Every Method, One Table
Eight techniques can replace your IP address or crowd-blend it so websites cannot isolate you by address alone. Which one you pick depends on what you are hiding from, what you are willing to pay, and how much speed you can sacrifice.
| Method | Hides IP from sites? | Encrypts traffic? | Covers all apps? | Speed impact | Cost | Anonymity level |
|---|---|---|---|---|---|---|
| VPN | Yes | Yes | Yes | Low (10-15% overhead) | $3-$14/mo | Medium |
| Tor | Yes | Yes (3 layers) | Browser only | Very high (~50x slower) | Free | High |
| Proxy | Yes | No | Browser/app only | Low | Free-$$ | Low |
| Mobile data | Yes (shared pool) | No | Yes | Variable | Data plan | Very low |
| Smart DNS | No | No | Partial | None | $3-$7/mo | None |
| New ISP IP | Temporarily | No | Yes | None | Free | None |
| Router-level VPN | Yes | Yes | Yes (entire LAN) | Low-medium | VPN subscription | Medium |
| Business/corporate NAT | Crowd-blend only | No (employer sees all) | Yes | None | N/A | Very low |
For a quick ranked shortlist, see How to Hide Your IP Address. This post goes deeper on every method, including the two that guide skips: router-level VPN and what your work network actually does (and does not) hide.
Why Your IP Reveals More Than You Think
Your public IP address maps to an approximate location, your ISP, and a session-spanning identifier that ad networks use to correlate your activity across dozens of sites. For a full breakdown of what that exposure looks like in practice, see What Can Someone Do With Your IP Address.
Before making any changes, check what the outside world currently sees at My IP. That is the address you want to replace.
Method 1: VPN
A VPN encrypts every packet leaving your device and routes it through a server you choose, so websites see the server's IP, not yours. Every app on your device is covered, not just the browser. This is the most practical daily-use option for most people.
How the protocol matters
Modern VPN protocols divide into two camps. WireGuard is now the default at most reputable providers: it adds roughly 10-15% overhead compared to raw throughput and keeps latency additions under 1 ms on local connections. OpenVPN over TCP is slower (roughly half the throughput of WireGuard on the same hardware) but works through firewalls that block UDP, making it a useful fallback.
What "no-logs" actually means
The main trust concern with a VPN is that the provider can see your traffic. Choose one with independent third-party audits, not just a policy statement. NordVPN, for example, passed its sixth no-logs assurance engagement in December 2025, conducted by Deloitte Lithuania under ISAE 3000 standards. Deloitte reviewed server infrastructure and deployment configurations and found nothing that contradicted the no-logs claim. Audit reports exist for several other major providers as well.
Tradeoffs
| What you get | What you give up |
|---|---|
| IP hidden from every site | You must trust the VPN provider |
| Full traffic encryption | Monthly cost |
| All apps covered | Slightly higher latency |
| Choice of exit country | Some streaming services block VPN IPs |
Best for: daily browsing, streaming, public Wi-Fi, banking on shared networks, and any situation where you want full-device protection with minimal friction.
After connecting, run our VPN Leak Test to confirm your real IP, DNS, and WebRTC data are all hidden. A green indicator in the VPN app is not proof: leaks happen silently.
Method 2: Proxy
A proxy forwards your web requests through its own IP address. The website sees the proxy. That is where the similarity to a VPN ends.
Proxies do not encrypt traffic. The proxy operator can read everything you send in plaintext unless the destination uses HTTPS, in which case the TLS layer protects the content, but your DNS queries and connection metadata remain visible. SOCKS5 proxies handle any protocol (not just HTTP) and relay UDP traffic, making them useful for specific apps like torrent clients, but SOCKS5 still adds no encryption of its own.
Free proxies compound the reliability problem. They go offline frequently, and the operator's business model is often opaque.
Best for: a quick one-off IP change in a single browser tab when encryption is not a concern.
Not for: logins, payments, or anything requiring even basic security.
Method 3: Tor
Tor routes your traffic through three volunteer-operated relays, encrypting it at each hop so no single relay knows both who you are and what you are requesting. This three-hop architecture is structurally stronger than a VPN because no single entity holds the full picture.
