Flags have 4 bits. The high-order flag is reserved, and must be initialized to 0.
T=0 indicates a permanently-assigned multicast address assigned by the Internet Assgined
Numbers Authority (IANA).
T=1 indicates a non-permanently-assigned multicast address.
Scope is a 4-bit value used to limit the scope of the multicast group. The values are as follows:

The solicited-node multicast address is a multicast group that corresponds to an IPv6 unicast or
anycast address. It is usually used for obtaining the Layer 2 link-layer addresses of neighboring
nodes within the local-link or applied in IPv6 Duplicate Address Detection. A node is required to
join the associated Solicited-Node multicast addresses for all unicast and anycast addresses that
have been configured for the node's interfaces.
