First you need to install my repository
yum install http://mirror.de-labrusse.fr/NethServer/6/noarch/nethserver-stephdl-1.0.0-1.ns6.noarch.rpm
then you can install my module
yum install nethserver-ddclient --enablerepo=stephdl
you have a bundle of dyndns providers, some are free of charge, others are not. If you think that more providers could be added, please raise an issue in github and provide the dydns configuration (GG is your friend)
When your providers is not listed, you have custom fields to fill but in case of specific settings it is possible that it doesn't work → raise a bug
Please raise Issues on github
