IPv6 Solicited-Node Multicast
Compute the ff02::1:ffXX:XXXX solicited-node multicast address for an IPv6 address, and the 33:33 Ethernet multicast MAC it maps to.
This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

How it works
The solicited-node address is ff02:0:0:0:0:1:ff00::/104 with the low 24 bits of the target address appended. Neighbor Discovery uses it so an address query reaches only nodes sharing those 24 bits. The Ethernet multicast MAC is 33:33 followed by the low 32 bits of the multicast address. Multicast targets have no solicited-node address.
