IP Address
• Terletak pada lapisan ke-2 TCP/IP• Bertindak sebagai identifikasi pada jaringan
komputer saat komunikasi data berlangsung• Terdiri dari 4 class:
– Class A: 255.0.0.0– Class B: 255.255.0.0– Class C: 255.255.255.0– Class D: untuk multi-casting– Class E: untuk keperluan khusus
• Saat ini menggunakan v4, dikembangkan v6 dengan alasan keterbatasan ‘stock’ nomor IP.
Subnet IP Address
• Misalkan:185.212.23.23/16Artinya: IP Address tersebut berada padasubnet-mask: 255.255.0.0255.255.0.0 = 11111111.11111111.0.0 16bit
• Misalkan:110.165.25.47/8Artinya: IP Address tersebut berada padasubnet-mask: 255.0.0.0255.0.0.0 = 11111111.0.0.0 8 bit
Subnetting IPv4
Konsep ini disebut Classless Inter-Domain Routing(CIDR)
Point-to-Point IPv4: Class A
125.162.24.30255.0.0.0
125.163.24.30255.0.0.0
Point-to-Point IPv4: Class B
190.162.24.30255.255.0.0
190.162.30.24255.255.0.0
Point-to-Point IPv4: Class C
196.162.24.20255.255.255.0
196.162.24.30255.255.255.0
Range Class IP Address
• Class A: 1 – 126• Class B: 128 – 191• Class C: 192 – 223
Hal utama dalam keterkaitanSubnetting IP Address
• Jumlah subnet• Jumlah host per subnet• Blok subnet• Alamat host dan broadcast valid
