IP Lookup & Geolocation
Country, city, ISP, ASN and time zone for any IP address. Runs in your browser.
About this ip lookup & geolocation
This IP lookup tells you where an IPv4 or IPv6 address is on the map and who runs the network behind it: country, region, city, ISP, ASN, time zone and approximate coordinates. It is for anyone reading server logs, checking a suspicious login, or wondering where traffic comes from.
Type an address or a domain name, or press My IP to check your own. Private, reserved and documentation ranges are recognised right on the page, with the RFC that reserves them, so a 192.168.x.x or 10.x.x.x address never gets sent anywhere. Want just your own address and nothing else? What is my IP shows it without any third party.
Every lookup outside those ranges is a request to an outside database, and the page names it before you press the button. You can switch providers or compare two of them side by side, which is the quickest way to see how much IP location data can disagree.
Features
Location and network in one view
Country with flag and ISO code, region, city, postal code, coordinates, time zone with the current local time there, ISP, organisation, ASN and the network's domain.
Two databases, compared
Pick ipwho.is or GeoJS, or Compare both. When both return coordinates, the tool works out how many kilometres apart they place the address.
Bogon and private ranges detected locally
Addresses in RFC 1918 private space, carrier-grade NAT (RFC 6598), loopback, link-local, multicast, documentation and the rest of the IANA special-purpose registries are explained without a request.
Domains work too
Type a hostname such as example.com and it is resolved to its first A record (or AAAA) with Cloudflare DNS, then located. The page tells you it did that.
Map link without tracking
Coordinates open in OpenStreetMap in a new tab. No map is embedded, so no map provider sees your visit until you click.
How to use the ip lookup & geolocation
- 1Type an IP address or domain, or press My IP.
- 2Pick a data source, or Compare both to see where they disagree.
- 3Read the location, ISP and ASN, and open the spot in OpenStreetMap.
When to use it
Checking a login alert
An email says someone signed in from an unfamiliar IP. Paste it here. If the ISP is a cloud host or the city is on another continent, change your password. If it is your mobile carrier near home, it was probably you on 4G.
Reading web server logs
Find out whether a spike of requests comes from one hosting provider (an ASN like AS16509 or AS14061 is a cloud network) or from home connections around the world. Then find the network owner and abuse contact to report it.
Debugging geo-targeting
A user says your site shows the wrong currency or language. Look up their IP in both databases. If one puts them in the wrong country, that explains it, and you know which provider to ask for a correction.
How accurate is IP geolocation?
IP location is an estimate built from registry records, routing data, latency measurements and corrections that ISPs and users send in. It is not GPS. The country is usually correct. The city is often the place where your ISP's traffic enters the internet, which can be the nearest large city rather than your town.
The coordinates are the centre of the area the database believes the address belongs to. When a provider gives an accuracy radius, it is shown, and a radius of hundreds of kilometres is normal. Treat the pin as "somewhere around here", never as a street address.
- Mobile data: carriers route many regions through a few gateways, so a phone in one city may appear hundreds of kilometres away.
- VPNs and proxies: you see the exit server, which is the whole point of a VPN.
- Cloud and hosting IPs: the location is the data centre, not the person behind it.
What is an ASN, and why does it matter?
An Autonomous System Number identifies a network that runs its own routing on the internet: an ISP, a cloud provider, a university or a large company. AS15169 is Google, AS13335 is Cloudflare, AS16509 is Amazon.
The ASN is often more useful than the city. It tells you at once whether traffic comes from a home broadband network, a mobile carrier or a data centre. Click the ASN in the results to see the registry record behind it.
Which IP addresses cannot be located?
Some ranges never appear on the public internet, so there is nothing to locate. The tool checks these on the page, using the IANA special-purpose address registries:
- Private networks (RFC 1918): 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16.
- Carrier-grade NAT (RFC 6598): 100.64.0.0/10, used between your ISP and your router.
- Loopback 127.0.0.0/8 and ::1, link-local 169.254.0.0/16 and fe80::/10.
- Documentation (RFC 5737 and RFC 3849): 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24 and 2001:db8::/32.
- Unique local IPv6 fc00::/7, multicast 224.0.0.0/4 and ff00::/8, and reserved 240.0.0.0/4.
Where does the data go?
Being honest about this matters for a lookup tool. When you look up a public address, that address is sent to the provider you picked: ipwho.is or get.geojs.io. Like any website, the provider also sees your own IP as the requester. Nothing else is sent, and results are kept only in this tab's memory for ten minutes.
If you type a domain, its name is first sent to Cloudflare's DNS-over-HTTPS resolver to get an IP. For DNS work beyond that, the DNS lookup shows every record type.
Why use Mavros
| Mavros | Typical upload sites | |
|---|---|---|
| Private and bogon detection | On the page, with the RFC, no request | Sends the address and returns an error |
| Provider comparison | Two databases side by side with distance in km | One source, or a wall of ads around several |
| Map | OpenStreetMap link, nothing embedded | Embedded map with extra trackers |
| Clear about data sharing | Names each service before you look up | Rarely mentioned |
| IPv6 support | Full, including zone ids and embedded IPv4 | Often IPv4 only |
| Account or key | None | Sign-up for more than a few lookups |
Tips
- Compare both databases before you act on a city. If they disagree by hundreds of kilometres, trust only the country.
- The ASN and ISP tell you more about intent than the city. A data-centre ASN hitting your login page is rarely a real customer.
- Turn coordinates into a local time with the time zone shown. For more cities at once, use the time zone converter.
Questions
Can an IP address show my exact location?
No. An IP lookup shows an approximate area, usually the city or region of your ISP's network. Only your ISP can link an address to a subscriber's street address, and it does that for legal requests.
Why do the two databases show different cities?
Each provider builds its data differently and updates on its own schedule. Mobile networks, VPNs and recently reassigned ranges cause most disagreements.
How do I find out who owns an IP address?
Use a WHOIS (RDAP) lookup on the address. It shows the organisation the regional registry assigned the block to, plus an abuse email for reporting attacks or spam.
What does a private IP like 192.168.1.1 mean?
It is an address inside a local network, reserved by RFC 1918. Thousands of networks reuse it, so it has no public location. Your router translates it to your public IP.
Why does my IP show a different city from where I live?
Your ISP probably routes traffic through a hub in another city. That is very common for mobile data and for smaller towns served from a regional centre.
Can I look up an IPv6 address?
Yes. Any valid IPv6 address works, including compressed forms like 2001:db8::1 and addresses with a zone id. IPv4-mapped and NAT64 addresses offer a one-click lookup of the embedded IPv4.
How many lookups can I do?
Plenty for normal use. The free ipwho.is tier allows about 1,000 requests a day per network, and GeoJS publishes no limit. If one says you have hit a limit, switch to the other.
