oleh tanda titik setiap 8 bitnya. Tiap 8 bit ini disebut sebagai oktet. Bentuk
IP address dapat dituliskan sebagai berikut xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxx
Jadi IP address ini mempunyai range dari 00000000.00000000.00000000.00000000
sampai 11111111.11111111.11111111.11111111. Notasi IP address dengan bilangan
biner seperti ini susah untuk digunakan, sehingga sering ditulis dalam 4
bilangan desimal yang masing-masing dipisahkan oleh 4 buah titik yang lebih
dikenal dengan “notasi desimal bertitik”.</span></div>

versi 4 terdiri atas 4 oktet, nilai 1 oktet adalah 255. Karena ada 4 oktet maka
jumlah IP address yang tersedia adalah 255 x 255 x 255 x 255. IP address

dikelompokan dalam lima kelas, yaitu kelas A, B, C, D, dan E. Perbedaannya
terletak pada ukuran dan jumlah. IP address kelas A jaringan. IP address Kelas
B digunakan untuk jaringan berukuran besar dan sedang. IP address Kelas C untuk
pembagian jaringan yang banyak, namun masing-masing jaringan memiliki anggota
yang sedikit. IP address Kelas D dan E juga didefinisikan, tetapi tidak
digunakan dalam penggunaan normal, kelas D diperuntukan bagi jaringan
multicast, dan E untuk Eksperimental.</span><span style="font-family: "Times New Roman","serif"; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: "Times New Roman"; mso-fareast-language: IN;"></span></div>

<span style="font-family: "Times New Roman","serif"; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: "Times New Roman"; mso-fareast-language: IN;">Bahwa dalam jaringan WAN kita sering mengenal yang
namanya TCP/IP (Transmission Control Protocol/ Internet Protocol) sebagai
alamat sehingga pengiriman paket data dapat sampai ke alamat yang dituju (host
tujuan). TCP/IP membagi tugas masing-masingmulai dari penerimaan paket data
sampai pengiriman paket data dalam sistem sehingga jika terjadi permasalahan
dalam pengiriman paket data dapat dipecahkan dengan baik. Berdasarkan
pengiriman paket data routing dibedakan menjadi routing lansung dan routing
tidak langsung.</span></div>

atau mengupdate  rute statik ini secara manual ketika terjadi perubahan
topologi antar jaringan (internetwork).</span></div>
<div class="MsoNormal" style="line-height: normal; mso-margin-bottom-alt: auto; mso-margin-top-alt: auto; text-align: justify;">
<span style="font-family: "Times New Roman","serif"; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: "Times New Roman"; mso-fareast-language: IN;">Rute Dinamik – Rute secara Dinamik dipelajari oleh
router setelah seorang administrator mengkonfigurasi sebuah protokol routing
yang membantu menentukan rute. Tidak seperti rute Statik, pada rute Dinamik,
sekali seorang administrator jaringan mengaktifkan <b>rute Dinamik</b>, maka
rute akan diketahui dan diupdate secara otomatis oleh sebuah proses routing
ketika terjadi perubahan topologi jaringan yang diterima dari “internetwork” .</span></div>

suatu jaringan besar menjadi jaringan yang lebih kecil dengan cara mengorbankan
bit Host ID pada subnet mask untuk dijadikan Network ID baru. Subnetting
merupakan teknik memecah network menjadi beberapa subnetwork yang lebih kecil.
Subnetting hanya dapat dilakukan pada IP addres kelas A, IP Address kelas B dan
IP Address kelas C. Dengan subnetting akan menciptakan beberapa network
tambahan, tetapi mengurangi jumlah maksimum host yang ada dalam tiap network
tersebut.</span></div>

     lebih efisien. Jika internet terbatas oleh alamat-alamat di kelas A, B,
     dan C, tiap network akan memliki 254, 65.000, atau 16 juta IP address
     untuk host devicenya. Walaupun terdapat banyak network dengan jumlah host
     lebih dari 254, namun hanya sedikit network (kalau tidak mau dibilang ada)
     yang memiliki host sebanyak 65.000 atau 16 juta. Dan network yang memiliki
     lebih dari 254 device akan membutuhkan alokasi kelas B dan mungkin akan
     menghamburkan percuma sekitar 10 ribuan IP address.</span></li>

     memiliki ribuan host device, mengoperasikan semua device tersebut di dalam
     network ID yang sama akan memperlambat network. Cara TCP/IP bekerja
     mengatur agar semua komputer dengan network ID yang sama harus berada di
     physical network yang sama juga. Physical network memiliki domain
     broadcast yang sama, yang berarti sebuah medium network harus membawa
     semua traffic untuk network. Karena alasan kinerja, network biasanya
     disegmentasikan ke dalam domain broadcast yang lebih kecil – bahkan lebih
     kecil – dari Class C address.</span></li>

bingung membedakan antara subnet mask dengan IP address. Sebuah subnet mask
tidak mewakili sebuah <i>device</i> atau <i>network</i> di internet. Subnet
mask digunakan untuk menandakan bagian mana dari IP address yang digunakan
untuk menentukan network ID. Anda dapat langsung dengan mudah mengenali subnet
mask, karena octet pertama pasti 255, oleh karena itu 255 bukanlah octet yang
valid untuk IP address class.</span></div>

maksimal untuk network ID adalah 30 bit. Anda harus menyisakan sedikitnya 2 bit
untuk host ID, untuk mengizinkan paling tidak 2 host. Jika anda menggunakan
seluruh 32 bit untuk network ID, maka tidak akan tersisa untuk host ID. Ya,
pastilah nggak akan bisa. Menyisakan 1 bit juga tidak akan bisa. Hal itu
disebabkan sebuah host ID yang semuanya berisi angka 1 digunakan untuk
broadcast address dan semua 0 digunakan untuk mengacu kepada network itu
sendiri. Jadi, jika anda menggunakan 31 bit untuk network ID dan menyisakan
hanya 1 bit untuk host ID, (host ID 1 digunakan untuk broadcast address dan
host ID 0 adalah network itu sendiri) maka tidak akan ada ruang untuk host
sebenarnya. Makanya maximum network ID adalah 30 bit.</span></div>

dengan 192.168.1.2. Namun adakalanya ditulis dengan 192.168.1.2/24 artinya
bahwa IP address 192.168.1.2 dengan subnet mask 255.255.255.0. Lho kok bisa
seperti itu? Ya, /24 diambil dari penghitungan bahwa 24 bit subnet mask
diselubung dengan binari 1. Atau dengan kata lain, subnet masknya adalah:
11111111.11111111.11111111.00000000 (255.255.255.0). Konsep ini yang disebut
dengan CIDR (Classless Inter-Domain Routing) yang diperkenalkan pertama kali tahun
1992 oleh IEFT.</span></div>
