I have connected my esp to a WiFi router. I know my ESP IP (WiFi.localIP();)
how can I figure out which port is my ESP listening to?

I already asked: What software are you running? post the code of the sketch you have uploaded. Also you dont just "listen for a port", you have to choose the right port for whatever functionality you are using. If your ESP is running a webserver, it will usually listen on port 80 - but only if you specifically told it to do so - if you included OTA update code, it will be listening on port 8266. It could be listening on many...or none. It is 100% dependent on what you are trying to make it do.

I suspect just by the nature of your question, if you have not written or uploaded code to perform a well-defined and specific task then it is probably not listening at all
