Direct answer: A website usually sees your public IP address, not your device itself. That visible IP can change if you use a VPN, proxy server, Tor Browser, mobile data or a network using NAT or CGNAT. The key difference is that some options improve privacy properly, whilst others simply show a different connection point.
- A VPN routes all device traffic through a provider server, so the website sees the VPN server IP.
- A proxy often works only inside one browser or app, not across your whole connection.
- Tor hides your IP more thoroughly than a normal VPN, but it is usually much slower.
- Switching network changes your public IP, but it is not the same as proper privacy protection.
- CGNAT means several users can share one public IP, though the ISP still keeps session records.
If you are checking how your connection appears online, it helps to separate privacy tools from broadband setup. The target phrase sums it up clearly: 1. VPN Your device connects to the VPN provider first. The website then sees the VPN server’s IP address, not your home or mobile IP. 2. Proxy server Similar idea, but usually works at browser or app level rather than protecting all traffic from the device. 3. Tor browser Routes traffic through several volunteer-run servers. The website sees the final Tor exit node IP, not yours. Slower, but stronger for anonymity than a normal VPN. 4. Mobile data or different network Switching from home broadband to mobile data changes the public IP, but it does not remove the need for one. 5. NAT / CGNAT Many homes and mobile networks already share one public IP across multiple users or devices. This can make attribution less direct, but the ISP still knows which customer or session used it.
For households comparing providers, this matters because network setup affects privacy, remote working and troubleshooting, but it does not replace choosing the right broadband package. If you want to compare broadband deals by postcode, start with what is available at your address first.
What does a website actually see when you connect?
A website normally sees the public IP address assigned to your connection.
That public IP often belongs to your home broadband line, your business broadband service, or your mobile network at that moment. It does not automatically reveal your name or full address to the website, but it can indicate your approximate location and your provider.
In UK broadband terms, that visible address usually comes from the network run behind providers such as BT, Sky, TalkTalk, Vodafone, EE, Plusnet, Virgin Media or an altnet. The website sees the outward-facing IP, not the internal IP address used by your laptop or router inside the home.
How does a VPN change the IP a website sees?
A VPN makes the website see the VPN server, not your direct home connection.
With a VPN, your device connects to the VPN provider first. From there, your traffic goes out to the wider internet. That means the destination website sees the VPN server IP address rather than the public IP issued over your broadband line.
This is the clearest answer to the question most people are actually asking. If you use full fibre, FTTC or business broadband, the access technology does not change the principle. The website still sees the endpoint that is presenting the traffic, and with a VPN that endpoint is the VPN provider.
The practical trade-off is speed and trust. A VPN can reduce latency-sensitive performance and add overhead, especially on slower packages or busy Wi-Fi. You are also shifting trust from your broadband provider to the VPN company handling that traffic.
Is a proxy server the same as a VPN?
No, a proxy and a VPN can look similar from a website’s side, but they protect traffic differently.
A proxy server usually covers one application, often a browser. If that app is configured to use a proxy, the website sees the proxy server’s IP instead of your normal public IP. Other apps on the same device may still connect directly through your broadband line.
That distinction matters at home and at work. If someone assumes a proxy protects everything on a household connection, they can end up exposing traffic from email clients, software updates or other apps outside the browser session. A VPN is generally broader because it is designed to route all device traffic through the encrypted tunnel.
Why is Tor different from a normal VPN?
Tor is built for stronger anonymity, but the trade-off is speed and convenience.
Tor Browser sends traffic through multiple volunteer-run relays before it reaches the destination website. The site sees the final exit node IP, not your home IP. Because the route changes and passes through several hops, tracing becomes harder than with a standard commercial VPN setup.
For ordinary household broadband use, Tor is often far slower than a direct connection. It is also less practical for day-to-day tasks that depend on consistent speed or low delay. If you are working from home on Openreach-based FTTP or comparing business broadband options for cloud tools, Tor is not a substitute for a stable connection.
Does switching to mobile data or another network hide your IP?
It changes the visible IP, but it does not give you the same privacy model as a VPN or Tor.
