on windows how to detect all photons in network?

How to determine whether a IP address is of a photon?
any api available?

You could install Bonjour service (or similar) on your Windows machine and have all your Photons feature an mDNS service.

Or you run your own discovery scheme via multicast or broadcast TCP/UDP packets all Photons would reply to.
