You have a computer that runs Windows 7.
You need to configure an application to connect to the computer by using the IPV6 loopback address.
Which address should you specify?

A.
::1

B.
12::1

C.
127.0.0.1

D.
fe80::f56f:56cb:a136:4184

Explanation:

Loopback address
The loopback address (0:0:0:0:0:0:0:1 or ::1) is used to identify a loopback interface, enabling a node to send
packets to itself. It is equivalent to the IPv4 loopback address of 127.0.0.1. Packets addressed to the loopback
address must never be sent on a link or forwarded by a router.
Link-Local
Link-local addresses always begin with FE80. With the 64-bit interface identifier, the prefix for link-local
addresses is always FE80::/64. An IPv6 router neverforwards link-local traffic beyond the link.
Nodes use link-local addresses when communicating with neighboring nodes on the same link. For example,
on a single-link IPv6 network with no router, hostsuse link-local addresses to communicate with otherhosts on
the link. Link-local addresses are equivalent to Automatic Private IP Addressing (APIPA) IPv4 addresses
autoconfigured on computers that are running Windows. APIPA addresses use the 169.254.0.0/16 prefix. The
scope of a link-local address is the local link.
A link-local address is required for Neighbor Discovery processes and is always automatically configured, even
in the absence of all other unicast addresses.
