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 192.168.10.10 Netmask-
    255.255.255.0
  • 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 255.255.255.0 /24
  • 255 1111 1111 (8 bits)
  • We can find Network Address (Network ID) from IP
    Address
  • Network Address IP adresss Netmask

14
Netmask (3)
  • Logic AND ()
  • 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
Netmask (4)
  • Example IP address 192.168.10.20 /28
  • Network Address IP address Netmask
  • 192.168.10.20 255.255.255.240
  • 11000000 .10101000.00001010.00010100
  • 11111111. 11111111.11111111.11110000
  • 11000000 .10101000.00001010.00010000
  • Question IP address 192.168.10.20 /22
  • Network ID ?

16
Netmask (5)
17
Network Address Broadcast Address
  • Network ID IP address that all host bits are
    0s
  • 192.168.10.20/24
  • Network ID 192.168.10.0
  • Broadcast ID IP address that all host bits are
    1s
  • 192.168.10.20/24
  • Broadcast ID 192.168.10.255
