Incorrect Answers
Modified EUI-64 expands the 48-bit MAC and flips the U/L bit to form a 64-bit identifier. That is not sufficient here: Anycast uses one unicast-format address on multiple nodes and routing selects a reachable instance.
Single-mode fiber carries one principal propagation mode and supports long distances with appropriate optics. That is not sufficient here: Anycast uses one unicast-format address on multiple nodes and routing selects a reachable instance.
ULA is designed for local-scope addressing and is not advertised on the public internet. That is not sufficient here: Anycast uses one unicast-format address on multiple nodes and routing selects a reachable instance.
