IPv6 Address : Alamat tanpa special prefix
Sumber: http://tldp.org/HOWTO/Linux+IPv6-HOWTO/x476.html
3.1.1. Localhost address
This is a special address for the loopback interface, similiar to IPv4 with its “127.0.0.1”. With IPv6, the localhost address is:
0000:0000:0000:0000:0000:0000:0000:0001
or compressed:
- 1
Packets with this address as source or destination should never leave the sending host. 3.1.2. Unspecified address
This is a special address like “any” or “0.0.0.0” in IPv4 . For IPv6 it's:
0000:0000:0000:0000:0000:0000:0000:0000
or:
These addresses are mostly used/seen in socket binding (to any IPv6 address) or routing tables.
Note: the unspecified address cannot be used as destination address. 3.1.3. IPv6 address with embedded IPv4 address
There are two addresses which contain an IPv4 address. 3.1.3.1. IPv4-mapped IPv6 address
IPv4-only IPv6-compatible addresses are sometimes used/shown for sockets created by an IPv6-enabled daemon, but only binding to an IPv4 address.
These addresses are defined with a special prefix of length 96 (a.b.c.d is the IPv4 address):
0:0:0:0:0:ffff:a.b.c.d/96
or in compressed format
- ffff:a.b.c.d/96
For example, the IPv4 address 1.2.3.4 looks like this:
- ffff:1.2.3.4
3.1.3.2. IPv4-compatible IPv6 address
Used for automatic tunneling (RFC 2893 / Transition Mechanisms for IPv6 Hosts and Routers), which is being replaced by 6to4 tunneling.
0:0:0:0:0:0:a.b.c.d/96
or in compressed format
- a.b.c.d/96
