depois de seguir o manual em https://www.tombarbette.be/dynamic-dns-with-ovh/ temos que alterar o ficheiro /etc/default/ddclient de acordo com o seguinte:

# Configuration for ddclient scripts
# generated from debconf on dom ago 16 15:15:34 WEST 2020
#
# /etc/default/ddclient

# Set to "true" if ddclient should be run every time DHCP client ('dhclient'
# from package isc-dhcp-client) updates the systems IP address.
run_dhclient="false"
