Is there a way to figure out the country name just by looking at an IP address? I mean, do countries have specific ranges of IP addresses? For example, Australia can have IP addresses only in the range of - (just an example)

Yes, countries have specific IP address ranges as you mentioned.

For example, Australia is between 16777216 - 16777471. China is between 16777472 - 16778239. But one country may have multiple ranges. For example, Australia also has this range between 16778240 - 16779263

(These are numerical conversions of IP addresses. It depends whether you use IPv4 or IPv6)

More information about these ranges can be seen here:

We get the ip addresses of our website visitors and sometimes want to make relevant campaign for a specific country. We were using bulk conversion tools but later on decided to define the rules in an Excel file and convert it in the tool. And we have built this Excel template:

Now we use this for our own needs and also sell it. I don't want it to be a sales pitch but for those who are looking for an easy solution can benefit from this.

You could use to perform the lookup

Yes, you can download the IP address ranges by country from

You can see that each country has multiple ranges and changes frequently.

IP addresses are quite commonly used for geo-targeting i.e. customizing the content of a website by the visitor's location / country but they are not permanently associated with a country and often get re-assigned.

To accomplish what you want, you need to keep an up to date lookup to map an IP address to a country either with a database or a geolocation API. Here's an example :


United States

Or you can use the full API to get complete location for IP address e.g.

    "ip": "",
    "city": "Mountain View",
    "region": "California",
    "region_code": "CA",
    "country": "US",
    "country_name": "United States",
    "continent_code": "NA",
    "postal": "94035",
    "latitude": 37.386,
    "longitude": -122.0838,
    "timezone": "America/Los_Angeles",
    "utc_offset": "-0800",
    "country_calling_code": "+1",
    "currency": "USD",
    "languages": "en-US,es-US,haw,fr",
    "asn": "AS15169",
    "org": "Google Inc."

Amazon's CloudFront content delivery network can now be configured to pass this information through as a header. Given Amazon's size (they're big and stable, not going anywhere) and this is configuration over code (no third-party API to learn or code to maintain), all around believe this to be the best option.

If you do not use AWS CloudFront, I'd look into seeing if your CDN has a similar header option that can be turned on. Usually the large providers are quick to push for feature parity. And if you are not using a CDN, you could put CloudFront in front of your infrastructure and simply set the origin to resolve to whatever you are currently using.

Additionally, it also makes sense to resolve this at the CDN level. Your CDN is already having to figure out geo location to route the user to the nearest content node, might as well pass this information along and not figure it out twice through a third party API (this becomes chokepoint for your app, waiting for a geo location lookup to resolve). No need to do this work twice (and the second time, arguably less resilient [e.g., 3rd party geo lookup]).

Geo-Targeting – CloudFront will detect the user’s country of origin and pass along the county code to you in the CloudFront-Viewer-Country header. You can use this information to customize your responses without having to use URLs that are specific to each country.

@Andrey E 2017-08-06 20:41:17

You can try using - geo location api that returns country among other IP information.

For example with Node.js

const request = require('request-promise')

  .then(response => console.log(JSON.parse(response)))
  .catch(err => console.log(err))

@Chris Gessler 2012-03-21 10:10:44

I think what you're looking for is an IP Geolocation database or service provider. There are many out there and some are free (get what you pay for).

Although I haven't used this service before, it claims to be in real-time.

But just do a google search on IP geo and you'll get more results than you need.

I agree with above answers, the best way to get country from ip address is Maxmind.

If you want to write code in java, you might want to use i.e. geoip-api-1.2.10.jar and geoIP dat files (GeoIPCity.dat), which can be found via google.

Following code may be useful for you to get almost all information related to location, I am also using the same code.

public static String getGeoDetailsUsingMaxmind(String ipAddress, String desiredValue) 
        Location getLocation;
        String returnString = "";
            String geoIPCity_datFile = System.getenv("AUTOMATION_HOME").concat("/tpt/GeoIP/GeoIPCity.dat");
            LookupService isp = new LookupService(geoIPCity_datFile);
            getLocation = isp.getLocation(ipAddress);

            //Getting all location details 
            if(desiredValue.equalsIgnoreCase("latitude") || desiredValue.equalsIgnoreCase("lat"))
                returnString = String.valueOf(getLocation.latitude);
            else if(desiredValue.equalsIgnoreCase("longitude") || desiredValue.equalsIgnoreCase("lon"))
                returnString = String.valueOf(getLocation.longitude);
            else if(desiredValue.equalsIgnoreCase("countrycode") || desiredValue.equalsIgnoreCase("country"))
                returnString = getLocation.countryCode;
            else if(desiredValue.equalsIgnoreCase("countryname"))
                returnString = getLocation.countryName;
            else if(desiredValue.equalsIgnoreCase("region"))
                returnString = getLocation.region;
            else if(desiredValue.equalsIgnoreCase("metro"))
                returnString = String.valueOf(getLocation.metro_code);
            else if(desiredValue.equalsIgnoreCase("city"))
                returnString =;
            else if(desiredValue.equalsIgnoreCase("zip") || desiredValue.equalsIgnoreCase("postalcode"))
                returnString = getLocation.postalCode;
                returnString = "";
                System.out.println("There is no value found for parameter: "+desiredValue);

            System.out.println("Value of: "+desiredValue + " is: "+returnString + " for ip address: "+ipAddress);
        catch (Exception e) 
            System.out.println("Exception occured while getting details from max mind. " + e);
            return returnString;

sure it works in android...?

@Ben Dowling 2014-08-07 06:39:45

No you can't - IP addresses get reallocated and reassigned from time to time, so the mapping of IP to location will also change over time.

If you want to find out the location that an IP address currently maps to you can either download a geolocation database, such as GeoLite from MaxMind, or use an API like (my own service) which will also give you additional details:

$ curl
  "ip": "",
  "hostname": "",
  "loc": "37.385999999999996,-122.0838",
  "org": "AS15169 Google Inc.",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "phone": 650

It's not that easy. IP adresses are not assigned to countries as such, but to companies and organizations.

But maybe this can help you out:
