Why ssh work only in the same ip domain

By the way, is there any method to power down the Linux gracefully? I tried some commands like "power off", "shutdown", "halt" etc, but it shows that those commands are all not found. So the only choice for me to close the Linux is to pull up the power switch of the board. And this behavior of mine is a little bit rude because I may think that this behavior is not healthy for the running Linux.
Thanks~

So what is the principle behind the board connecting to the internet and is there any method to remove this "IP same" constrain?

192.168.0 is address of a network (aka subnet or LAN), 62 is address of a machine on that network. Machines on a same subnet can communicate directly. Machines on different subnets need a 3rd machine (aka gateway) to route (or relay) traffic between subnets. However, 192.168.xx is a special class of subnets, which are not "routable" by default. Anyway, this has nothing to do with the board or RISC-V. Your board is 100% ready for networking. "IP same" constrain is property of your network, and it is, probably, intentional.

I tried some commands like "power off", "shutdown", "halt"

These commands only available for superuser (aka root), use sudo to run the command:

sudo poweroff

Oh, I see. Thank you~
