It looks Mikrotik routers are doing a periodic DNS query to "upgrade.mikrotik.com" every ~10 seconds; it is the typical inactivity timer in eNB/gNB to place an 4G/5G modem in IDLE mode.
The result is the modem getting in IDLE a them back to CONNECTED every 10 seconds.
Any idea why there is this DNS query every 10 seconds? Any way to disable or configure it?
