IPv6 ADDRESSING

IPv6 has 128-bit addresses. A 128-bit address adds network prefix and host suffix. An benefit of IPv6 addressing is that there is address classes i.e. prefix/suffix boundary may fall anywhere.

 

 Following are special kinds of addresses, IPv6 provides:

 

Unicast: It is used for single receiver computer.

Multicast: It is used for multiple receivers; possibly not at similar site.

Cluster: This kind of address is used for collection of devices with same prefix, datagram is send to one out of cluster.

 

IPv6 ADDRESS NOTATION:

128-bit addresses unwidely in dotted decimal; needs 16 numbers:

 

105.220.136.100.255.255.255.255.0.0.18.128.140.10.255.255

 

Groups of 16-bit numbers in hex differentiate by colons - colon hexadecimal.

 

69DC: 8864:FFFF: FFFF: 0:1280:8C0A:FFFF

 

Zero-compression - series of zeroes shown by two colons

 

FF0C: 0:0:0:0:0:0:B1

FF0C::B1

 

IPv6 address with 96 leading zeros is stopped to hold an IPv4 address.
