OpenDacs : Getting user IP for Position usage and actions needed on multiple positions

Hello,

I'm using OpenDACS .NET, and the use case is basically end-user authentication and permissions check for the application.

I'd like to know how important is that the Position IP Address is correct and valid to DACS and Refinitiv? Since this is an company internal application.

I'm using SignalR to stream data, and using this command to get the user Ip:
Context.GetHttpContext()?.Connection.RemoteIpAddress?.MapToIPv4().ToString()
Being "Context" part of the class HubCallerContext
Is this valid?

Also, regarding multiple positions, is this handled by DACS itself, or any action needed in the OpenDACS side? I got a bit confused.

If a user logs in with another ip address, does the previous one get logged out or is He not allowed to log in twice? In case that a maximum of 1 simultaneous user is set.

And if a user joins multiple times with the same ip address, is this allowed and compliant? Since it would be the same credentials.

Best Regards,
Jose Cruz

Hi @jose.cruz,

The answer to your question will depend on your intended use for this information. Typically, DACS is used for generating exchange reports for billing purposes. In this case, the IP address of the user is not as important as the correct data entitlements. However in the internal applications, the market data administrators might be interested in limiting access to certain IP address only. Single or multiple login for a same user is also configured by the DACS administrator.
