root@dlp:~ #

vi /usr/local/etc/namedb/primary/srv.world.lan

$TTL 86400
@   IN  SOA     dlp.srv.world. root.srv.world. (
        ;; any numerical values are OK for serial number
        ;; recommended : [YYYYMMDDnn] (update date + number)
        2023122001  ;Serial

        86400       ;Minimum TTL
)
        ;; define Name Server
        IN  NS      dlp.srv.world.
        ;; define Name Server's IP address
