Question

A global unicast address ( GUA ) is a unicast address that is globally unique and can be routed globally. RFC 4291 specifies to be reserved as global unicast address space to be allocated by the IANA.

Options:

FEC0::1
FF02::1
2001:0db8:abcd:0012::1
FD00::1

Answer 1

A global unicast address (GUA) is a globally unique and routable unicast address used in IPv6 networks. It is allocated by IANA as specified in RFC 4291.

Step-by-step explanation:

A global unicast address (GUA) is a unicast address that is globally unique and can be routed globally. It is reserved as global unicast address space to be allocated by the IANA as specified in RFC 4291. Global unicast addresses are used in IPv6 networks.

For example, the address 2001:0db8:abcd:0012::1 is a global unicast address. It is globally unique and can be routed globally.

On the other hand, FEC0::1 and FF02::1 are not global unicast addresses. FEC0::1 is an IPv6 site-local unicast address, and FF02::1 is an IPv6 link-local unicast address.
