Konsep subneting 2

<p>Subnetting : proses memecah belah blok IP dalam 1 network menjadi beberapa blok yg lebih kecil.<br /><br />-         Perhitungannya dg mengubah nilai biner subnetmask berdasarkan kelasnya<br />-         Tujuannya efisiensi penggunaan IP<br />-         Perhitungan subnetting menghasilkan 4 hal:<br /><br />1.       Jumlah subnet (jumlah network)<br />2.       Jumlah host persubnet<br />3.       Blok IP dalam 1 subnet<br />4.       Alamat network(subnet), alamt host, alamat broadcast yg valid<br /><br />-          Format subnetting ditulis dalam bentuk CIDR (classless inter domain routing)<br />Subnetmask/prefix network atau prefix subnetmask<br />Contoh : 192.168.1.0/24<br />Mencakup IP : 192.168.1.1 – 192.168.1.254<div class="MsoListParagraphCxSpMiddle" style="margin-bottom: .0001pt; margin-bottom: 0cm; mso-add-space: auto;">
