Port 3841

Hi, We have an enterprise environment and we are blocking port 3841. What I could notice is that all my IPads are trying to reach that port on 17.188.* network all the time !!

What is this port used for?

Every IPad is trying 3 times every 30 minutes!

I could notice also that many other ports are used to reach out to 17.188.* Apple network. What is that used for?

Port 3841
