Learn how to setup dynamic DNS in hostd with DuckDNS

DuckDNS is a free and reliable DDNS provider that offers a straightforward solution for associating a dynamic IP address with a domain name. It's important to note that DuckDNS only supports domains in the format of `*.duckdns.org`. In this guide, we will walk you through the process of configuring DDNS in hostd using DuckDNS, enabling you to maintain uninterrupted connectivity to your storage provider, even with a dynamic IP address.
