# DynDNS with dedyn/deSEC (https://desec.io)

This is needed if you want to make services available from the Internet. This may also be needed to validate SSL-ACME-Challenges used by letsencrypt.
deSEC is my preferred DNS provider but there are others too.

Use at your own risk.

Please look first at the playbooks downloaded and run by the install.sh to understand whats going on and then decide if it is fine for you to run on your system.

You also should test this on an non-productive Test-System to fit your needs.
