as asked in the Andriod chat room.
At home I have a remote-access VNC server set up (running UltraVNC server). My current Android VNC app, called, funnily enough andriodVNC will only accept IP addresses to connect to. This is fine when using it inside the home, but as I want to access it from outside my external IP address is dynamic, so when I save the settings one day it may be different the next day.
I have a domain, home.example.co.uk that is set up for the web server also running on that machine. If I open the ports in my home router, how can I connect via the server hostname (home.example.co.uk:5900, or similar)? If it requires a new VNC client, so be it.
