Since the migration from k1script to k1script1 was completed, we stopped k1script(Debian8).
Instead, k1script0 (Debian10) was copied from k1script1 and newly launched.
In the future, I plan to scripts that do not use Piconet from k1script1 will revert to k1script0.

The differences are as follows
k1script0: NOT connected to Piconet
k1script1: connected to Piconet

After the work, we rewrote the DNS from k1script to k1script0.
