size

The right-hand part of an IPv4 address is

• the Network-id

• the Host-id

• the MAC address

• the identity of the computer's network card

The biggest decimal number in any part of an IPv4 address is

• 255
• 256
• 100
• 1000

The lowest IP address in a range is reserved for

• the network identity (the subnet-id)

• the broadcast address

• the MAC address

• the computer's IP address

The highest IP address in a range is reserved for

• the network identity (the subnet-id)

• the broadcast address

• the MAC address

• the computer's IP address

A /24 netmask means

• a set of 256 IP addresses
• a set of 128 IP addresses
• a set of 64 IP addresses
• a set of 32 IP addresses

A subnet can only start

• on a multiple of its size
• at the number 0
• at the number 255
• at the number 1

A /27 netmask means

• a set of 256 IP addresses
• a set of 128 IP addresses
• a set of 64 IP addresses
• a set of 32 IP addresses

What is the dotted decimal netmask for a /27 network?

• 255.255.255.0
• 255.255.255.128
• 255.255.255.192
• 255.255.255.224
