Dynamic DNS (DynDNS)
Dynamic DNS (DynDNS) or DDS is a service that assigns IP addresses to Internet domain names. It is a service that allows you to access your home computer from anywhere in the world.
DDNS serves a similar purpose to the Internet’s Domain Name System (DNS) in that DDNS allows anyone hosting a Web or FTP server to offer a public name to potential users.
Unlike DNS, which only works with static IP addresses, DDNS also supports dynamic (changing) IP addresses, such as those assigned by a DHCP server. This makes DDNS a good choice for home networks that normally receive dynamic public IP addresses from their ISP.
How does a Dynamic DNS (DynDNS) service work?
To use DDNS, simply sign up with a dynamic DNS provider and install their software on the host computer.
For example, if you have FTP software installed on your computer to turn that device into an FTP server, you will need to install the DDNS application on that computer.
The software monitors the dynamic IP address for changes. When the address changes (which will eventually be by definition), the software contacts the DDNS service to update your account with the new IP address.
