What is an IPv4 address made of?
Network Portion
Host Portion
Subnet Portion
Admin Portion
If all devices are on the same network, then
all of their bits are identical
all of their bits are NOT identical
all of their numbers are identical
all of their hex are identical
How do hosts know what portion of the 32-bit address is the network and what is the host?
Assigning an IPv4 address requires 2 parts; what are they?
IPv4 Address / Subnet
IPV4 Address / Default Gateway
Default Gateway / Subnet
Subnet / MAC Address
To access a remote network, a host computer needs
a default gateway
an IP address
a MAC address
a remote server
What does a subnet mask do?
The process used to identify the network and host portions of an IPv4 address is called
ANDing
ORing
ANGling
Logical
What is the number of bits set to 1 in the subnet mask called?
Subnet IP address
MAC address Subnet
Subnet Default gateway
Organize this subnet masks
255.0.0.0
255.255.0.0
255.255.255.0
255.255.255.252

11111111.11111111.11111111.11111100
Convert this binary IP to decimal
11000000.00000011.10000000.00000001
(a)
Logical AND is the comparison of two bits that produce the results shown below. Note how only a 1 AND 1 produces a 1. Any other combination results in a 0.
1 AND 1 =
(a)
0 AND 1 =
(a)
1 AND 0 =
(a)
0 AND 0 =
(a)
Explain logical ANDing.
Host Address 101.5.274.223
Subnet Mask 255.255.255.0
Host Address in binary 00001010 10011000 01001010 11011111
Subnet Mask in binary 11111111 11111111 11111111 00000000
What is the network address?
(a)
What is the slash notation for the subnet? (hint: something to do with bits)
(a)
Explain what can be a host on a network.
Host: 172.44.236.15
Subnet: 255.255.255.192
Network?
Hint: Convert Host and Subnet to binary -> then use ANDing.
(a)
Host: 172.149.212.184
Subnet: 255.255.255.248
Network?
Hint: Convert Host and Subnet to binary -> then use ANDing.
