Hi, i'm looking for some guidance regarding IPv6. This threw me loads last night. :-(
I understand the very basics regarding IPv6 and how the process of address assignment occurs with the unique local (FE), link local (FD) and how the MAC address is incorporated into the last 64 bits of the 128 bit address with the FFFE stuck between the MAC.
I know the link local address is used for the LAN communication but where does the global address come into play? Do each device on the LAN have 2 addresses?
I think it might be helpful if somebody would be kind enough to lay out a simple network with a few IPv6 addresses assigned so I can how things look.
Or an explanation would be great. ï
Thanks a lot!
your understanding is correct:
link local : confined on a link
unique local: can be routed as used as IPv4 RFC1918 private ip addresses cannot be used over the internet
unique local ipv6 addresses are defined in
Hope to help
