1 Introduction

If you’re looking to host a website or create a web server at home, a network-attached storage (NAS) device like Synology can be a great option. However, one challenge that you may face is that your home internet connection may not have a static IP address, which makes it difficult to access your server from the internet.

This is where Dynamic DNS (DDNS) comes in. DDNS is a service that allows you to assign a domain name to your home IP address, even if it changes frequently. In this blog post, we’ll show you how to use DDNS to create a web server on your Synology NAS.

You can use the free dynamic DNS service in some domain register, the below sample will use namecheap.com for create a free DDNS:
