A Correct answer
Explanation

In IPv6, the 128-bit address is divided into two 64-bit parts: the network prefix (first 64 bits) and the interface identifier (last 64 bits). The interface identifier uniquely identifies a network interface, similar to a MAC address, and is often derived from it using EUI-64 format. 'Path of network', 'Prefix of network', and 'Subnet' refer to the first 64 bits or portions thereof.
