9. Type of IPv4 Address-Network Address

10. Type of IPv4 Address – Broadcast Address

11. Type of IPv4 Address – Host Address

12. Netmask (1)
To identify the bit for the same position in the IP address whether it is Network bit or Host bit
If the value of Netmask is
1 is the Network bit
0 is the Host bit
Example : IP address – Netmask
Network bit = the most 24 significant bits
Host bit = the least 8 significant bits

13. Netmask (2) Netmask can be represented as “prefix” (slash format)
The number of 1 is counted
Netmask is = /24
255 = (8 bits)
We can find Network Address (Network ID) from IP Address
Network Address = IP adresss & Netmask

14. Netmask (3) Logic AND (&) As a result, X & 0 – 0 X & 1 – X
0 & 0 – 0
0 & 1 – 0
1 & 0 – 0
1 & 1 – 1
As a result,
X & 0 – 0
X & 1 – X
Logic OR (|)
0 & 0 – 0
0 & 1 – 1
1 & 0 – 1
1 & 1 – 1
As a result,
X | 1 – 1
X | 0 – X

15. Network Address = IP address & Netmask
Example: IP address /28
Network Address = IP address & Netmask
&
Question: IP address = /22
Network ID = ?

16. Netmask (5)

17. Network Address & Broadcast Address
Network ID = IP address that all host bits are 0s
/24
Network ID =
Broadcast ID = IP address that all host bits are 1s
Broadcast ID =
