DNS and DDNS are both protocols that are part of the TCP/IP suite. They are used to translate domain names into IP addresses and vice versa. However, they have some key differences that affect how they work and what they are used for.

DNS stands for Domain Name System. It is a global network of servers that store and distribute information about domain names and their corresponding IP addresses. For example, when you type www.google.com in your browser, your computer contacts a DNS server to find out the IP address of Google’s website. Then, your computer uses that IP address to connect to Google’s server and load the web page.

DNS is based on static records that are manually updated by the owners of the domain names. This means that if a website changes its IP address, its owner has to update the DNS record accordingly. Otherwise, the website will not be accessible by its domain name.

DDNS stands for Dynamic Domain Name System. It is a service that allows you to assign a fixed domain name to a device that has a changing IP address. For example, if you have a home computer or a network device that connects to the internet via a router, your ISP may assign you a dynamic IP address that changes every time you connect or disconnect. This makes it hard to access your device remotely without knowing its current IP address.

DDNS solves this problem by automatically updating the DNS record with the current IP address of your device. You need to register with a DDNS service under an available name (e.g. example.com) and install a software on your device that will communicate with the DDNS service. Then, you can access your device by using the domain name example.com, regardless of its IP address.

DDNS has many advantages. You can use it to:

• Access your home computer or network devices from anywhere in the world
• Host your own website, FTP server, or email server on your home network
• Set up a VPN server or remote desktop connection for secure and private access
• Use smart home devices or security cameras that require an internet connection
• Play online games or stream media with friends and family

To use DDNS, you need two things: a DDNS provider and a router or firewall configuration. A DDNS provider is a service that offers you a domain name and updates it with your IP address. There are many DDNS providers available, some of them are free and some of them are paid. You also need to configure your router or firewall to allow incoming connections to your device. You may need to set up port forwarding or enable UPnP for this.
