What covering your IP address actually does
Your IP address is a number that identifies your device on the internet — like a return address on a letter. Websites, apps, and internet service providers can see it. Covering your IP address means routing your traffic through another computer so websites see that computer's address instead of yours.
This does three things: it hides your physical location from websites you visit, it makes it harder for someone on your home network to see what you're doing, and it prevents your internet service provider from building a detailed log of which websites you visit. It does not make you anonymous, encrypt your data by itself, or protect you from viruses. Those are separate problems that need separate solutions.
The trade-off is real: your traffic moves through an extra step, so websites load slightly slower. You're also trusting whoever runs that middle computer to not log your activity themselves. The three main methods — VPN, proxy, and Tor — each have different speeds, different trust requirements, and different reasons to use them.
Key Takeaways
- A VPN encrypts your traffic and routes it through a company's server, hiding your IP from websites but not from your internet service provider if they're paying attention to connection patterns.
- A proxy hides your IP but does not encrypt your traffic, so it's useful for bypassing network blocks but not for hiding what you're doing from someone monitoring your connection.
- Tor routes your traffic through multiple computers run by volunteers, making it very hard to trace, but it's noticeably slower and some websites block it.
- Free VPNs and proxies often log your activity or inject ads, so if you choose one, read the privacy policy and assume they can see your unencrypted data.
- Covering your IP address does not protect you from malware, phishing, or account takeovers — you still need strong passwords, two-factor authentication, and caution with links.
VPN: the most common choice for everyday use
A VPN (virtual private network) encrypts all your traffic and sends it through a company's server. Websites see the VPN server's IP address, not yours. Your internet service provider sees that you're connected to a VPN, but not which websites you visit or what you do there.
On Windows, macOS, iOS, and Android, you install a VPN app, open it, and click connect. Your device then routes all internet traffic through the VPN's server automatically. Most VPNs let you choose which country's server to use, which changes what IP address websites see.
The catch: you're trusting the VPN company not to log your activity. Read the privacy policy. Look for "no-logs" or "zero-logs" claims, but understand that no-logs is a promise, not something you can verify. Some VPNs that claim no-logs have been subpoenaed and had nothing to hand over, which is a good sign. Others have been caught logging despite their claims. Paid VPNs have more incentive to keep their promise than free ones, because they have paying customers to lose.
Speed varies by VPN and by which server you connect to. A server close to you is usually faster. Some VPNs are noticeably slower than others — test before paying for a year. Many VPNs offer a free trial or a money-back may provide, so you can try them on your actual connection.
Proxy: hiding your IP without encryption
A proxy is a middle computer that forwards your requests to websites. Websites see the proxy's IP address instead of yours, but your traffic is not encrypted. Anyone monitoring your connection — your internet service provider, your employer, someone on your home network — can still see which websites you visit and what you do there.
Proxies are useful for one specific thing: bypassing network blocks. If your workplace or school blocks a website, a proxy can get around that because the network sees a request to the proxy server, not to the blocked site. They're also faster than VPNs because there's no encryption overhead.
You set a proxy in your device's network settings (on Windows, that's Settings > Network & Internet > Proxy; on macOS, System Settings > Network > Wi-Fi > Details > Proxies). Some apps let you set a proxy just for that app instead of your whole device. Many free proxies inject ads or log your activity, so the same caution applies: if you don't pay, you're the product.
Tor: maximum difficulty to trace, but noticeably slower
Tor is free software that routes your traffic through a chain of volunteer-run computers, each one encrypting a layer of your data. By the time your traffic reaches a website, it's been through multiple hops and the website can't trace it back to you. Even the Tor network itself can't see both where you came from and where you're going.
read the Tor Browser from torproject.org (not from anywhere else — there are fake versions). It's a modified version of Firefox that connects to the Tor network automatically. Open it, wait for it to connect, and browse normally. Websites see an IP address from the Tor network, not yours.
Tor is much slower than a VPN because your traffic bounces through multiple computers. A page that loads in one second on a VPN might take five seconds on Tor. Some websites block Tor exit nodes because they're used for abuse, so you may see "access denied" messages. Tor is also more visible — your internet service provider can see that you're using Tor, even if they can't see what you're doing.
