I see you are following the KB article on [How to connect to Denodo from Python - a starter for Data Scientists](https://community.denodo.com/kb/view/document/How%20to%20connect%20to%20Denodo%20from%20Python%20-%20a%20starter%20for%20Data%20Scientists?tag=ODBC+driver). In this, the denodoserver_name is the name of your machine where the VDP Server is installed. If you do not have a SYSTEM NAME and you use the IP to connect to the VDP Server from any client like VDP Administration tool, you can definitely use the same IP Address over here as well.
Additionally, if you are using **odbcdriver** parameter, then its a DSN less connection. Therefore, after downloading the driver, you would need to install the driver in your system first and then you can just provide the name of the driver installed in this parameter to use it in your code. For example: In Windows OS, you can just go to ODBC Data sources from the Start menu and Click the Drivers tab to see all the drivers installed.
Hope this helps!
