Link-local ipv6 address vs mac address

Please explain if you will. Feel free to email them at temp akrin. Since Win Vista Windows uses random ipv6 link local addresses. I got Please clarify.

Sharing technical and non technical bits and bytes

Just saying that everyone else identifies that bit as 7th , also it is more logical to start your counting from one rather than zero. After reading the suggestion and reply above my post, I understand and was relieved at the clarification. When counting bits you typically start from 0 Ben is right but you also start counting from the least significant bit.

Using the mac address B8: Then construct the IPv6 header and Neighbor Advertisement NA message header type,code, flags, and target address as if the tentative address is duplicated on another node. Hey Ben…recent changes appear to have broken this page…it processes the request, but no results are returned, just an empty doc. Is it nessesary to display scope id also if we want to display link local address somewhere?

I think they are wrong and if not please correct me by telling me why is it the 6th bit?

The 7nth bit is fliped. So, if in the mac address there is a 1 in the 7nth position of the 8 bits, then the 1 becomes a 0 and if it is a 0 instead of a 1, it becomes a 1 in the 7nth position. Thanks very much. Im a beginer to subnetting. Correct me if i am wrong. Im doing CCNA1 in cisco.

Many zeros do indeed equal to double column but this is for abbreviation purposes; meaning that fully writing each 0 is legal as well. Thanks for this … I was wondering if anyone has tried an excel formulae for this and if they would care to share.

IPv6-02 Lov'n the Link Local Address

Use this a lot martin. Bitnukl explained it in the comments: Per your suggestion, here it is. I hope this helps. Hey, can please put the Skript on github or something like that. But you should know, how eui interface ids are built and that with SLAAC stateless address auto configuration the link local address and one or more global unique unicast address es will normally be built from that eui interface id the link local address with prefix fe So what you wrote is the "common case" but not the only possibility.

Understanding IPv6: Link-Local ‘Magic’ (Part 2 of 7)

It is not necessary, that global unique unicast addresses start with 2. The currenty used address block for global unique unicast is So you were able to use a show command to include any addresses that were link local in order to find your MAC address on your own router? In other words, by doing a show command for fe I guess my next biggest question if anyone is able to answer- how would you utilize the solicited node multicast address?

Would you use the identifier of ff In your above example, if I was working on a router could I ping outside ff I suppose I'm trying to understand the point of doing that when I could just look at your link local address or global unicast address and get Layer 2 info from there. Am I way off on this? Bear with me haha- sorry!

I did a ping to the link local address of the DSL router before, to make sure, that t he DSL router is listed in the ipv6 neighbor table something like the equivalent of the arp table with ipv4. Then i did a "sh ipv6 neighbor" to list the known neighbors. The " inc fe I will not go into detail describing this here as there are many helpful links out on the web to explain the magic, including RFC Appendix A. Can this get complicated?

You tell me. Can you easily read the sniffer trace below and know who is who? Like most defaults, we can override them. For example, below I am assigning FE As you can see, this makes the sniffer trace much easier to read. This will become even more important, in my opinion, when we talk about RAs router advertisements in the future. There is no magic of course.
