如何从IP地址整数值获取位置详细信息

Question

I am converting IP address in to its corresponding number. Now I want to know the location details ie long and lat, time zone etc. Is it possible in Java. Do i have to use some external jar for database ?

Answer 1

IP addresses themselves don't have location info. However a number of databases/services exist that have this mapping.

See this blog entry for a number of different options. There are a number of APIs and databases to connect to for this, and you have the option of downloading such info locally to avoid remote lookups.

Answer 2

So as others have correctly pointed out an IP address does not contain any of this 'metadata' about location. You will need to either rely on a third party to get this information, retrieve this information yourself, or go without it. Writing the library to scrape that information should be possible in Java.

Answer 3

  ipAddress = request.getRemoteAddr();
  GeoLocation gl = new GeoLocation();
  gl.GetGeoLocationByIP(ipAddress);

String country = gl.Country;

Answer 4

For getting location from IP address you have to buy the IP databases where they will periodically update the IP table.

However if you want, you can get the location details viz city,region,country,longitude,latitude from request header.

It's only available for GAE user.

For more details go through GAE ReleaseNotes

public static HashMap<String, Object> getLocationDetails(HttpServletRequest request)
{
    HashMap<String, Object> locationMap =   null; 
    String country  =   "",city="",region="",latitude="",longitude="",temp="",state="",title="",address="",zip="";
    boolean primary =   true;
    try
    {
        locationMap = new HashMap<String, Object>();
        country     =   request.getHeader("X-AppEngine-Country"); 
        region      =   request.getHeader("X-AppEngine-Region");
        city        =   request.getHeader("X-AppEngine-City");
        temp        =   request.getHeader("X-AppEngine-CityLatLong");
        latitude    =   (temp.split(","))[0];
        longitude   =   (temp.split(","))[1];
        log.info("country>>"+country+"region>>"+region+"city>>"+city+"temp>>"+temp+"latitude>>"+latitude+"longitude>>"+longitude);

        locationMap.put("city"      , city);
        locationMap.put("state"     , region);
        locationMap.put("country"   , country);
        locationMap.put("latitude"  , latitude);
        locationMap.put("longitude" , longitude);
        log.info("locationMap==>"+locationMap);
    }catch (Exception e) 
    {
        log.log(Level.SEVERE,"Exception while getting location"+e.getMessage(),e);
    }
    return locationMap;
}

Answer 5

you can get address of your service provider. Not the owner of phone.

if you r using android which is GPS enabled. then u can get your exact position. Code for that is given below link.

What is the simplest and most robust way to get the user's current location on Android?

Answer 6

You can use my API to lookup this information, https://ipinfo.io . If you don't pass in an IP address it'll give you details for your own one, or you can pass an IP address to get details for that one:

$ curl ipinfo.io/24.6.61.239
{
  "ip": "24.6.61.239",
  "hostname": "c-24-6-61-239.hsd1.ca.comcast.net",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "loc": "37.3845,-122.0881",
  "org": "AS7922 Comcast Cable Communications, LLC",
  "postal": "94040"
}
