So, the interface ID will be 02BB:CCFF:FEDD:1122. Next, the router will insert FFFE in the middle of the address listed above: Here’s the conversion process step by step: take the mac address: for example 52:74:f2:b1:a8:7f.

A mac address is 48 bits, an IPv6 address is 128 bits. This will result in the following hexadecimal address: This link-local IPv6 is infered from the NIC’s mac address. Well, the router will first flip the seventh bit from 0 to 1. Invert the seventh bit of the interface ID.įor example, if the MAC address of a nework card is 00:BB:CC:DD:11:22, the interface ID would be 02BBCCFFFEDD1122. Do you need to convert a MAC address to different formats Use the MAC Address Converter tool from, a leading cloud hosting provider. The IPv6 to IPv4 calculator processes your request and provides you with a converted IPv4 address. Click on the 'Convert IPv6 to IPv4' button. Insert FFFE in between the two, making the interface ID.ģ. Suppose you enter an IPv6 address 0:0:0:0:0:ffff:0370:7334. Split the MAC address in two halves (6 hex digits each).Ģ. The link-local address is not used as a destination address of any of the host’s off-net packets, but rather, is just a way for the host to learn the MAC address of the next-hop router that will forward the host’s IPv6 packets onward to the destination address. Here are the rules that a router uses to create the interface ID:ġ. The interface ID created this way is known as the modified extended unique identifier 64 (EUI-64). Contribute to AddoSolutions/mac2ll development by creating an account on GitHub. Also, the 7th bit in the first byte is flipped to a binary 1. IPv6 is enabled, link-local address is FE80::C 0 00:1FFF:FE20:0. R1(config-if) do show ipv6 interface FastEthernet 0/0 i FE80.

An interface ID is created by inserting the hex number FFFE in the middle of the MAC address of the network card. IPv6 is enabled, link-local address is FE80::C 2 00:1FFF:FE20:0. 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.The second part of an IPv6 unicast address (used to identify a host’s network interface) is usually a 64-bit interface identifier.
