e4 mDNS flood

The e4 in AP mode send's out a mDNS in-addr.arpa. request every 20th second. I'm not sure if these are only sent on the ethernet or also on the wireless side, currently I'm not able to capture network traffic on a wifi device in order to test that.

The requests are not only for associated WiFi clients, the requests are sent for all IP's seen on the local network.

Could this be stopped in the next firmware?

Hi, this mDNS in-addr.arpa. request is normal, it is used to indicate the local DNS, displaying the corresponding relations between the domain name of local devices and its IP address.

Good day.
