What Is My IP

If you have just searched what is my ip, the tool above already has your answer: your public IP address, shown the moment this page loaded, along with your internet provider, your approximate location and your time zone. This page is part of Speed Test UK, and this guide explains what that address actually is, what each detail in the result means, what websites can and cannot learn from it, and what to do when the details look wrong.

An IP address is simply the number your connection uses to send and receive data on the internet. Every website you visit sees it, because without it the site would have nowhere to send the page back to. It works a little like a return address on a parcel: not your name, not your house, but enough to route things back to your connection. Understanding yours takes about five minutes, and it is genuinely useful — for fixing connection problems, setting up remote access, understanding your privacy, and checking whether a VPN is really working.

What Is an IP Address, in Plain English?

IP stands for Internet Protocol. An IP address is a label assigned by your internet provider to your connection. When you open a website, your device sends a request stamped with that address; the website reads it and sends the page back to the same place. At home, one public IP address usually covers your whole household: your router gives each phone, laptop and TV its own private address inside the home (you will see numbers like 192.168.1.42 in your router settings), then translates everything through the single public address. That translation is why every device in your house shows the same result on this page.

There are two versions in use. IPv4 addresses look like 86.142.7.19 — four numbers separated by dots. IPv6 addresses are longer, written in hexadecimal, and look like 2a00:23c7:5a01:9301::1. The world ran short of IPv4 addresses years ago, so IPv6 is gradually replacing it. Many UK connections now use both at once, which is why the tool above tries to show you one of each.

How to Use This What Is My IP Tool

There is almost nothing to do — but a tidy method helps if you are checking something specific, such as whether a VPN has connected or whether your provider has changed your address.

• Just open the page. Your public IP, provider, approximate location and time zone appear automatically. No sign-up, no app, nothing to install.
• Note which address is showing. The large address at the top is the one this connection actually used to reach us. The table underneath lists your IPv4 and IPv6 separately, where both could be detected.
• Copy it if you need it. Use the Copy button if a support agent, a game server admin or a work IT desk has asked for your address.
• Compare before and after. If you are testing a VPN or a router restart, leave the page open, make the change, then press Refresh. A changed address confirms the change worked.
• Check on each network. Run it once on home Wi-Fi and once on mobile data with Wi-Fi off. The two results will differ — different connections, different addresses.

Your Results Explained, Field by Field

Most IP checkers throw numbers at you without a word of explanation. Here is what each row of the result above actually means, and what is normal for a UK home connection.

How Accurate Is IP Location? Why the Town Is Often Wrong

This is the question that confuses people most. IP location databases do not track you — they record where your provider has registered or routed a block of addresses, which is often a regional network hub. A household in a Cornish village may show as Plymouth or even Exeter; a flat in Leeds may show as Manchester. Mobile connections are vaguer still, sometimes pointing at a city hundreds of miles away where the mobile network breaks out onto the internet. Treat the city as “roughly where your provider’s network surfaces”, not as your location.

It also means an IP address cannot identify a house or a person on its own. It identifies a connection at a moment in time. Only the provider can link an address and a timestamp to an account, and in the UK that information is disclosed through proper legal channels, not to websites or strangers. If you are worried about online privacy generally, the Information Commissioner’s Office (ICO) publishes plain-English guidance for the UK public on staying safe and understanding your rights online.

What an IP Address Reveals — and What It Does Not

Websites can see: your provider, your approximate region, your time zone, and whether your address looks like a home connection, a mobile connection, a business line or a VPN. That is how streaming services decide which country’s catalogue to show you, and how shops show prices in pounds without asking. Websites cannot see from your IP alone: your name, your home address, your browsing history, or what is on your devices. Your provider can link the address to your account, which is why using a trustworthy provider — and understanding its privacy policy — matters more than hiding the number itself.

Checking Your IP in the UK: Broadband, Mobile and CGNAT

A few quirks are specific to British connections, and none of the big American IP sites explain them.

Most UK home broadband addresses are dynamic. BT, Sky, TalkTalk, Virgin Media, EE and Plusnet generally change your address from time to time — when your router reconnects, after network maintenance, or simply on a schedule. That is not a fault and nothing to worry about. If you genuinely need an address that never changes (for a home server, CCTV access or some work systems), some providers offer a static IP on business packages or as an add-on; smaller UK providers often include one. Ask your provider rather than paying a stranger online.

