What is the default IPv6 subnet prefix for a workstation?

IPv6 subnets are defined with a 64-bit network prefix. A workstation on a typical IPv6 LAN uses that 64-bit prefix for the network portion and the other 64 bits for the interface identifier, enabling stateless address autoconfiguration so devices can generate addresses themselves. A 128-bit prefix would give exactly one address, not a subnet. A 32-bit prefix is generally the global routing prefix assigned by an ISP to summarize routes, not the size of a local subnet. A 16-bit prefix isn’t the standard size used for end-host subnets in IPv6. So the common default for a workstation’s local subnet is a 64-bit prefix.
