subnet's significance is that it tells the user about the family of hosts being used, and interface id helps in differentiating the addresses since they are unique for each host. For average end user, they often cover half of the available bits in the address space(/64) , but there are instances where fewer are used.
The subnet in an IPv6 address, typically denoted by a /64 prefix, functions like a network identifier. It helps routers efficiently direct traffic to the correct network segment. Think of it as a zip code that directs mail to the right neighborhood.
The interface ID uniquely identifies a specific device within that network, similar to a house number within a neighborhood. This allows devices on the same subnet to communicate directly with each other.
For most home and small business networks, a /64 subnet is the common choice. As for the interface ID, it's often automatically assigned by the router using mechanisms DHCPv6, simplifying setup for users. However, manual configuration is also possible for specific needs.
