![]() ![]() I will try to add more and more practical examples and real life scenarios in IPv6 tutorial video series along with the theoretical explanation. This video series will serve as a IPv6 tutorial for beginners and will help as a quick reference for advanced users. Have a look at EUI 64 conversion from MAC address video for more details and rationale.IPv6-101 video series on will start with the basic introduction to IPv6 protocol. And you are done… it’s as simple as that. Toggle universal/local bit in the MAC address.Divide the MAC address into 2 equal parts and add FE:FF in between.The interface identifier of an IPv6 host address uses the IEEE EUI. The interface identifier is globally unique, similar to a 48-bit MAC address. Each group contains 4 hexadecimal numbers in the format X:X:X:X. The following command creates a link-local IPv6 address ( fe80:: prefix) from a MAC address: ipv6calc -action prefixmac2ipv6 -in prefix+mac -out ipv6addr fe80:: 00:21:5b:f7:25:1b. Here’s MAC to IP conversion process step by step: take the mac address: for example 52:74:f2:b1:a8:7f. The ipv6 address eui-64 command configures a global unicast address in EUI-64 format for an. This conversion process can be explained in two steps. If you want to create a whole IPv6 address from a MAC (and a given prefix), you could use the excellent ipv6calc tool by Peter Bieringer. ![]() ![]() I have also explained the rationale behind the method for converting MAC address to EUI 64 address. This video explains how to derive EUI 64 form from the MAC address. These days some machines implement random number generator for deriving lower 64 bits, but still EUI64 from MAC address is a very popular and easy to use method. The higher 64 bits are taken from the router prefix or for link local address these bytes are fixed. From the second thread, IPv6 Address Format with Interface ID and EUI-64, quoting Keith Barker - 'So the bottom line is that the bit, on or off, doesnt mean anything anymore, but at some historical point it probably did.' 4. With the help of the MAC address (which is globally unique) the interface derives lower 64bits of the address. For generating unique automatic address the machines generally use the MAC address. Description: One of the very interesting thing in IPv6 is its automatic addressing stuff. ![]()
