My IP Address Checker for your public IP and connection details
Open the page and your current public IP address appears at the top straight away, followed by your ISP and location, an exposure check, browser details, and a breakdown of the address itself. After switching a VPN on or off, press Check again to refresh every value.

How to read what your IP address check is telling you
An IP address is the number that identifies your connection on the internet. When you open a site, the server on the other end reads that number to know where to send the response. That is why the question of what is my IP address comes up the moment someone needs it from you: allowlisting for remote access, asking for a block to be lifted, or registering with a game server.
The sections below explain what each value on the page means, how far you should trust it, and how the numbers shift once a VPN or a router sits in the path.
Public and private addresses are different things
The value at the top of the page is your public IP. Your ISP assigns it to your line, it is unique across the internet, and it is what every site you visit sees. An address starting with 192.168 is a private IP that your router hands out for use inside the building, and nothing outside can reach it. When someone asks for an address to open a port or add a firewall exception, they almost always mean the public one.
- Public IP — assigned by the ISP, unique on the internet
- Private IP — assigned by the router, local only
- Every device in the house shares one public IP
- Restarting the router can change the public IP
Where these values come from
Three services split the work. The public IP itself comes from ipify, the country, city, ISP and ASN come from ipwho.is, and the relay verdict comes from ipapi.is. Browser, screen, language and time zone are read on the device with no network request at all. If one source fails the rest still fill in, and the failed source is named in the status line under the buttons.
- Every lookup runs in your own browser
- ROBERIN servers never receive the result
- An ad blocker can stop the requests and leave fields empty
- Check again re-queries all three sources
Why IPv4 and IPv6 are shown together
IPv4 offers about 4.3 billion addresses and ran out years ago, which is why IPv6 exists. Both can be active at once, and which one actually carries your traffic depends on what the far end supports. When you hand someone your IP and the connection still fails, it is often because the address they see is not the one you sent.
- IPv4 — four dotted groups, e.g. 203.0.113.24
- IPv6 — eight colon-separated groups, e.g. 2001:db8::1
- With both present the browser picks per connection
- No IPv6 usually means the line or router has it turned off
How much to trust the location
Location is derived from a database that pairs ISP address ranges with places, not from GPS. Accuracy therefore varies sharply by field. Country is nearly always right, state is often right, the city is frequently a network hub rather than your town, and ZIP code and coordinates are approximate center points.
- Country — reliable
- State — usually correct
- City — may resolve to a network hub
- ZIP code and coordinates — rough center, not an address
Reading the relay verdict
The verdict matches your address against organization registrations and known VPN or hosting ranges. It is a reasoned estimate, not a certainty. A VPN can read as direct, and a corporate line can read as a datacenter. Pairing the verdict with the time zone row below makes the judgement far more reliable.
- VPN, proxy or Tor — signs of a relayed path
- Datacenter — hosting space rather than a residential line
- Abuse history — spam or attacks reported from this range
- All three are estimates based on registration data
How WebRTC leaks an internal address
WebRTC powers browser video calls and screen sharing. To find the shortest path to the other party it assembles a list of internal IP candidates, and pages used to be able to read that list directly. Because a VPN cannot hide it, browsers now substitute a random mDNS name for the internal address.
- Hidden by mDNS — default browser protection is active
- Numeric address exposed — the page can read your network layout
- Not supported — the browser has WebRTC disabled
- To lock it down further, disable WebRTC in settings or an extension
What a time zone or language mismatch reveals
VPN use is not judged from the IP alone. Your browser also reports the operating system time zone and preferred languages, and a VPN does not change either. So an IP in the United States paired with a Seoul time zone gives the relay away by itself. Real sites use exactly this combination when screening for fraud.
- IP time zone — based on the region of the connecting address
- Browser time zone — based on the device operating system
- A gap between them points to a relayed connection
- Language preferences work as the same kind of signal
Reading the address breakdown
The breakdown at the bottom takes the address apart numerically. IPv4 uses four numbers from 0 to 255, eight bits each, so 32 bits in total. The binary row lays those 32 bits out, and the integer row reads the same value as a single decimal number. The /24 network address is the block of 254 addresses that share your first three groups.
- Octets — four dotted groups of eight bits each
- Binary — the same 32 bits written out
- Integer — handy for firewall rules and sorting logs
- /24 — the block sharing your first three groups
Some ranges are reserved for special purposes
Not every IPv4 address is usable on the internet. Several blocks have fixed purposes and are never assigned as public addresses. If the address type row says anything other than public address, the value on screen is an internal one rather than a real internet address.
