Why is iPad not visible in the list of devices connected to the router?

Question

network hardware

Good afternoon!
4 devices are connected to my wi-fi router (see screenshot). But in the list of clients, I only see 3. The fourth one is the iPad. Why is it not showing up? The hostname in its settings is set.

Answer 1

It seems to me that the essence lies in the fact that special protocols are used to discover devices on the network, for example, in your case it may be the open ONVIF protocol. Thanks to which you can see information about the device. But comrades from Apple rarely recognize open protocols and therefore use their own Bonjour, which your router most likely does not understand, or this protocol is disabled in it (yes, there are functions to disable this protocol)
. I can be wrong in the name of the protocols, but the essence is the same.
