Why your IP might not change on a VPN

If you connected to a VPN and this tool still shows your real IP, one of these is the cause. The tool is not caching, it is a network-level issue.

SymptomLikely causeFix
IP unchanged after connecting the VPNSplit tunnelingCheck your VPN settings for split tunneling or app exclusions and make sure your browser is inside the tunnel.
IP shows a different country but the same ISPProxy mode, not a full tunnelSome VPNs default to a browser proxy instead of a full-device tunnel. Switch to the full tunnel mode.
IP is your real IPv4 but a different IPv6IPv6 leakYour VPN tunnels IPv4 only. Either disable IPv6 on your device or enable IPv6 tunneling in the VPN.
IP unchanged, VPN shows ConnectedTunnel is not actually upVerify with the VPN provider's own IP-check page. If it also shows your real IP, restart the VPN client.
IP is the VPN's, but the location is wrongGeolocation by ISP registrationNormal. Geolocation uses the ISP's registered address, not the physical exit node. Country is usually right; city is often wrong.
IP changes every few minutesDynamic IP from your ISP or VPNConsumer ISPs rotate IPs; so do many VPNs. This is expected, not a bug.

Not a VPN user? This table is still useful if you are on a corporate network, behind a proxy, or on a mobile carrier that transparently proxies traffic.

What every field means

An IP lookup returns a surprising amount. Here is what each field actually tells you.

Why this beats other IP lookup sites

Most IP lookup sites are ad-stuffed single-purpose pages that show a stale cached answer. This one shows a live IP with VPN-aware diagnostics.

How it works

  1. 1

    Your IP loads automatically

    As soon as the page opens, the tool fetches and displays your own public IP with location, ISP and timezone. No click required.

  2. 2

    It refreshes when you come back to the tab

    Connected to a VPN in another app? Switch back to this tab and your IP refreshes automatically. You can also click Refresh IP at any time.

  3. 3

    Look up anything else

    Type any IP address (IPv4 or IPv6) or domain name into the search box, hit Enter, and the tool resolves it and shows the full detail set.

Everything you get for free

  • Auto-detects your IP on load

    No need to click anything, the tool immediately shows your own public IP address with full details. Useful when you need your IP for whitelisting, port forwarding, or just to check what the outside world sees.

  • Live refresh when you return to the tab

    Connect to a VPN, switch back to this tab, and your IP refreshes automatically within a second. No manual reload needed. The tool listens for tab visibility changes and re-queries when you come back.

  • Cache-buster, so you never see a stale IP

    Every request carries a unique timestamp parameter and uses cache: no-store, so no CDN, proxy, or browser cache can serve an old answer. When your IP changes, this tool sees it on the very next request.

  • VPN diagnostics on the result page

    If you are on a VPN and still see your real IP, the result page tells you the three most likely causes: split tunneling, IPv6 leak, or a VPN that reports Connected without a live tunnel. No need to guess.

  • Look up any IP or domain

    Type any IPv4 address, IPv6 address, or domain name (google.com, cloudflare.com). The tool resolves it and returns the same information set. Perfect for checking where a domain is hosted or where a suspicious IP is coming from.

  • Geolocation with map link

    Country, region, city, postal code, latitude and longitude, with a single click to open the coordinates in Google Maps. Useful for confirming where a VPN exit is, where a game server lives, or where a spam email originated.

  • ISP, ASN and organisation

    See which ISP owns the IP, what autonomous system number it belongs to, and which organisation registered the range. The first step in any IP reputation investigation.

  • Timezone with a live local clock

    The tool shows the timezone ID, abbreviation, UTC offset and current DST state, and a live clock ticking away in that timezone. No need to remember what IST or PDT mean at this time of year.

  • Copy each field in one tap

    Every value, the IP itself, the coordinates, the ASN, the ISP name, has a copy button that appears on hover. Building a report or filing a ticket? Grab exactly what you need, nothing more.

  • Recent lookups saved locally

    The last six IPs or domains you looked up are stored in your browser so you can jump back to them without retyping. Clear them at any time with one tap, they never leave your device.

  • Honest about accuracy limits

    IP geolocation is not GPS. Most tools hide that. This one explains why the country is usually right but the city can be wrong, especially on VPNs, mobile networks, and large national ISPs. Realistic expectations beat false precision.

What people use it for

  • Check your public IP

    The single most common use: what IP does the outside world see for you right now? Useful before whitelisting yourself on a remote server, before a video call, or when a website is misbehaving.

  • Verify your VPN is working

    Connect to a VPN, return to this tab, and the IP refreshes automatically. If it matches the VPN exit country, the tunnel is live. If it still shows your ISP, the VPN is split-tunneling or not actually connected.

  • Investigate a suspicious IP

    An email came from a weird IP, or your server logs show repeated attempts from an address. Look it up to see the ISP, country and organisation, the first step in deciding whether to block it.

  • Find where a domain is hosted

    Enter any domain name and see the country and ISP of the machine that serves it. Quick way to guess whether a site is behind Cloudflare, AWS, or a regional host.

  • Confirm a game server location

    Before joining a match, look up the server IP to see the country and ISP. Explains a lot about why your ping is what it is.