- 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 — private ranges
- 100.64.0.0/10 — shared between subscribers by the carrier
- 127.0.0.0/8 — loopback, pointing at the device itself
- 169.254.0.0/16 — temporary range used when no address is assigned
Finding your internal IP behind the router
This page only reports the address the outside world sees. Pointing at a device inside the building, such as a printer or a NAS, needs the internal address instead. Each system exposes it in a different place.
- Windows — run ipconfig in Command Prompt
- macOS — run ifconfig in Terminal, or open Network details in Settings
- Android — open the details of the connected Wi-Fi network
- iPhone — tap the info icon next to the Wi-Fi network
What an IP does and does not reveal
Whether an IP counts as personal data gets argued about, but the practical line is fairly clear. A site operator can learn the ISP and a rough area from an IP and no more. Which subscriber held it at a given time exists only in ISP allocation records, obtainable through legal process. Since it becomes identifying once combined with other data, treating it as personal data is the safe default.
- Visible — ISP, rough area, whether it is a datacenter
- Not visible — name, exact address, who owns the device
- ISP only — subscriber allocation at a given moment
- Combined with other data it becomes identifying
A short check before you share it
Run through this before handing your address to anyone. Sending the wrong one is a common reason allowlisting fails.
- Whether they need the IPv4 or the IPv6 address
- Whether you are currently behind a VPN or a corporate proxy
- How long a dynamic address will stay valid
- Whether you are about to post it in a public thread
When people reach for this tool
The situations that send people looking for their IP are fairly consistent.
- Requesting allowlisting for an internal system or admin panel
- Confirming a VPN is really in effect by toggling it
- Sharing a game server or remote desktop address
- Investigating a block to see whether your range is flagged
Questions about checking your IP address
My public IP keeps changing. Is something broken?
Nothing is broken. Most home connections use dynamic addressing, so the address changes whenever the router restarts or the line reconnects. A static IP is a separate product, usually sold on business lines. If you need a fixed address for remote access or a server, ask your ISP about static IP or set up dynamic DNS instead.
The city shown is not where I am.
IP location comes from a database that maps ISP address ranges to areas, not from satellite positioning. What you see is the region a line is registered to rather than where you physically are. Country is usually right, state is often right, and ZIP code or coordinates should never be treated as an actual address.
No IPv6 address is shown.
Your connection or router has not enabled IPv6. Many home lines still run IPv4 only, and even when the ISP supports IPv6 a router with the feature switched off will stop your device from getting an address. Everyday browsing is unaffected, but if you need to reach an IPv6-only service, check the router settings and your plan.
I am on a VPN but it says direct connection.
The verdict comes from matching your address against organization records and known ranges. A freshly assigned address, or one registered as residential, may not be on those lists yet and will show as direct. When that happens, look at the time zone row instead: a mismatch between your IP time zone and your browser time zone is itself evidence of a relay.
What does the WebRTC check actually test?
WebRTC, the feature behind browser video calls, builds a list of your internal IP candidates so it can find the shortest route to the other party. If a page can read that list, your private network layout is visible even with a VPN running. Modern browsers replace internal addresses with random mDNS names, and this check tells you whether that protection is actually in place.
Why can I not see my 192.168 address here?
That address is handed out by your router for use inside your home, so nothing outside can see it. Web pages cannot normally read it either, and the WebRTC row above is the one exception. To read it directly, run ipconfig in Command Prompt on Windows, ifconfig in Terminal on macOS, or open the Wi-Fi details screen on Android and iPhone.
Does this page store my IP?
It does not. The lookup runs in your browser and the result only ever reaches your screen. The IP, location and ISP data do come from external lookup services, so those requests are visible to them. The providers in use are named in the references below.
Can someone identify me from an IP address alone?
Not from the point of view of an ordinary site operator. An IP reveals the ISP and a rough area, and nothing more. Which subscriber held that address at a given moment lives only in the ISP allocation records, which require legal process to obtain. Because an IP becomes identifying once combined with other data, treating it as personal data is the safe default.
The values look wrong on my office or campus network.
Institutional networks usually put many users behind a single public IP and route traffic through security appliances. That is why the location may resolve to a head office or a datacenter, and why the datacenter verdict can trigger. Checking again from a personal connection gives a different result.
