I would like to update my IP at the DDNS service on twodns.de
Hardware is an Arduino Nano with w5100 EN module.

With curl this is easy to do.
But how do I send this line with client.print .. commands at the Arduino?

in one line:

curl -v -X PUT -u "email@email.de:12345abcdefg" -d '{"ip_address": "90.91.92.92"}' https://api.twodns.de/hosts/my.test.de

Username : email@email.de
API-Key : 12345abcdefg
90.91.92.92 : my local WAN IP
my.test.de : to be update

Example:

IPAddress server(192,168,2,10);
if (client.connect(server,80))
{
  client.println("PUT -u "email@email.de:123.........");  ???
}

Does anyone know the solution?

The standard ethernet library does not support a SSL (HTTPS port 443) connection. That may cause you a problem.

Oh, right. Thank you.
I need to find another solution.

According to your DDNS service, they have a port 80 (HTTP) url to update the IP.

This is for the manual login.
It must be entered then user name and password.
I don't know how you could program the Arduino
