Contoh IPv6

ip v6 => version : traffic_class : flow_label : payload_length : Next Header : Hop_limit : source_addr : dest_addr

version : year e.g 2011,2006,2005
flow_label :
Aggregatable Global
Unicast Address        001       2xxx or 3xxx

Link Local Unicast 1111 1110 10  FE80::/10
Address

Unique Local Unicast 1111 1100 FC00::/7
Address 1111 1101 FC00::/8(registry) ,FD00::/8 (no registry)

Multicast Address   1111 1111  FF00::/8


==> jadi di link local
flow label menampung 10 bit ambil dari flow_label di atas
e.g. 1111 1110 10  FE80::/10 (memuat 10 bits) tinggal 54 bits dan sisanya sekitar 64 bit untuk
interface ID

lalu untuk unique local
1111 1100 FC00::/7 + globalID (40 bits) + subnet ID (16 bits) + sisa (interface ID)


==> multicast 1111 1111  FF00::/8
multicast(addr) + 4bit(lifetime yakni 0 untuk permanen dan 1 untuk sementara) + 4bit scope
(1 => Node, 2 => Links , 5 => site, 8 => organisation, E => global
sedikit pengetahuan tentangmulticast addr
Addr Scope Meaning
FF01::1   Node-Local   All Nodes
FF02::1 Link-Local   All Nodes
FF01::2   Node-Local   All Routers
FF02::2   Link-Local All Routers
FF05::2   Site-Local All Routers
FF02::1:FFXX:XXXX  Link-Local  Solicited-Node

for example @ CCNA
NIC dengan mac 0007.50(5e.9460 )so IP addr nya  FE80::207:50FF:FE(5E:9460 )
global unicast 2006:1::1, subnet 2006:1::/64


==> Solicited-Node Multicast Address
Prefix (FFO2::1:FF:) : Interface ID : lower 24
advantages
2001:0db8:0000:130F:0000:0000:087C:140B
2001:0db8:0:130F::87C:140B


loopback IP
IPV4 = 127.0.0.1
IPV6 = 0:0:0:0:0:0:0:1=> ::1