  • Remote team member support

    When a colleague in another country has connectivity issues, ask for their public IP and look it up. You immediately know which ISP they are on and can search for known outages.

Questions people ask

What is an IP address lookup?

An IP address lookup resolves an IP number (like 8.8.8.8) into useful information about who owns it and where it is registered. That typically includes the ISP, the autonomous system (ASN), the country, sometimes the region and city, the timezone, and the geographic coordinates of the ISP's registered range. It is not the same as tracing a person, the information comes from public registry databases.

Why does my IP not change when I connect to a VPN?

Three common causes. First, split tunneling: many VPNs only route certain apps through the tunnel, so your browser keeps using your real IP. Check the VPN's settings for split tunneling or app exclusions and make sure your browser is included. Second, IPv6 leak: some VPNs only tunnel IPv4, so if the site is reachable over IPv6 your request goes around the tunnel. Third, false Connected state: some VPN clients show Connected without an actual tunnel being established. Verify with the VPN provider's own IP-check page.

Does this tool refresh automatically when I come back after connecting the VPN?

Yes. The tool listens for tab visibility changes. When you switch to your VPN app, connect, and then switch back to this tab, the IP refreshes automatically within about a second. There is also a manual Refresh IP button in the top-right of the result card, and a My IP button in the search bar.

Could my old IP be cached and shown even after I changed it?

Not with this tool. Every request carries a unique cache-busting timestamp parameter and uses cache: no-store, so no browser cache, CDN, or intermediate proxy can serve a stale answer. When your IP changes at the network level, the tool sees it on the next request.

Why does my IP show a different city than where I live?

Three common reasons. If you are on a VPN, the exit node is somewhere else entirely. If you are on a mobile network (4G, 5G), the carrier often routes all traffic through a small number of data centres, so the IP location is the data centre, not you. If you are on a large national ISP, they may register a single range under their head office address in another city.

What is the difference between Cloudflare and Google resolvers?

That comparison belongs to the DNS tool, not this one. This IP lookup uses ipwho.is, a free, public IP geolocation API that requires no account or API key. The request goes directly from your browser to ipwho.is and never touches our servers.

Is this IP lookup free, and do I need to sign up?

Completely free, no sign-up, no email, no daily limit for normal use. The tool queries ipwho.is, a free public IP geolocation API that requires no account or API key. No ads block the input box, and nothing about your query is stored on our servers.

Is my IP address logged anywhere?

The tool itself stores nothing on our servers, the request goes directly from your browser to ipwho.is. Their API is subject to their own privacy policy, which you can review on their website. The recent lookups list shown in the tool is stored in your browser's localStorage only and never leaves your device.

How accurate is the location?

Country is almost always correct. Region is usually correct. City is best-effort, often right for residential broadband but frequently wrong for mobile networks, VPNs, corporate networks, and large national ISPs. IP geolocation is based on where the ISP registered the address range, not on where the device physically is. Accuracy at city level is typically 50 to 90% depending on the country and connection type.

Can this tool find where a specific person is?

No, and no IP-based tool can. IP geolocation maps addresses to ISPs, not to people. It can tell you which city or region an ISP registered a range in, but identifying a specific individual requires a legal process served on the ISP. Anyone who tells you they can find a person's home address from an IP is exaggerating.

What is an ASN?

ASN stands for Autonomous System Number. It is a globally unique identifier assigned to an organisation that controls a block of IP addresses and a set of routing policies, usually an ISP, a hosting company, a cloud provider, or a large enterprise. ASN 15169 is Google, AS13335 is Cloudflare, AS16509 is Amazon AWS. Seeing the ASN tells you a lot about what kind of network the IP belongs to.

Does it work with IPv6?

Yes. Both IPv4 and IPv6 addresses are supported. If you are on a modern mobile or fibre connection, you may find that your public IP is IPv6. The tool shows the type explicitly (IPv4 or IPv6) so you know which you are looking at.

Can I look up a domain name directly?

Yes. Enter any domain, google.com, cloudflare.com, your own website, and the tool resolves it and returns the same information set as for an IP: location, ISP, ASN, timezone. Useful for quickly seeing which country a site is hosted in and which hosting provider they use.

Why does my IP change every time I check?

Most consumer ISPs assign IP addresses dynamically. You keep the same IP while your router stays connected, but if it reconnects after a power cut, firmware update, or an ISP-side session timeout, you may get a different address. Mobile networks rotate IPs more frequently, sometimes every few minutes, because you are sharing a pool of addresses with other subscribers. VPNs also rotate exit IPs.

Is it legal to look up someone else's IP address?

Yes. Looking up an IP address against a public geolocation API is legal everywhere it matters, the information comes from public registry databases and is not personal data in most jurisdictions. What you do with the information matters: it is fine for security investigation, abuse reporting and network diagnostics. Using it to target or harass someone is not.

Where the data goes

The lookup request goes directly from your browser to ipwho.is, a public IP geolocation API. No account, no API key, no cookie. Every request is cache-busted with a unique timestamp so you never see a stale IP. The recent lookups list shown above is stored in your browser's localStorage only and never leaves your device.
