You may connect to the Domain using this telnetable address

dragons-domain.org port 8888

Basically DD will accept connections from the cheapest nastiest telnet client you can find, but the most popular clients in use by our players are Mudlet for Windows, OS X, Ubuntu, Linux, and ChromeOS, tinyfugue, Tintin, and Savitar.
We particularly recommend Mudlet, as we have built a graphical user interface (GUI) for this platform that will auto-download and install if you connect with it!

See you on there!
