このガイドを信頼する理由
I have paid for Private Internet Access for three years across windows, linux and アンドロイド.
Every step below comes from my own install, not a press kit.
Most people install a VPN, click connect, and never open the settings again.
They use a vpn for streaming and ignore everything else it does.
That leaves half of what you paid for switched off.
This guide on how to use private internet access walks through every screen.
You will finish knowing which vpn type to pick and why.
プライベートインターネットアクセスチュートリアル
This How to Use Private Internet Access tutorial moves from your first vpn connection to router settings and leak testing.
プライベートインターネットアクセス
Hide your ip address on every device you own. PIA runs servers in 91 countries, keeps no logs, and never applies bandwidth caps. Plans start at $2.03 per month with a 30-day money-back guarantee.
プライベートインターネットアクセスを使い始める
Setup takes about three minutes on any operating system.
Here is my own walkthrough of the installation:
それでは、各ステップを詳しく見ていきましょう。
ステップ1：アカウントを作成する
Go to the Private Internet Access website and pick a plan.
PIA emails your pia username and password within a minute.
✓ チェックポイント: あなたの 受信トレイ holds a welcome email with login details.
Step 2: Download the VPN Software
PIA builds vpn apps for all major operating systems.
Choose the installer for windows, macOS, linux, android or iOS.
Run the installer and accept the driver prompt your operating system shows.
On a pc, the installer adds its own network adapter automatically.
On Ubuntu, Debian, Fedora or Linux Mint, run the .run file from your home folder.
✓ チェックポイント: The vpn app icon sits in your tray or app drawer.
Step 3: Log In and Connect
アプリを開いて、ユーザー名とパスワードを入力してください。
Press the big power button to connect to a server automatically.
Connecting usually takes about five seconds on a nearby vpn server.
✅ 完了: You are connected and ready for every feature below.
プライベートインターネットアクセスのログなしポリシーの使用方法
ログなしポリシー proves that no pia server keeps a record of your online traffic.
以下に、その使用方法をステップごとに説明します。
Step 1: Open the Privacy Settings
Launch the vpn app and click the gear icon.
Open the Privacy tab to see what pia stores about you.
Step 2: Read the Transparency Report
Click the report link to view PIA court records and audits.
これは以下のようなものです。
✓ チェックポイント: Nothing on the account page lists your visited sites or ip addresses.
Step 3: Turn On MACE
Toggle MACE to block ads and trackers at the DNS level.
✅ 結果: Your online traffic leaves no stored trace on the vpn service.
💡 プロのヒント: PIA uses open-source code, so anyone can audit the vpn client for hidden logging.
プライベートインターネットアクセス専用IPの使用方法
専用IP gives you a static ip address that nobody else shares.
以下に、その使用方法をステップごとに説明します。
Step 1: Buy the Add-On
Open your account dashboard and add a dedicated ip to your plan.
Step 2: Redeem the Token
Copy the token, then paste it into the Dedicated IP tab.

✓ チェックポイント: A new region with your own ip address appears in the list.
Step 3: Connect to That Region
Click the region to open the vpn connection on your reserved ip.
✅ 結果: Every session now uses the same new ip address instead of a shared pool.
💡 プロのヒント: A static ip address stops banking sites from flagging you as a bot each login.
Private Internet Access Antivirus の使い方
ウイルス対策 scans your device for malware while the vpn tunnel stays active.
以下に、その使用方法をステップごとに説明します。
ステップ1：プランにウイルス対策ソフトを追加する
Open the account page and enable the antivirus add-on.

VPNルーター covers every device on your network, including a TV or console.
以下に、その使用方法をステップごとに説明します。

Step 3: Assign Devices to the Tunnel

✅ 結果: Every device pulling an address from your dhcp server now rides the vpn tunnel.
💡 プロのヒント: PPTP connects faster but protects less, so pick オープンVPN as your vpn type.

プライバシー保護 keeps your real internet access hidden even when the tunnel drops.
以下に、その使用方法をステップごとに説明します。

Open Settings and switch the kill switch to Advanced.

✅ 結果: Your internet is blocked instead of exposed whenever the vpn connection fails.
💡 プロのヒント: Set the protocol to WireGuard for speed and OpenVPN when you want proven security.
How to Use Private Internet Access DNS Leak Tester

プライベートインターネットアクセスのスプリットトンネリングの使い方
スプリットトンネリング decides which apps skip the tunnel and which stay protected.
以下に、その使用方法をステップごとに説明します。
Step 1: Open Split Tunnel Settings
Click Settings, then choose the Split Tunnel tab.

プライベートインターネットアクセスのトラブルシューティング

📌 注記： PIA support answers around the clock if none of these fix it.
プライベートインターネットアクセスとは何ですか?
