The IP header (IP Ver4) is added to higher-level data (as defined
in RFC791). This header con-tains a 32-bit IP address of the
destination node. Unfortunately, the standard 32-bit IP address
is not large enough to support the growth in nodes connecting
to the Internet. Thus a new standard, IP Version 6 (IP Ver6,
aka, IP, The Next Generation, or IPng), has been developed to
support a 128-bit address, as well as additional enhancements,
such as authentication and data encryption.

1. Outline the main advantages of IPv6 over IPv4:
2. RFC (Request For Comment) documents allow standards to be
set using material which is published as an RFC specification.
Several classic RFC's include RFC821/RFC822
(POP-3), and so on. Determine the RFC which relates to IPv6
Addressing Architecture and its authors:
3. From this RFC, outline the format of the address, and the
usage of the compressed format:
4. In IPv4 the loopback address is 127.0.0.1. What is the loopback
address in IPv6:
5. With IPv6, outline how multicast addresses are defined:
6. Identify a practical IPv6 network, and outline its architecture:
7. What is IPv6-in-IPv4 tunnelling, and how it is used in practical