Use Tor if you need maximum protection from being traced — journalists, activists, and people in countries with heavy internet censorship. Use it if you're concerned about a powerful adversary. Don't use it just to hide from your internet service provider; a VPN does that job faster and is good enough for most people.
What to do if you're on a shared home network
If you live with roommates or family, they can see your traffic if they're technically inclined and on the same Wi-Fi. A VPN or proxy hides your activity from them because your device encrypts the traffic before it leaves your device. They can see that you're using a VPN, but not which websites you visit.
If you want to hide even the fact that you're using a VPN, that's harder. Some routers let you set a VPN for the whole network, so everyone's traffic goes through it and it's not obvious who's using what. That requires access to your router's settings and a VPN that supports it — not all do. Talk to whoever manages the network.
If you're concerned about someone on your network monitoring you, a VPN is the practical solution. If you're concerned about the router owner themselves, you need encryption at the process level — that means using websites with HTTPS (the padlock in your browser), using encrypted messaging apps, and not trusting the network itself.
Combining IP covering with other security practices
Hiding your IP address is one piece of security, not the whole picture. A VPN does not protect you from phishing emails, malware, or weak passwords. It does not stop someone from hacking your email account or stealing your credit card number from a data breach.
Use a VPN or Tor alongside these practices: use a password manager to create and store strong, unique passwords for each site; turn on two-factor authentication on important accounts like email and banking; be skeptical of links in emails and messages, especially ones asking you to log in; keep your operating system and apps updated; and use antivirus software if you're on Windows.
IP covering is most useful when combined with HTTPS websites (look for the padlock in your browser's address bar). HTTPS encrypts the content of your communication, so even your internet service provider can't see what you're sending. A VPN plus HTTPS is a strong combination.
Free versus paid: what you're trading
Free VPNs and proxies exist, but they make money somehow. Some inject ads into your traffic. Some log your activity and sell it to advertisers. Some have slower speeds because they prioritize paying customers. Some have limited data — you can only use a certain amount per month before they cut you off.
A paid VPN costs between $3 and $12 per month depending on the provider and how long you commit. You're paying for faster speeds, better privacy policies, and customer support. Reputable paid VPNs include Mullvad, ProtonVPN, and IVPN, though there are others. Read reviews from security researchers, not just from the VPN company's marketing.
If you use a free VPN, assume the company can see your unencrypted data. Don't log into sensitive accounts, don't enter credit card numbers, and don't assume your activity is private. For casual browsing where you don't care if the VPN company sees what you're doing, free is fine. For anything sensitive, paid is worth the cost.
Frequently Asked Questions
Will a VPN make me completely anonymous?
No. A VPN hides your IP address from websites, but the VPN company can see your traffic. If you log into your email or social media account while using a VPN, those companies know who you are. Websites can also track you through cookies and browser fingerprinting. A VPN is one layer of privacy, not anonymity.
Can my internet service provider see what I'm doing if I use a VPN?
They can see that you're using a VPN and how much data you're sending, but not which websites you visit or what you do there. If they're very determined, they might be able to infer some activity from the amount of data and timing, but they can't see the content.
Is Tor illegal?
No. Tor itself is legal in most countries. Using Tor to access illegal content is illegal, just like using a regular browser to access illegal content is illegal. Some countries block or discourage Tor, but using it is not a crime in the United States, Canada, UK, or most of Europe.
Do I need a VPN if I use HTTPS websites?
HTTPS encrypts the content of your communication, so your internet service provider can't see what you're sending. They can still see which websites you visit. A VPN hides which websites you visit. Together they're stronger, but HTTPS alone is better than nothing.
What if a website blocks my VPN?
Some websites block known VPN IP addresses to prevent abuse or enforce geographic restrictions. If a site blocks you, try a different VPN server in a different country, or disconnect from the VPN. Some VPNs offer "obfuscation" features that try to hide the fact that you're using a VPN, but not all websites can be bypassed.
