contoh kasus 1
IPv6 address 2001:12AD::/48
A. Network ID = 2001:12AD:0000 ==> 2001:12AD:0::/48
B. Rentang IP = 2001:12AD:0000:0:0000:0000:0000:0000 – 2001:12AD:0:FFFF:FFFF:FFFF:FFFF
C. Jumlah IP yang valid = 2^x = 2^80 = 1,2 x (10^24)
D. Jumlah Blok Subnet
Jumlah Blok Subnet 2^y
y=(prefix baru-prefix lama) = 50-48 = 2 >>> bit

IPv6 Address Type
1. UNICAST
2. MULTICAST
3. ANYCAST
Pengertian Unicast : Tipe addressing yang memungkinkan kita kita melakukan komunikasi dengan prinsip one to one
a. Global Unicast = public address ==> ip public
2000::/3
b. Link local address : komunikasi antar 2 host yang bertetangga dan tidak bisa di forward oleh router
FE80::/10
c. loopback address : ip loopback
::1
d. Unspecified address : tidak memiliki ip address v6
0:0:0:0:0:0:0
e. Unique Local Address : ip private / local
FC00::7
f. Embedded IPv4 address : alamat IPv6 yang menyimpan alamat IPv4 di dalam strukturnya,
sehingga mendukung interoperabilitas dan proses migrasi antara jaringan IPv4 dan IPv6.
contoh = ::FFFF:192.168.1.10
Pengertian multicast adalah teknik pengalamatan jaringan yang memungkinkan satu pengirim mengirim data ke sekelompok penerima dalam satu kali transmisi.
prefix FF00::/8
Anycast adalah teknik pengalamatan IP yang memungkinkan beberapa perangkat menggunakan alamat IP yang sama, tetapi paket hanya dikirim ke satu perangkat yang paling dekat atau memiliki rute terbaik.