Mobile data uses shared addresses (CGNAT). UK mobile networks place large numbers of customers behind a smaller pool of public addresses, a system called carrier-grade NAT. This is why your phone’s IP location can look wildly wrong and why your mobile address can change mid-journey. It is normal, and it also means your phone shares its public address with many other customers at the same time.

Your provider’s name may surprise you. Resold and wholesale connections often show the network owner rather than your brand. A customer of a smaller ISP riding on a big network, or a mobile brand owned by a larger group, may see the parent company’s name in the ISP row. That is the network doing its job, not an error.

How to Change or Hide Your IP Address

Sometimes there is a good reason to change your address: a gaming or work service has mistakenly blocked it, you are troubleshooting, or you simply value privacy on public Wi-Fi.

• Restart your router. On most UK home broadband, switching the router off for a few minutes and back on will often pick up a different dynamic address. Check this page before and after to confirm.
• Use a VPN. A VPN routes your traffic through its own servers, so websites see the VPN’s address instead of yours. This is the standard answer on public Wi-Fi and for privacy. Afterwards, re-run this tool: the provider and location should show the VPN’s, which proves it is working.
• Switch networks. Turning Wi-Fi off and using mobile data gives you your mobile network’s address instead — a quick test when a site misbehaves on one connection but not the other.

None of these make you anonymous in any absolute sense — your provider or VPN company still knows your real address — but they change what ordinary websites see, which is what most people actually want.

Troubleshooting: When the Result Looks Wrong

The tool cannot find my IP address

An ad blocker, a script-blocking extension or a strict work or school network may be blocking the lookup services this tool uses. Whitelist this page, pause the blocker, and press Refresh. If you are on a work VPN, the tool may also legitimately fail because the VPN only allows approved destinations.

The location shows a completely different town

Almost always the database pointing at your provider’s regional hub, as explained above. On mobile data, expect it. It does not mean your connection is routed wrongly or that anyone has moved your account.

My IPv6 shows “Not detected”

Either your provider has not enabled IPv6 on your line, your router has it switched off, or the network you are on (many public Wi-Fi systems, for example) is IPv4-only. Your connection works fine without it; nothing needs fixing.

The address is different from the one my router shows

Your router’s status page may show a private WAN address if your provider uses CGNAT, while this tool shows the true public address the internet sees. The one on this page is the one websites see — that is the one to quote to support desks.

What Is My IP – Frequently Asked Questions

What is my IP address right now?

It is the large address at the top of this page, detected automatically when the page loaded. Underneath it you will also find your IPv4 and IPv6 addresses listed separately where both are available, plus your provider and approximate location.

Can someone find my home address from my IP?

No. An IP address gives a rough region at best — often just the town where your provider’s network hub sits, and sometimes the wrong town entirely. Only your provider can link an IP address to an account holder, and they release that only through proper legal process.

Why does my IP address keep changing?

Because most UK home broadband and all UK mobile connections use dynamic addresses, reassigned when your router reconnects or on the provider’s schedule. It is normal and, for most households, mildly good for privacy. If you need a fixed address, ask your provider about a static IP.

What is the difference between a public and a private IP address?

Your public address is the single address your whole connection presents to the internet — the one this tool shows. Private addresses (starting 192.168., 10., or 172.16.–172.31.) are handed out by your router to devices inside your home and are never seen by websites.

Does a VPN really change my IP address?

Yes — websites then see the VPN server’s address and location instead of your provider’s. You can prove it on this page: check your address, connect the VPN, press Refresh, and the address, provider and location should all change to the VPN’s details. If they do not, the VPN is not routing your browser traffic.

Is it safe to share my IP address?

Sharing it with a support desk or a friend running a game server is routine and low-risk: every website you visit already sees it. Avoid posting it publicly alongside personal details, and never share it with someone who contacted you out of the blue claiming to be from your provider — UK providers do not cold-call asking for it.

Now Check How Well This Connection Performs

Knowing your address is half the story; knowing how the connection behaves is the other half. If pages feel slow or calls keep breaking up, run our broadband speed test for your download and upload speeds, then check responsiveness with the ping tester and stability with the jitter test. If results are good beside the router but poor elsewhere in the house, our Wi-Fi speed test guide will help you find the weak spots. And if you are comparing providers or thinking of switching, start with our overview of UK broadband providers — then come back to Speed Test UK any time you need to check your IP or your speed again.
