IPv6 – Neighbor Discovery Protocol

Today my topic is Neighbor Discovery Protocol or NDP.

Similar to IPv4’s address resolution protocol (ARP), IPv6’s NDP uses ICMPv6 to discover each other on a local network. It is used to get the MAC/Link Layer addresses of available hosts, and the connection information of available routers. In this video, I will talk about Router Solicitation (RS), Router Advertisement (RA), neighbor solicitation (NS), neighbor advertisement (NA) and redirect message. ICMPv6 types are also discussed.

    Excellent video, great explanation, only one doubt
    You say ICMP works at link-layer, but I think it does at Internet layer, isn't it?

    my doubt is, in all that neighbor advertisemnt and discovery what is the role of the switch since switches are layer 2. or do we need special layer 3 switches?

    neighbor unreachability detection (NUDes) if you leave the network mafia you have to send nudes, so that you don't disclose network information, else they release your NUDES
    duplicate address detection (DAD) they can also release information about your affairs to your family lol
    mapping from an IP address to a physical address allows the mafia members to acquire businesses and land without resistance
    perform auto configuration for a device on the network by asigning an official post to every member of the mafia
    the NDP the Network mafia Demarcation Protection 😀

    Amazing video sir. Bit confused with the node solicited multicast addresses in the NS portion. Node A FF02::1:FF23:B578 and node B FF02::1:FECD:34EE, where node solicited multicast address prefix FF02::1:FF00:0000/104. Thank you

    This video is better than the ccna course definition of it they define in the frame "special multicast addresses" now i know why computers don't have to "read" the frame that's because of the ff02::1 all-node multicast group addresses. Thanks a lot

    Hi Sunny very informative stuff…
    I have one question in the neighbor solicitation when Host-A sends a request for MAC Address to Host-B why does it not use the global unicast or link-local address of the Host-B. Why does it use solicit node multicast of B, any specific reason? Please explain.

    Thank You.

    Hi sir, thanks for that vidos
    firstly. I have a question, when a host boots up, he sends message for all router using FF02::2, ok. My question is, for the host that want know the Neighbor in Neighbor Messagens, what adress they use FF02::2 or FF02::1, how that works ? Thanks for do a great job for
    community with this videos.

    So I really am trying to follow this, PLEASE HELP ME. I have found IPv6 Ethernet connections an f8oe or something random devices connecting to my WiFi and using ALOT of data?. I never looked before and I decided to log into my Comcast account today to see why the bill was weird. Turns out I’ve been being charged 100$ extra a month because we go over the data limit.. but idk HOW and I’m thinking.. does this basically mean one of my neighbors is a total A hole and is having me pay for data that they are secretly using? Or even worse is it possible they can go through my personal devices photos and videos and private stuff as well? Please please help and tell me HOW to stop this if that’s what’s happening. Please
