Subnet ID

Here you set the subnet ID that is to be combined with the prefix issued by the provider.

If the provider assigns the prefix "2001:db8:a::/48", for example, and you assign the subnet ID "0001" (or "1" for short), then the router advertisement on this interface is given the prefix "2001:db8:a:0001::/64".

The maximum subnet length with a 48-bit long, delegated prefix is ​​16 bits (65,536 subnets of "0000" to "FFFF"). With a delegated prefix of "/56", the maximum subnet length is 8 bits (256 subnets of "00" to "FF").

Note: In general, the subnet ID "0" is used when the WAN IPv6 address is compiled automatically. For this reason you should start with "1" when assigning subnet IDs for LANs.
