while the last octet is called
Host Portion
Picture of Network and Host Portions
The Subnet Mask
IPv4 address - This is the unique IPv4 address of the host.
Subnet mask– This is used to identify the network/host portion of the IPv4 address
Example of IPv4 confugiration on windows computer
Logical AND
This is used to determine the
Network Address
1 AND 1 = 1
0 AND 1 = 0
1 AND 0 = 0
0 AND 0 = 0
Example of Logical AND in IPv4
Prefix Length
Method of expressing the subnet mask
Example of Premix Length
Network, Host and Broadcast Addresses
Network Address - Host protion all 0 (.00000000)
First Host Address - Host portion all 0 and end with 1 (.00000001)
Last Host Address - Host portion all 1 and end with 0 (.11111110)
Broadcast Address - Host portion is all 1 (11111111)
Example of network, host and broadcast addresses
IPv4 Communication
Unicast
Process of sending a packet from one host to an individual host
Unicast image
Broadcast

Public and Private Addreses
Public
- Designed to be used in the hosts that are publicly accessible from the Internet.
Private
- Not routable and can be used only in internal networks.
Example of public and private address
Legacy Classful Addressing
Class A - Designed to support extremely large networks with more than 16 million host addresses
Class B - Designed to support the needs of moderate to large size networks with more than 65,000 hosts.
Class C - This address space was intended to provide addresses for small networks with a maximum of 254 hosts.
