This makes NDP as critical to IPv6 as ARP is to IPv4. In addition, thanks to NDP, the IPv6 protocol provides a new stateless address autoconfiguration service compared with the IPv4 protocol.
We then presented NDP's security flaws, as well as palliative but easy-to-implement protection solutions.
Finally, we describe the advanced and official protection solution for NDP, the SEND mechanism, and its limitations.
Currently, the SEND mechanism is little used for 2 main reasons:
it is not implemented in the majority of operating systems (e.g. Windows, MacOS);
