7.How is the representation of a link-local address in IPv6 different from a global unicast address, and what prefix is commonly associated with link-local addresses?
In the representation of the link-local address, we have a fe80::/10 network prefix, followed by an all zero 54 bit network id, and end with a 64 bit interface id. Hence they are often represented as : fe80::/64, whereas global unicast address are represented with prefix 2000::/3.
In the case of a link-local address, it is typically represented with the fe80::/64 network prefix. This consists of a fe80::/64 network prefix, followed by an all-zero 54-bit network ID, and ending with a 64-bit interface ID. As a result, link-local addresses are commonly expressed as fe80::/64, while global unicast addresses use the 2000::/3 prefix.
