What Does a VPN Hide? What It Protects and What It Doesn’t
When you use a VPN, you’re told it keeps you private online. So what does a VPN hide, exactly? The short answer: a VPN hides your IP address and encrypts your internet traffic, so your internet service provider (ISP), network owners, and websites see much less about you. It doesn’t hide everything, though.
This guide explains what a VPN actually hides, what it can’t hide, and how to close the gaps. You’ll know exactly what a VPN can do for your privacy and where you need other tools.
How a VPN Hides Your Data
When you connect to a VPN, your device creates an encrypted tunnel to a VPN server. All your internet traffic goes through that tunnel before it reaches the open internet.
Two things happen:
- The VPN encrypts your data between your device and the VPN server. Anyone watching the connection sees scrambled data.
- The VPN changes your IP address. Websites see the IP address of the VPN server instead of your real IP address.
That’s the core of what a VPN is: encryption plus a new IP. Everything a VPN can hide comes from those two features. If you want the technical side in plain words, read our guide to VPN encryption.
What a VPN Hides
Your IP Address
Your IP address is like a return address for your internet connection. It can reveal your approximate location and your ISP. A VPN hides your IP from the websites and apps you use. They see the VPN server’s IP address instead.
You can check this yourself. Look at your IP on our IP checker, connect to a VPN, and check again. The address and location should change.
Your Approximate Location
Because websites see the VPN server’s IP, they also see that server’s location. If you connect to a server in Germany, sites will think you’re in Germany. That helps hide your location from websites, advertisers, and other users.
Your Browsing Activity From Your ISP
Without a VPN, your ISP can see which websites you visit, when, and for how long. With a VPN, your traffic is unreadable to your ISP. It sees that you’re connected to a VPN server and how much data you use, but not the websites you visit or what you do on them.
That also makes it harder for an ISP to slow down specific services with bandwidth throttling, since it can’t tell what your traffic is.
Your Online Activities on Public Wi-Fi
On public Wi-Fi at a café, airport, or hotel, the network owner and other users on the network may try to watch your traffic. A VPN encrypts everything between your device and the VPN server, so sensitive information like logins and messages is much harder for a hacker to intercept.
Your Downloads and Torrenting
A VPN hides P2P traffic from your ISP and replaces your IP address in the torrent swarm with the VPN server’s IP. We cover this in detail in our guide: Does a VPN hide torrenting from your ISP?
Your DNS Requests
Every time you type a web address, your device sends a DNS request to look up the site. Without a VPN, those requests usually go to your ISP. A good VPN sends them through the encrypted tunnel to its own DNS servers.
What a VPN Doesn’t Hide
A VPN is one useful privacy tool, but it doesn’t hide everything. Here’s what a VPN can’t hide.
The Fact That You’re Using a VPN
Your ISP can still see that you’re connected to a VPN server and the IP address of the VPN. Websites can often tell too, since VPN server IP addresses are publicly known. Some VPNs offer obfuscation to disguise VPN traffic as regular HTTPS traffic, but it isn’t foolproof against deep packet inspection.
Your Activity on Accounts You’re Logged Into
If you’re signed in to Google, Facebook, or any other service, it knows it’s you. A VPN changes your IP address, but it doesn’t hide your activity from the accounts you’re logged into. A search engine you’re signed in to still records your searches.
Cookies and Browser Fingerprinting
Websites track you with cookies and by building a “fingerprint” from your browser, screen size, fonts, and settings. A VPN doesn’t hide your browser details. Clear your cookies, use a privacy-focused browser, and block trackers to reduce this.
Your Data From the VPN Provider
Your traffic goes through the VPN provider’s servers, so you’re trusting the provider. Choose a no-logs VPN that doesn’t store your browsing activity. You can read Planet VPN’s no-logs policy to see exactly what we do and don’t keep.
