Mac address convert to ipv64/7/2024 ![]() ![]() A simple process can be used to determine the interface identifier from the 48-bit MAC address of a device like an Ethernet network interface card. Key Concept: The last 64 bits of IPv6 unicast addresses are used for interface identifiers, which are created in a special format called modified EUI-64. This gives us the modified EUI-64 interface ID. We change the universal/local bit (bit 7 from the left)įrom a zero to a one. We take the 24-bit local portion (the right-mostĢ4 bits of the Ethernet address) and put it into the right-most 24 bits Left-most 24 bits of the Ethernet address, and put them into the left-mostĢ4 bits of the interface ID. These can be converted to EUI-64Īnd then to modified EUI-64 form for creating an IPv6 interface ID.

To do so, just open the Adblock menu and select "Disable on ". If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. It's priced very economically and you can read all of it in a convenient format without ads. If you like The TCP/IP Guide, please consider the download version. And I have a family to support, just like you. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write.