If you leave home Wi-Fi and connect through another network, the website sees a different public IP because you are using a different internet connection. That is all. It does not mean your browsing is suddenly anonymous, and it does not remove the need for proper privacy tools if that is your aim.
This is worth understanding for people troubleshooting access issues. If a service works on one connection but not another, the problem may be tied to IP reputation, routing or provider-specific filtering, not your laptop itself. That can be relevant when moving home, switching provider, or deciding whether a standard home package is enough for remote working.
What are NAT and CGNAT, and do they matter?
Yes, because NAT and CGNAT mean several devices or customers can appear under one public IP.
NAT, short for Network Address Translation, is common on home routers. Your devices use local addresses inside the house, while the router presents one public IP to the internet. CGNAT, or Carrier-Grade NAT, works on a larger scale inside the provider network, where multiple customers can share one public IP.
From a website’s point of view, that shared address can make attribution less direct. However, it does not make activity untraceable. The provider still knows which customer session was using that shared public IP at a particular time. Ofcom and other official guidance around internet access and provider processes make that distinction important.
This also affects practical broadband questions. Some advanced home setups, hosting tasks and remote access tools work better with a dedicated public IP than behind CGNAT. For many households it makes no noticeable difference, but for home offices and small firms it is worth checking before you switch.
Which option is best for privacy, and which is just a different route?
Tor gives the strongest anonymity of the five, whilst VPNs are usually the most practical everyday option.
Here is the simplest comparison:
| Option | What the website sees | Privacy strength | Main trade-off | |---|---|---|---| | VPN | VPN server IP | Good | Depends on provider trust and speed | | Proxy server | Proxy IP for that app | Limited to setup | Often app-only, not full-device | | Tor Browser | Tor exit node IP | Strongest here | Slow performance | | Different network | New network IP | Low by itself | Just a changed connection | | NAT or CGNAT | Shared public IP | Limited by itself | ISP can still identify sessions |
If your concern is everyday privacy on home broadband, a VPN is usually the practical middle ground. If your concern is stronger anonymity, Tor is more effective but much less convenient. If your concern is broadband value, speed or reliability, these tools are separate from the package you buy.
That is where address-level comparison helps more than generic rankings. You can review packages, total contract cost and setup differences through the switching hub, the broadband speed guide, deals under £25, deals under £30, FTTP broadband deals, the business broadband hub, social tariffs in the UK, and provider comparison pages once you know what is actually available where you live.
Does this affect your broadband choice at home?
Yes, but only in a practical sense, not because one provider automatically makes you anonymous.
Your provider choice affects speed, reliability, contract terms, installation timing and whether full fibre is available. It does not remove the need for a VPN if you want websites to see a different IP from your home connection. Openreach, Virgin Media and altnet availability all matter for performance, but privacy tools sit on top of that connection.
For remote workers and small businesses, the more useful question is whether the line is stable enough for secure tools to run comfortably. If you are already weighing FTTP against older FTTC services, or choosing between residential and business broadband, match the package to workload first. Then deal with VPN or remote-access needs separately.
If you are comparing options now, compare broadband deals by postcode to see the actual packages and contract terms available at your address.
FAQs
Does a VPN hide my IP address from websites?
Yes. The website sees the VPN server’s IP address rather than the public IP from your home broadband or current network.
Is a proxy enough if I only use a browser?
Sometimes, but only for that configured browser or app. It does not usually protect all traffic from the device.
Is Tor better than a VPN for anonymity?
Yes. Tor is generally stronger for anonymity because it routes traffic through several relays, but it is much slower and less convenient.
If my broadband uses CGNAT, am I anonymous already?
No. CGNAT means a public IP is shared, but your ISP can still identify which customer session used it at a given time.
Does changing broadband provider change my public IP?
Usually, yes. A new provider or network setup often means a different public IP, but that alone is not a privacy tool.
Do I need faster broadband to use a VPN?
Not always, but faster and more stable broadband makes VPN use more comfortable, especially for home working, large uploads and multiple users.
If you are weighing privacy, performance and value at the same time, the broadband part is still the foundation. A slow or poor-value package stays slow or poor value whether you use a VPN or not. To check the options at your address and switch with more confidence, compare broadband deals by postcode.
