So, I'm confused, now? How does the Flows know what name to put instead of
IP? Does it use the PTR record in the DNS?

IM Flows consists of two pieces, a server and a client. The server code installs and runs on the InterMapper Server and collects netflow packets. The server piece doesn't bother with names at all.

The client code is a plugin that runs within the InterMapper GUI on the client computer. The client code runs a query against the flows server and displays the results. The results do not include any names, so the client resolves these using DNS PTR records.

The client uses the system-provided API's to resolve PTR records in DNS. On Windows, the DNS api's will substitute the WINS host name if you query the name of your own host.

I hope this helps.
