如何确定一个IP地址是否属于一个国家

Question

我将如何确定一个特定IP地址源于使用C＃的国家。我需要使用它来检查连接是否源自特定的国家。

Answer 1

您可以在您的项目中使用此SQL数据来确定：IP address geolocation SQL database。下载这些数据并将其导入到数据库中以在本地运行检查。

或者您可以使用它们的免费API返回包含国家代码和国家/地区名称的XML。你会做出与IP地址，你要检查，如在这个例子中，下列URL的请求：

http://ipinfodb.com/ip_query_country.php?ip=74.125.45.100

返回：

<Response> 
<Ip>74.125.45.100</Ip> 
<Status>OK</Status> 
<CountryCode>US</CountryCode> 
<CountryName>United States</CountryName> 
</Response> 

Answer 2

如果你不想使用像hostip.info这样的API，那么我建议订阅maxmind并在本地运行一个主机查找数据库。

Answer 3

你可以要求谷歌为你做。

也有服务，您可以支付你想要的：

• http://www.ip2location.com/
• http://www.maxmind.com/

Answer 4

这里是一个免费的IP Address to Country database。

Answer 5

ip2cc - 通过IP地址查找国家和俄罗斯地区Python模块使用脚本从最新的官方数据创建数据库。

这Python实用负载（如经常只要你喜欢）了最新从Regional Internet Registry网站（arin，ripencc，apnic，lacnic，afrinic）的信息，shown in the source：

url_template = 'ftp://ftp.ripe.net/pub/stats/%s/delegated-%s-latest' 
sources = {} 
for name in ('arin', 'ripencc', 'apnic', 'lacnic', 'afrinic'): 
    sources[name] = url_template % (name, name) 

一旦数据加载，查询可以回答离线并且很快。 可以很容易地修改，直接回答原来的问题，或从命令行使用返回国家IP address属于。

Answer 6

你可以使用另一种服务是我自己的，http://ipinfo.io，它返回的位置，组织和其他信息：

$ curl ipinfo.io/8.8.8.8 
{ 
    "ip": "8.8.8.8", 
    "hostname": "google-public-dns-a.google.com", 
    "loc": "37.385999999999996,-122.0838", 
    "org": "AS15169 Google Inc.", 
    "city": "Mountain View", 
    "region": "California", 
    "country": "US", 
    "phone": 650 
}

Answer 7

只需拨打一个简单的API即可。https://ipapi.co/8.8.8.8/country/

美国

这里有一个working fiddle C＃示例：

using System; 
using System.Net; 
using System.IO; 
using System.Text; 


public class Program 
{ 
    public static void Main() 
    { 

     ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; 

     HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://ipapi.co/8.8.8.8/country/"); 
     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 

     var reader = new System.IO.StreamReader(response.GetResponseStream(), ASCIIEncoding.ASCII); 
     Console.WriteLine(reader.ReadToEnd()); 

    } 
} 

Answer 8

以下是如何与https://ipdata.co

//Common testing requirement. If you are consuming an API in a sandbox/test region, uncomment this line of code ONLY for non production uses. 
//System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; }; 

//Be sure to run "Install-Package Microsoft.Net.Http" from your nuget command line. 
using System; 
using System.Net.Http; 

var baseAddress = new Uri("https://api.ipdata.co/78.8.53.5"); 

using (var httpClient = new HttpClient{ BaseAddress = baseAddress }) 
{ 

    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("accept", "application/json"); 

    using(var response = await httpClient.GetAsync("undefined")) 
    { 

     string responseData = await response.Content.ReadAsStringAsync(); 
    } 
} 

通过卷曲

做到这一点

curl https://api.ipdata.co/78.8.53.5 
{ 
    "ip": "78.8.53.5", 
    "city": "G\u0142og\u00f3w", 
    "region": "Lower Silesia", 
    "region_code": "DS", 
    "country_name": "Poland", 
    "country_code": "PL", 
    "continent_name": "Europe", 
    "continent_code": "EU", 
    "latitude": 51.6461, 
    "longitude": 16.1678, 
    "asn": "AS12741", 
    "organisation": "Netia SA", 
    "postal": "67-200", 
    "currency": "PLN", 
    "currency_symbol": "z\u0142", 
    "calling_code": "48", 
    "flag": "https://ipdata.co/flags/pl.png", 
    "emoji_flag": "\ud83c\uddf5\ud83c\uddf1", 
    "time_zone": "Europe/Warsaw", 
    "is_eu": true, 
    "suspicious_factors": { 
     "is_tor": false 
    } 
}⏎

对于离线数据库，你可以得到免费的IP2Location LITE DB1

要创建表

CREATE DATABASE ip2location 
GO 

USE ip2location 
GO 

CREATE TABLE [ip2location].[dbo].[ip2location_db1](
    [ip_from] float NOT NULL, 
    [ip_to] float NOT NULL, 
    [country_code] nvarchar(2) NOT NULL, 
    [country_name] nvarchar(64) NOT NULL, 
) ON [PRIMARY] 
GO 

CREATE INDEX [ip_from] ON [ip2location].[dbo].[ip2location_db1]([ip_from]) ON [PRIMARY] 
GO 

CREATE INDEX [ip_to] ON [ip2location].[dbo].[ip2location_db1]([ip_to]) ON [PRIMARY] 
GO 

要导入数据

BULK INSERT [ip2location].[dbo].[ip2location_db1] 
    FROM 'C:\[path to your CSV file]\IP2LOCATION-LITE-DB1.CSV' 
    WITH 
    (
     FORMATFILE = 'C:\[path to your DB1.FMT file]\DB1.FMT' 
    ) 
GO 

对于FMT文件

10.0 
5 
1 SQLCHAR 0 1 "\"" 0 first_double_quote Latin1_General_CI_AI 
2 SQLCHAR 0 20 "\",\"" 1 ip_from "" 
3 SQLCHAR 0 20 "\",\"" 2 ip_to "" 
4 SQLCHAR 0 2 "\",\"" 3 country_code Latin1_General_CI_AI 
5 SQLCHAR 0 64 "\"\r\n" 4 country_name Latin1_General_CI_AI
