how to convert mac address to ip6 address

You can convert IPv4 addresses to IPv6 and you can convert some IPv6 addresses into IPv4. So, the interface ID is now 02BB:CCFF:FEDD:1122.Īnother example, this time with the MAC address of 00000C432A35.ġ. Our IPv4/IPv6 converter is bidirectional. Next, we need to insert FFFE in the middle of the address listed above: hex 02BBCC FFFEDD1122 Now we have this address in hex: hex 02BBCCDD1122 Well, first we need to flip the seventh bit from 0 to 1. Remember that MAC addresses are used at layer 2 and IP is layer 3. When using stateless address autoconfiguration, you only need an IPv6. When this is done, the interface ID is commonly called the modified extended unique identifier 64 (EUI-64).įor example, if the MAC address of a network card is 00:BB:CC:DD:11:22 the interface ID would be 02BBCCFFFEDD1122. Converting MAC addresses into IPv6 interface IDs reduces the configuration workload. Also, the 7th Bit in the first byte is flipped to a binary 1 (if the 7th bit is set to 0 it means that the MAC address is a burned-in MAC address). A 64-bit interface ID is created by inserting the hex value of FFFE in the middle of the MAC address of the network card.

The second part of an IPv6 unicast or anycast address is typically a 64-bit interface identifier used to identify a host’s network interface.
