# godyn

a simple server and client for dynamic dns updates.  

---

the server simply responds to http requests with your current ip address.

---

the client sends a http request to a defined server to get your current remote/wan ip adress and sends an update to your dyndns provider if it has changed.

**note:**  
godyn in client mode expects the return value from the remote/wan ip provider to be a single line which contains the ip address (same return value like godyn in server mode or `curl https://icanhazip.com`).

## run
