convert mac address to ipv6 unique local unicast

There have been a few interesting comments on this post, I encourage you to read them if you want to learn more about this mechanism. prepend the link-local prefix: fe80::5074:f2ff:feb1:a87fĪ converter to do the same operation in reverse is available here.replace first octet with newly calculated one: 5074:f2ff:feb1:a87f.convert octet back to hexadecimal: 01010000 -> 50.convert the first octet from hexadecimal to binary: 52 -> 01010010.The syntax for identifying the zone is addresszoneID.

If you launch the ipconfig command, you can see the local-link and site-local addresses with their zone IDs. You can display the interface indexes on a host with the command 'netsh interface ipv6 show address levelverbose'.

reformat to IPv6 notation 5274:f2ff:feb1:a87f If a host is only connected to one site, this ID is always 1.

The MAC address is first separated into two 24-bits, with one being OUI (.

throw ff:fe in the middle: 52:74:f2: ff:fe:b1:a8:7f The IPv6 EUI-64 format address is obtained through the 48-bit MAC address.

take the mac address: for example 52:74:f2:b1:a8:7f.

An IPv6 device will use the MAC address of its. Here’s the conversion process step by step: EUI-64 (Extended Unique Identifier) is a method we can use to automatically configure IPv6 host addresses. This link-local IPv6 is infered from the NIC’s mac address.Ī mac address is 48 bits, an IPv6 address is 128 bits. Instead of getting an address via DHCP, a NIC will hop on the network with a link-local IPv6 address and with this will have to ability to do further configuration automatically (soliciting neighbors, router, et cetera). Link-local IPv6 addresses are used as part of the IPv6 network auto-configuration process.
