More input options

NETWORK & DNS

DNS, live traffic and internet speed

Additional Android network tools help you understand your connection. These are separate from Windows Guardian.

DNS protection options

See the active DNS setting and follow the available steps to use a filtering provider, such as Cloudflare or AdGuard. Your device must apply the setting; the DNS service performs the filtering.

Live network traffic

Check your phone’s current incoming and outgoing traffic, shown separately in Mb/s while the network view is open. This is not your mobile base station’s maximum capacity.

Internet speed test

Run a connection test to measure download speed, upload speed and latency to a test service. Results vary with Wi-Fi, mobile coverage and network congestion.

The DNS and speed tools shown here depend on your installed Android app version and device settings. Link Guard does not inspect every connection or provide continuous background blocking.
