  • EUI-64 IPv6: Why flip 7th bit of 1st byte - Cisco

    1) halving the mac address of device (MAC address have 48 bits) 2) Add FFFE (16 bits); hence 48 bits + 16 bits = Prefix ID Interface. 3) Finally reverses the seventh bit of the MAC address and copies the result to the block of the prfix ID Interface. Regards.

    2021-6-5 · In MAC address architecture, the 7th bit signifies whether the MAC address was universally or locally assigned. A value of 0 indicates the address is universally administered. For instance, the when IANA assigns an Organizationally Unique Identifier (OUI) to a NIC card vendor, the 7th bit will be 0, indicating the OUI was universally assigned.

  • What are IEEE EUI-64 based Global Unicast IPv6

    The 7 th bit represents the universal unique bit. A “built in” MAC address will always have this bit set to 0. When you change the MAC address this bit has to be set to 1. Normally people don’t change the MAC addresses of their interfaces which means that EUI-64 will change the 7 th bit from 0 to 1 most of the time. Here’s what it looks like:

    2012-2-16 · Sure, this isn’t actually a construct of the MAC to link-local IPv6 mechanism per se. Based on RFC 4291 section 2.5.6, a link-local IPv6 address is just “fe80” followed by 54 null bits followed by the Interface ID.The trick here is that the “Interface ID” is not the same thing as a mac address, I think it’s meant to be the new mac address but I have yet to see one in the wild.
