Title: Binary Lesson 6 Classful Subnetting


1
Binary Lesson 6Classful Subnetting
2
Slash Notation
  • Consider a class A address of 1.2.3.4
  • The network portion is the first octet
  • 1
  • This situation can be written
  • 1.2.3.4/8
  • The number after the / is the number of bits in
    the network portion

3
Subnet Mask
  • Consider a class A address of 1.2.3.4 /8 in
    binary
  • The subnet mask is 255.0.0.0
  • The network address is 1.0.0.0
  • In Binary
  • IP 00000001 00000010 00000011 00000100
  • Subnt Msk 11111111 00000000 00000000 00000000
  • Net Addr 00000001 00000000 00000000 00000000

4
AND
  • To find the network address, take a node's IP
    address and do this
  • If the Subnet mask bit is 1, keep the IP address
    bit
  • If the Subnet mask bit is 0, that bit changes to
    0
  • This is called a bitwise AND operation
  • IP 00000001 00000010 00000011 00000100
  • Subnt Msk 11111111 00000000 00000000 00000000
  • Net Addr 00000001 00000000 00000000 00000000

5
Class B
  • Class B address 147.144.1.212 /16
  • The subnet mask is 255.255.0.0
  • The network address is 147.144.0.0
  • In Binary
  • IP 10010011 10010000 00000001 11010100
  • Subnt Msk 11111111 11111111 00000000 00000000
  • Net Addr 10010011 10010000 00000000 00000000

6
Class C
  • Class C address 192.168.1.10 /24
  • The subnet mask is 255.255.255.0
  • The network address is 192.168.1.0
  • In Binary
  • IP 11000000 10101000 00000001 00001010
  • Subnt Msk 11111111 11111111 11111111 00000000
  • Net Addr 11000000 10101000 00000001 00000000

7
192.168.1.0 /25
  • You can split a class C in half with a /25
  • IP 192.168.1.10 /25
  • Subnet Mask 255.255.255.128
  • Network 192.168.1.0
  • IP 11000000 10101000 00000001 00001010
  • Subnt Msk 11111111 11111111 11111111 10000000
  • Net Addr 11000000 10101000 00000001 00000000
