WebApr 1, 2024 · The example output for the ipconfig command shows the IPv6 GUA being dynamically created using SLAAC and the EUI-64 process. An easy way to identify that an address was probably created using EUI-64 is the fffe located in the middle of the interface ID. The advantage of EUI-64 is that the Ethernet MAC address can be used to determine … WebThe EUI-64 is that format. With the EUI-64 format, the configuration of the interface ID takes place locally by the host in order to make it globally unique. The host requires already known and a globally unique piece of information. The piece of information must not exceed beyond 64 bits because by definition EUI-64 needs a 64-bit interface ID ...
WebAug 31, 2024 · EUI-64 is one of two methods used to auto-generate Interface ID part of IPv6 address. It is highly recommended not using this method, because it can be easily exploited in many different ways, for example, websites and apps associating different IPv6 addresses to a particular device or user. WebHere are the rules that a router uses to create the interface ID: 1. Split the MAC address in two halves (6 hex digits each). 2. Insert FFFE in between the two, making the interface ID. 3. Invert the seventh bit of the interface ID. For example, if the MAC address of a nework card is 00:BB:CC:DD:11:22, the interface ID would be 02BBCCFFFEDD1122.