The speed cost is structural
In a December 2025 benchmark, Tor Browser averaged around 5 Mbps download on a fiber connection while a VPN on the same line averaged close to 250 Mbps, about a 50x gap. Latency typically balloons from 20 ms on a local connection to 250-400 ms through a Tor circuit. That latency ceiling is built into the architecture; no hardware upgrade removes it. Streaming and large downloads are not practical.
Blocking and censorship
Many large sites route Tor exit nodes to CAPTCHA walls or block them outright. In countries that block Tor itself, the Tor Browser offers bridges (unlisted relays censors cannot easily find) and pluggable transports. Snowflake, one of those transports, disguises your Tor traffic as a WebRTC connection by relaying it through browser-based volunteer proxies, making it difficult for a censor to block without also breaking ordinary WebRTC use.
Scope
Tor only protects traffic inside the Tor Browser. Other apps on your device use your normal IP.
Best for: journalists, activists, whistleblowers, or anyone in an environment where Tor's superior anonymity justifies the speed penalty.
Not for: streaming, everyday browsing, or anything time-sensitive.
Method 4: Mobile Data
Switching from Wi-Fi to cellular data gives you a different IP address from your mobile carrier's pool immediately. Toggling airplane mode off and back on often triggers a fresh IP assignment on reconnect.
This is an IP change, not a privacy measure. Your carrier assigned the address and knows it is yours. Traffic is unencrypted at the application layer. If your carrier uses Carrier-Grade NAT (CGNAT), and most mobile carriers do, the public IP you receive may be shared with hundreds of other subscribers anyway, which means sites may already treat it as a flagged or CAPTCHA-triggering shared address.
My rule here: use this only when you need a quick escape from a site-specific IP block and have nothing else at hand. Never confuse an IP change with privacy.
Best for: bypassing a specific IP block fast.
Not for: any privacy or security need.
Method 5: Smart DNS
Smart DNS reroutes only your DNS queries and a small amount of connection metadata to make streaming services think you are in a different country. Your real IP remains visible to every website you visit. Your ISP can still see all your traffic.
The value is narrow: it works on devices that cannot run VPN apps, such as smart TVs, game consoles, and set-top boxes, and it imposes no speed penalty because the bulk of traffic goes direct. Outside of geo-unblocking on constrained devices, it provides nothing.
Best for: unlocking geo-restricted streaming libraries on devices that cannot install a VPN app.
Not for: any privacy or security goal.
Method 6: Request a New IP From Your ISP
Restarting your modem can sometimes trigger a new IP assignment from your ISP's DHCP pool. Whether it works depends on your ISP's lease duration: some hold leases for hours or days, so the same address returns. A new address is traceable, fully visible, and tied to your account. This is troubleshooting, not privacy.
Best for: escaping a stale routing problem or a specific IP block.
Not for: privacy of any kind.
Method 7: Router-Level VPN
Installing a VPN at the router level covers every device on your network without touching any individual device. Your smart TV, game console, IoT sensors, and every phone that connects to your Wi-Fi all exit through the VPN server's IP. No per-device app is needed.
Three paths to a VPN router
Option 1: Buy a pre-configured router. GL.iNet makes a range of compact OpenWRT-based routers with built-in WireGuard and OpenVPN support accessible through a web admin panel. No firmware flashing required. You enter your VPN provider's credentials, enable the kill switch, and every connected device is covered.
Option 2: Flash third-party firmware. DD-WRT and OpenWRT run on hundreds of consumer router models and add native VPN client support. DD-WRT requires build 43045 or later for WireGuard. OpenWRT installs WireGuard via opkg install wireguard-tools luci-proto-wireguard.
Option 3: Stock firmware with native VPN client. Asus routers running Asuswrt-Merlin (version 386.7 and later) have native WireGuard client support. Stock Asus firmware supports WireGuard in VPN Fusion on models with firmware version 3.0.0.4.388.23000 and above, including the RT-AX86U and RT-AX88U. WireGuard support in stock firmware is limited to Wi-Fi 6 and Wi-Fi 7 models.
Protocol choice on a router
WireGuard is the right choice on a router when your provider supports it. Its CPU requirements are dramatically lower than OpenVPN's, which matters because a router's processor is far weaker than a phone or laptop. OpenVPN's higher per-packet CPU cost can saturate a mid-range router's processor at modest speeds. WireGuard on the same hardware handles considerably more throughput and is the protocol recommended by GL.iNet for their own devices.
