Dynamic Domain Name Service Switch
Simple Python HTTP server that reads a callers IP and saves it to a folder.
An NSS module on the host will then use these saved IPs to connect them with a specified hostname, ending with .ddnss
as TLD.
The endpoint is secured using Basic HTTP Auth.
Use a proxy (e.g. nginx) for SSL connections.
Server example for docker-compose, see docker-compose.yaml
Nginx client example for docker-compose docker-compose-nginx-ddnss.yaml
