The IEEE policy is to discourage new uses of 48-bit identifiers in favor of the EUI-64 system. Source: Internet
The process involves filling the address space with prefix bits left-justified to the most-significant bit, and filling the MAC address in EUI-64 format into the least-significant bits. Source: Internet
In addition, the EUI-64 numbering system encompasses both MAC-48 and EUI-48 identifiers by a simple translation mechanism. Source: Internet
MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64. Source: Internet
The IEEE claims trademarks on the names EUI-48 citation and EUI-64, citation in which EUI is an abbreviation for Extended Unique Identifier. Source: Internet
To convert a MAC-48 into an EUI-64, copy the OUI, append the two octets FF-FF and then copy the organization-specified extension identifier. Source: Internet