The kill switch matters more at the router level
If the VPN tunnel drops and you have no kill switch, every device on your network briefly uses your real ISP IP, and most devices reconnect automatically without alerting you. A kill switch configured at the router firewall blocks all WAN traffic the moment the tunnel goes down. DD-WRT, OpenWRT, GL.iNet, and Asuswrt-Merlin all support this.
Best for: households with many devices, IoT devices that cannot run VPN apps, or anyone who wants whole-home coverage without managing per-device software.
Not for: users who want to split traffic between VPN and direct without advanced firewall configuration.
Check that your router VPN coverage is working by running our VPN Leak Test from any device on your network.
Method 8: Business and Corporate NAT
When you are on a corporate, university, or large office network, all outbound traffic typically shares one or a small pool of public IP addresses via NAT at the network edge. From a website's perspective, your individual IP is indistinguishable from your colleagues'. This is the same crowd-blending effect that CGNAT creates for mobile subscribers.
This is not a privacy tool you activate. It is a network architecture your employer controls. And the critical side of that: your employer maps every internal private IP to your account, logs those connections, and on many corporate networks runs TLS inspection that allows the IT team to read HTTPS content as well. You are invisible to external sites. You are highly visible internally.
In practice, corporate NAT obscures you from external IP-based tracking while exposing you to more monitoring than a home connection. For context on what private versus public IPs mean in your network, see Public vs Private IP Address.
The crowd-blend benefit is real for reputation: shared egress IPs sometimes bypass IP reputation blocks that target residential ranges. But never assume a work network is private.
Combining Methods
Router-level VPN plus Tor gives you strong anonymity with coverage for all devices, at the cost of Tor's speed penalty on every connection. When you run Tor inside a VPN connection, your real IP is hidden from the Tor entry node, and your ISP sees only that you are connected to the VPN rather than that you are using Tor.
For most people, a well-configured VPN running WireGuard covers the practical threat model: IP hidden from sites, traffic encrypted from ISPs and public Wi-Fi eavesdroppers, all devices covered, speed acceptable for streaming and gaming. Run the Browser Fingerprint tool to see what your browser reveals beyond your IP, because address-level protection alone does not stop fingerprinting-based tracking.
FAQ
Can I install a VPN on my router without flashing new firmware?
It depends on the router. Asus routers with stock firmware on Wi-Fi 6 and Wi-Fi 7 models support WireGuard via VPN Fusion from firmware version 3.0.0.4.388.23000 onward. GL.iNet routers ship with OpenWRT and a built-in VPN client UI, so no firmware change is needed at all. For most other consumer routers, you will need to install DD-WRT or OpenWRT to get a usable VPN client. Check your router's model against the DD-WRT and OpenWRT device compatibility databases before committing to a VPN subscription.
Does a router VPN slow down every device on my network?
Yes, but how much depends on your router's processor and the VPN protocol. WireGuard on a modern mid-range router typically delivers a few hundred Mbps, fast enough for 4K streaming and video calls. OpenVPN on the same hardware delivers considerably less because its higher per-packet CPU cost bottlenecks weak router processors far below what WireGuard achieves. If your ISP connection is above 100-200 Mbps, protocol choice at the router matters considerably.
Does my work or school network hide my IP from websites I visit?
It hides your personal IP address. External websites see one of your organization's public IP addresses, not yours. However, your employer or institution sees exactly which sites you visit and when, because the NAT device maps your internal IP to your account. On many corporate networks, TLS inspection allows IT staff to read HTTPS content as well. Work and school networks crowd-blend your IP externally while exposing your traffic internally.
Which method hides my IP from my own ISP?
A VPN and Tor both hide what you are doing from your ISP. With a VPN, your ISP sees encrypted traffic going to the VPN server and nothing else. With Tor, your ISP sees an encrypted connection to the Tor entry node. Proxies, mobile data, Smart DNS, and modem restarts do not hide your activity from your ISP at all.
Do I still need a VPN if my ISP or carrier uses CGNAT?
Yes. CGNAT hides you from external sites by putting many subscribers behind one public IP, which provides crowd-blending. But your ISP still knows exactly which subscriber made each connection: the NAT table maps every session to your account. CGNAT offers no protection from your ISP or from any party that can compel your ISP. A VPN encrypts traffic before it reaches the ISP, so your ISP cannot see which sites you visit. That protection is entirely separate from what CGNAT provides.
