CCNP - ENTERPRISE - IPv6 - IP address types

The following is a list of IPv6 address types. The high order bits are displayed and their function:

i) 001 = Global - 200
ii) 1111 1111 = Multicast - FF
iii) 1111 1110 11 = Site Local - FEC0
iv) 1111 1110 10 = Link Local - FE80
v) ::X:X:X:X = IPv4 compatible address, where the first 96 bits are set to 0 (hence the ::) and the remaining 32 bits are converted to hex from the IPv4 address

Other addresses include:
::1 or 0:0:0:0:0:0:0:1 = Loopback
::/128 = unspecified address which is essentially the DFG for IPv6, all the bits are set to 0.
IPv6 private addresses start - 1111 1110 1 - therefore both site local and link local are private

  1. An Internet Protocol address (IP address) is a numerical label assigned to each connection.The computer uses this to establish the connection.Two versions of the IP are in use: IP Version 4 and IP Version 6.In IPv4 an address consists of 32 bits and the IP v6 uses from 32 to 128 bits.I have a IPv4 when I checked through Ip-details.com
