Additionally, Does the same behavior apply to the send completion handler as well?

Thanks, I will go through the links provided.

@DTS Engineer Thanks I got the clarity regarding the ARC. I have a usecase where I get a Data Object in the CallBack I Register during the receive call. I want to pass the same Data Object to C++ without creating a Copy and ensuring that it remains valid until i am done with my operations in C++. Is there a way for that?

Thanks I will try this out, in mean time if you find where it's present in the active directory let me know.

Yeah its related to Active Directory. We used our host-name to identify a node in a network, similarly we also have network-name (local domain) assigned to a machine which doesn't varies, on the basis of network you are connected. This value helps form a full qualified name for the machine / device and can be used as an alternative to resolve to an IP Address to reach the machine / device or show it to the user as user relates more to names than IP Addresses.
