Android上で Free VPN Grass を素早く検証する
Ensuring your VPN truly protects your Android data is essential for privacy and security. This guide shows step-by-step how to verify Free VPN Grass is active, leak-proof, and configured correctly on your Android device.
To verify Free VPN Grass is protecting your data on Android, confirm the app shows an active secured connection, check your public IP and DNS via independent websites, run WebRTC and DNS leak tests, verify permissions and the kill-switch, and retest after reconnecting or network changes.
Free VPN Grass がデータを保護していることを確認する方法
Follow these explicit steps to confirm Free VPN Grass secures your Android traffic. Each step includes tools to validate the protection and what to do if a test fails.
-
Open the Free VPN Grass app and connect to a server. Wait for the app’s connected indicator (usually a “Connected” label or shield icon) and ensure the connection duration counter increments.
-
Use a website like whatismyip.com or ipleak.net before and after connecting to confirm your public IP and location reflect the VPN server, not your mobile carrier or home IP.
-
Visit DNS leak test tools and WebRTC leak checkers (e.g., dnsleaktest.com and browserleaks.com/webrtc) to verify DNS requests and real-time communication APIs do not expose your real IP.
-
If Free VPN Grass has a kill-switch, enable it and then toggle Wi‑Fi/cellular or force-stop the app to see if traffic is blocked when the VPN disconnects. Successful protection means no network access without the VPN.
-
Open Android settings, confirm Free VPN Grass has necessary permissions (VPN permission, network access), and exclude the app from aggressive battery optimization to avoid unexpected disconnects.
-
Run a speed test (Speedtest by Ookla) while connected to measure latency and throughput. Also check location-restricted apps or websites to confirm access reflects the VPN server region.
-
Switch between Wi‑Fi and mobile data, or move locations. Repeat IP/DNS/WebRTC checks after each change to ensure protection persists.
接続状況とアプリの表示を確認する
Start with the visible cues inside the Free VPN Grass app and Android system indicators:
- アプリの状態: 「接続済み」ラベル、サーバー名、および接続タイマー。
- Android システム: 接続中はステータスバーに VPN の鍵アイコンまたはロックアイコンが表示される。
- 通知: アクティブな VPN 通知が誤って切断されるのを防ぐ。
If the app shows connected but the Android status bar has no VPN icon, reopen the app and reconnect. Persistent mismatches suggest the VPN tunnel didn’t establish properly.
IP、DNS、および WebRTC のリークをテストする
Leak tests are central to verifying protection. Perform all three tests listed below.
- IP address check:
Visit an IP-checking site to confirm the displayed IP matches the VPN server location. If it shows your ISP IP, the VPN is not routing traffic.
- DNS leak test:
Use dnsleaktest.com or ipleak.net. The detected DNS servers should belong to the VPN provider or show the VPN’s network, not your ISP.
- WebRTC leak test:
On Android browsers, visit browserleaks.com/webrtc. Ensure no local (private) or public ISP IP addresses appear in the report.
Tip: Use an incognito browser session for tests to avoid cached location data and logged-in accounts influencing results.
アプリの権限と Android 設定を確認する
Permissions and system settings can affect the VPN’s reliability. Check these areas:
- VPN権限: アプリはAndroidのVPN権限を要求し、保持する必要があります（最初に接続したときに付与されます）。
- ネットワーク権限: モバイルデータとWi‑Fiへのアクセスが許可されていることを確認します。
- バッテリ最適化: OS がアプリを停止しないように Free VPN Grass をバッテリ最適化の対象外にします。
- 自動起動とバックグラウンドデータ: 画面がオフでもトンネルを維持できるよう、アプリがバックグラウンドで動作できるようにします。
確認手順: Settings → Apps → Free VPN Grass → Permissions & Battery. 途切れない保護を確保するために必要に応じて設定を調整してください。
パフォーマンス、速度テスト、および実用的な確認
Security is critical, but usability matters too. Confirm the VPN maintains usable speeds and correct routing:
- Use Speedtest to measure ping, download, and upload with and without the VPN.
- Test content access: Open geo-restricted sites or apps to confirm they see the VPN server region.
- Monitor app stability: Note how long the connection remains active during normal use and after screen lock.
If speeds are unusually slow, switch Free VPN Grass servers or try a different protocol (if available) to find a balance between speed and security.
VPN 保護の自動化と監視
Regular checks help catch issues before they affect privacy. Consider these automation and monitoring tips:
- Enable notifications and auto-reconnect in Free VPN Grass settings, if available.
- Use a simple monitoring app or script on a secondary device to ping an external server; if pings reveal your real IP, you’ll know the VPN dropped.
- Schedule periodic manual checks (weekly IP/DNS leak tests) or after system updates that may change network behavior.
Pro tip: Keep Free VPN Grass updated via Google Play to receive security patches and reliability improvements.
クイック比較: 安全状態 vs 不安全状態
Use this table to quickly interpret test results and what they mean for your privacy.
| Check | Secure (expected) | Insecure (action needed) |
|---|---|---|
| Public IP | Shows VPN server IP/location | Shows ISP/home IP — reconnect or change server |
| DNS | DNS servers from VPN or unknown (encrypted) | ISP DNS listed — enable DNS leak protection or use secure DNS |
| WebRTC | No local or ISP IP exposed | Local/ISP IP visible — block WebRTC in browser or use browser with WebRTC protection |
| Kill-switch | Network blocked when VPN disconnects | Traffic continues after disconnect — enable kill-switch |
| App icon/status | App shows “Connected” and Android VPN icon present | No icon or incorrect status — reconnect and check permissions |
よくある質問
How do I know Free VPN Grass is actually encrypting my traffic?
Check that Free VPN Grass shows an active connection and then run an IP and DNS leak test. Encryption can’t be visually inspected, but a changed public IP and VPN DNS servers indicate your traffic is routed through the VPN tunnel and protected by its encryption.
What is a DNS leak and how can I test for it?
A DNS leak occurs when DNS requests bypass the VPN and use your ISP’s servers. Test at dnsleaktest.com or ipleak.net while connected; if the listed DNS servers belong to your ISP, enable DNS leak protection or switch DNS settings in the app.
Why does my Android show no VPN icon even when connected?
This can happen if Android’s notification settings or the app’s background permissions are restricted. Ensure Free VPN Grass is allowed to run in background and that VPN notifications aren’t suppressed in Android settings, then reconnect the VPN.
Can apps bypass the VPN on Android?
Some Android setups allow split tunneling or per-app VPN exceptions. Check Free VPN Grass settings for split tunneling options. If an app is excluded, its traffic may bypass the VPN. Remove exclusions to ensure all app traffic is protected.
How often should I re-test my VPN connection?
Re-test after major Android updates, network changes (Wi‑Fi to cellular), or if you notice unusual behavior. For routine assurance, run quick IP/DNS checks weekly or whenever you connect to public Wi‑Fi to confirm protection.
結論
Verifying your VPN is protecting your Android data is a combination of visual checks, leak tests, permission reviews, and occasional speed checks. By following the steps above, you can confidently confirm Free VPN Grass is routing and protecting your traffic.
