How EUI-64 Works in IPv6

EUI-64 is a method that converts hardware addresses into IPv6 addresses, simplifying IP address generation and enhancing network maintainability. It works by splitting a 48-bit hardware address into two 24-bit parts, inserting a special 16-bit code between them, and changing one bit, resulting in a 64-bit interface identifier. While EUI-64 supports autoconfiguration and simplifies troubleshooting, it raises privacy and security concerns as it links hardware and IPv6 addresses, potentially allowing device tracking and privacy leakage. Despite these concerns, EUI-64 is still used in some systems and is important for network administrators to understand.
