IPv6 Addressing

Loopback Address

fe90::215:60ff:fe7a:adc0

then the corresponding solicited-node multicast address is

Loopback Address

The IPv6 loopback address is a link-local unicast address that enables a device to send traffic to itself for self-testing purposes. The loopback address does not have a physical interface assignment. If an IPv6 packet destined for the loopback address is received on a switch interface, it must be dropped. The IPv6 loopback address is never used as the source IPv6 address for any packet that is sent out of a device, and the switch drops any traffic it receives with a loopback address destination. An example use case is:

ProCurve# ping6 ::1

0000:0000:0000:0000:0000:0000:0000:0001 is alive, time = 1 ms
