Welcome to the Dual Wiki! If you are interested in Dual but don't know where to start, you're in the right place.

What is Dual?

Dual is a free and open source project written in Java in March 2021. It is distributed under the GNU General Public License version 3 or later. This program helps you manage dynamic IP addresses using your hosts file.

Let's say you want to connect to a computer on a regular home network (with a dynamic IP address). In order to connect to it, you'd have to specify it's IP address every single time, and it would also change from time to time, since it's a dynamic IP address. Dual assists you by fetching the network IP address and then associating with a hostname of your choice.

What Dual is not

Right now, Dual gets the remote IP address by resolving a domain name associated with it. Dual does not detect IP address changes by itself yet.

Disclaimer

Dual is currently in an alpha version, meaning it's unstable. There are known issues (see Issues), and one of them does not preserve some of the existing comments on your hosts file. This program comes with ABSOLUTELY NO WARRANTY, please refer to the license for more details.