Your MAC Address
A VPN can’t hide your MAC address from the local network you’re connected to, like your router or a public Wi-Fi hotspot. Your MAC address doesn’t travel past the local network, though, so websites never see it. Most phones now use a random MAC address for each Wi-Fi network.
Your IP If the VPN Connection Drops
If your VPN connection drops, your device may go back to your normal connection and expose your real IP address. A Kill Switch prevents this by cutting your internet until the VPN reconnects. Learn more in our guide to the VPN Kill Switch.
IP Leaks Through Your Browser
Some browsers can leak your real IP through a feature called WebRTC, even when you’re connected to your VPN. Run our WebRTC leak test to check.
Malware, Phishing, and Scams
A VPN encrypts your connection. It won’t stop you from downloading malware or clicking a phishing link. You still need antivirus software, a firewall, and careful habits.
VPN vs. Private Browsing Mode
People often think private browsing mode hides the same things. It doesn’t. Private browsing mode (Incognito) only stops your browser from saving your history, cookies, and form data on your device. Your ISP, your network, and the websites you visit can still see your activity and your IP address.
| What’s hidden | Private browsing mode | VPN |
|---|---|---|
| Browsing history on your device | Yes | No |
| Your IP address from websites | No | Yes |
| Websites you visit from your ISP | No | Yes |
| Traffic on public Wi-Fi | No | Yes |
| Activity on accounts you’re logged into | No | No |
| Cookies after you close the window | Yes | No |
Using both together gives you more privacy than either alone.
Quick Summary: What a VPN Hides
| Data | Hidden by a VPN? |
|---|---|
| Your real IP address | Yes, from websites and apps |
| Your approximate location | Yes, from websites and apps |
| Websites you visit | Yes, from your ISP and local network |
| DNS requests | Yes, with a good VPN |
| Content of your traffic on public Wi-Fi | Yes |
| The fact that you’re using a VPN | No |
| Activity on accounts you’re logged into | No |
| Cookies and browser fingerprint | No |
| MAC address on your local network | No |
How to Choose a VPN for Privacy
When you choose a VPN, look for these features. Together they help a VPN hide as much as possible:
- A clear no-logs policy, so the VPN provider doesn’t store your browsing activity
- Reliable encryption and modern protocols
- A Kill Switch to protect your IP if the VPN connection drops
- DNS leak protection, so your DNS requests stay inside the VPN tunnel
- Apps for all your devices, so your phone is protected as well as your computer
You can get Planet VPN for Android, iOS, Windows, Mac, and your browser from the download page.

Frequently Asked Questions
What does a VPN hide from your ISP?
A VPN hides the websites you visit, the content of your traffic, and your DNS requests from your ISP. Your ISP can still see that you’re connected to a VPN server, how much data you use, and when you’re online.
Does a VPN hide your location?
A VPN hides your location from websites and apps by showing them the location of the VPN server instead. It doesn’t hide your location from your mobile carrier, and apps with GPS access can still use your device location.
Can my ISP see what I do with a VPN?
No. When you’re connected to a VPN, your ISP can’t see the websites you visit or what you do on them. It can only see encrypted traffic going to the VPN server’s IP address.
Can websites still track me if I use a VPN?
A VPN makes tracking harder, but it doesn’t make you anonymous. Websites can still identify you through logged-in accounts, cookies, and browser fingerprinting. A VPN provider could also hand over data if it keeps logs, which is why a no-logs VPN matters.
Does a VPN hide my browsing history?
A VPN hides your browsing activity from your ISP and the network you’re on. It doesn’t delete the history saved in your browser. Use private browsing mode or clear your history to remove it from your device.
Does a VPN hide my IP address from apps?
Yes. Apps that connect to the internet see the IP address of the VPN server instead of your real IP. Apps can still identify you through your account or device permissions like GPS.
Do I need a VPN if I use HTTPS?
HTTPS encrypts the content of your connection to a website, but your ISP can still see which sites you visit. A VPN hides that too, and it protects apps and connections that don’t use HTTPS.
