IPv6



IPv6 addresses are written by using eightblocks of four hexadecimal digits.

2001:0DB8:3FA9:0000:0000:0000:00D3:9C5A

You can shorten an IPv6 address by eliminatingany leading zeroes in blocks.

Unicast IPv6 addresses are divided into two parts:a 64-bit network component and

a 64-bit host component.

The network component identifies a uniquesubnet, and the IANA assigns these numbers toISPs or large organizations.

The host component is typically either based onthe network adapter’s unique 48-bit MediaAccess Control (MAC) address or is randomlygenerated.



global addresses, link-local addresses,

unique local addresses



IPv6 global addresses (GAs) are the equivalentof public addresses in IPv4.



Link-local addresses (LLAs) are similar to Automatic Private IPAddressing (APIPA) addresses (169.254.0.0/16) in IPv4 in thatthey are self-configured, nonroutable addresses used only forcommunication on the local subnet.

an LLA remains assigned to an interface as a secondaryaddress even after a routable address is obtained for thatinterface.

LLAs always begin with “fe80”.



Unique local addresses (ULAs) are the IPv6 equivalent of

private addresses in IPv4 (10.0.0.0/8, 172.16.0.0/12, and192.168.0.0/16).

These addresses are routable between subnets on a privatenetwork but are not routable on the public Internet.

Intra-site Automatic Tunnel Addressing

Protocol ISATAP)

6to4



ISATAP is a tunneling protocol that allows an IPv6network to communicate with an IPv4 networkthrough an ISATAP router



6to4 is a protocol that tunnels IPv6 traffic over IPv4 traffic

through 6to4 routers. 6to4 clients have their router’s IPv4 address embedded in

their IPv6 address and do not require an IPv4 address.

6to4 is intended to be used on the Internet.

You can use 6to4 to connect to IPv6 portions of the Internet

through a 6to4 relay even if your intranet or your ISP supportsonly IPv4.
