Address Resolution
Purpose is to determine the link level-address of a destination given only its IP address.
Consists of sending a Neighbor Solicitation message and waiting for a reply.
- All nodes start up by joining the all-nodes multicast address and the solicited node multicast address
- Solicited node address is taking the 96 bit prefix FF02:0:0:0:0:1 and place the low order 32 bits of the destination IP address to this
- This allows for a range of FF02:1:0:0 through FF02:1:FFFF:FFFF
- The full target address is embedded in the ICMP packet
