dhcp.leases file, it calls autodns-dhcp_ddns whenever there are
changes, so that the changes are updated on the dns server and also
settled on the dhcp configuration. Also, it reloads dhcp server

from the cron as stated on the cron file for the package, however it
can also be called by hand whenever the administrator may want to.
