IP ADDRESSING

Terbahagi kepada 3 kelas iaitu :

• CLASS A
• CLASS B
• CLASS C

CLASS A ----- CLASS A FOR LAN

• IP ADDRESS : 10.X.X.X
• SUBNETMASK : 255.255.0.0

CLASS C ----- LOCAL NETWORK

• CONTOH : 192.168.0.X ------------- ( X = 1-254 )
• SUBNETMASK : 255.255.255.0

CONTOH :

• SUBNETMASK IP ADDRESS
  255.255.255.0 ------------- 10.1.1.10
  ------------- 10.1.1.25
  255.255.0.0 ------------- 10.1.1.10
  ------------- 10.1..5.20
  ------------- 10.1.1.25
  255.0.0.0 ------------- 10.1.1.10
  ------------- 10.1.5.20
  ------------- 10.2.1.15
  ------------- 10.1.1.25
