Introducing No-IP Dynamic Update Client (DUC) for Windows
---------------------------------------------------------
No-IP DUC is a program that monitors your IP address and
notifies No-IP.com's dynamic DNS system when it changes.
The client downloads the list of hosts that you have
added via No-IP's web interface. You then check the ones
you want updated to your computers/routers IP address.


Program Features
---------------
No-IP Dynamic Update Client (DUC) v2.x is a complete
re-write from v1.x. The following features were
designed to give you a better No-IP experience.

- Auto network configuration that makes setup faster.

- Easier to use. The client downloads all of the
hosts associated with your account. Simply check
the ones you want update.d

- Use encrypted data. Update requests are encrypted
to insure data integrity.

- Can be ran as a NT service. You do not have to log
on to your NT machine to have the client run.



INSTALLATION
------------
Run the self-extracting file ducsetup.exe to unzip
and install No-IP DUC. The installation wizard will
guide you through the install process.
