A great question I was asked in class was:
"If Neighbor Discovery processes have replaced ARP in ICMPv6, how do you look at the equivalent of the ARP cache?"
Here is the answer for Windows:
- Click START> RUN> and type cmd in the box to open Command Prompt. in your Windows environment.
- Type netsh at the command prompt, and then press ENTER.
- Now type interface ipv6, and then press ENTER.
- Lastly, type show neighbors, and then press ENTER.
Here is a sample output (though I was not connected to an IPv6 network):
Here is a Windows example output on Windows 10 connected to an IPv6 network (it is long):
For Linux, you can view IPv6 neighbors using the following command:
# ip -6 neighbor show
On a MAC, use the following:
Andrews-iMac:~ andrew$ ndp -a
Hope that helps!
