Berhubung kali ini saya menjelaskan tentang IP
Addres Kelas C, saya memiliki tugas dari dosen saya berikut beberapa contoh
soal untuk menentukan Subnet dan Host Valid beserta cara penyelesaiannya.
Soal:
Tentukan Subnetnya dan Tentukan Host Validnya
1. 192.168.16.0 /27
2. 192.168.16.0 /28
3. 192.168.16.0 /29
4. 192.168.16.0 /30
5. 192.168.16.0 /25
Penyelesaian:
*192.168.16.0/27
