first of all i figured path MTU and link MTU diversity out.

second here is other query

i have read link-local ,site local , multicast and their address structures...
therefore link local starts with 1111111010 ....... site-local 1111111011
and multicast starts with 1111111111 ..........

-----------**********however in some documents as examples it shows ip address
like aaaa : bbbb : cccc : dddd : eeee : ffff : gggg : hhhh ( 8 parts, each 16 bits) ******** ----------

--------****"what is the type" for the ip address i showed "last" ? (unicast , multicast....)
BECAUSE LAST ONE IS NOT LIKE THE OTHERS AS I WROTE DOWN!*****-----------

I'm not sure I understand what the question is.

Have a look here for a pretty good description of IPv6 addressing.

There are 3 types of IPv6 they are multicast, anycast and unicast.

Multicast
The packet is delivered to all the hosts.
Hex = FF00
Binary Prefix = 1111 1111 0000 0000


Anycast
The packet is delivered to the nearest device.


Global Unicast
The identifier of a single host.
Hex = 2000
Binary Prefix = 0010 0000 0000 0000

Site Local Unicast
Hex = FEC0
Binary Prefix = 1111 1110 1100 0000
(Think 10.0.x.x 172.16.x.x 192.168.x.x local network)

Local Link Unicast
Hex = FE80 + Modified form of your MAC address (See RFC 3927) 11-22-33-44-55-66 split in half and add FF-EE in the middle result is = 11-22-33-FF-FE-44-55-66
Binary Prefix = 1111 1110 1000 0000
(Think 169.254.x.x APIPA)

The Hex above just sits at the front of a full IPv6 address so...

FEC0:bbbb:cccc:dddd:eeee:ffff:1111:2222 = Site local Unicast

FF00:0000:0000:0000:0000:0000:0000:1000 = Multicast

Hope that helps

PS I know I've left in all the zero's that can be remove.
PPS I'm no expert so if anyone can see any errors please left me know.

 

i know what multicast anycast and unicast is ...

the thing i tried to tell is

link local starts with 1111111010 .
site-local 1111111011
multicast starts with 1111111111

BUT

for example

2001 : 0000 : 0000 : 0000 : 0000 : bd3e : 2a1b : 0000 IS NOT LIKE link-local , site local or multicast
what is the type for this?

 

It is a Global Unicast, as mentioned above, and also in the link I gave, which I presume you haven't read. The only thing not quite right with the above comment on it is that the prefix is 001 (binary), i.e. just 3 bits.
