Randomized MAC defeats MAC-address-only child rules
How common it is: not a meaningful circumvention prevalence metric because randomized addressing is a normal Android feature. Google documents it for Android 10 and later and explicitly notes parental-control implicati…
Detection
The router shows a different/private MAC identity than the physical device identity, or a child device appears as a new client after identity rotation.
Fix (technical)
Google advises that parental controls using MAC identity account for both relevant MAC addresses. EN device path to inspect the addresses is documented under Wi-Fi/network details. Do not rely solely …
Fix (relational)
Randomized MAC is primarily a privacy mechanism. Its presence alone should not be framed as cheating.
Residual risk
Non-persistent randomization can create further address churn, and other devices may spoof or change link-layer identities.
