## IPv4歸屬地  > IPv4歸屬地是將網絡空間地圖測繪技術與人工智能(AI）算法相結合，利用動態密度聚類算法和基于多層神經網絡的IP地址定位算法，完成IP地址地理位置定位。IPv4歸屬地數據接口是IP地址定位數據庫的在線調用接口，分為高精準-公安版、高精準-商業版、區縣級、城市級共4個版本類型，能夠滿足客戶不同定位精度的需求。 ## 版本區別  ## 應用領域 ### 網絡安全 1. 互聯網攻防定位 2. 嫌疑人溯源跟蹤 3. 日志審計 4. 危險情報態勢感知 ### 業務安全 1. 互聯網征信位置核驗 2. 互聯網在線廣告反作弊 3. 重點辦公網絡資產普查 4. 金融信貸風險控制審查 5. 交易支付反欺詐、反薅羊毛 ### 精準營銷 1. 互聯網廣告精準投放 2. 互聯網廣告智能推薦 3. 用戶位置信息畫像 4. 渠道流量反作弊 ### 網絡優化 1. 用戶分布區域畫像分析 2. CDN節點資源布局 3. 網絡流量調度支持 4. 精準識別網絡流量地域 ## 接口調用（[調用須知](https://docs.topthink.com/think-api/1835086)） ## 接口1：高精準公安版 （ [點擊購買](https://market.topthink.com/product/484)） ### 接口費用 > 最低 0.15元/次 > ### 請求地址 ``` GET https://api.topthink.com/ip/police ``` ### 請求參數 | 名稱 | 必填 | 類型 | 示例值 | 描述 | | --- | --- | --- | --- | --- | | appCode| 是|string| |用戶授權碼，參考[API調用](https://docs.topthink.com/think-api/1835086) | | ip | 是 | String | 166.111.4.100 | 查詢的IP | | coordsys | 否 | String | WGS84 | 坐標系，分為WGS84和BD09，默認為WGS84 | | area | 否 | String | multi | 區域類型，分為multi和single，默認為multi | ### 返回`data`參數 參考返回示例 ## SDK調用 ``` $client = new Client("YourAppCode"); $result = $client->ipPolice() ->withIp('166.111.4.100') ->request(); ``` 返回示例： ~~~ { "code":0, "message": "成功", "data": { "multiAreas": { "address":"", "lat":"40.009424", "lng":"116.332556", "radius":"105.2321", "prov":"北京市", "city":"北京市", "district":"海淀區", } "continent":"亞洲", "country":"中國", "consistency":"2", "correctness":"3", "owner":"imported inetnum object for IIINT", "isp": "China Education and Research Network Center,Tsinghua University,Beijing 100084", "zipcode":"100038", "timezone":"UTC+8", "accuracy":"城市", "source":"數據挖掘", "areacode":"CN", "asnumber":"4538", } } ~~~ ## 接口2：高精準商業版（ [點擊購買](https://market.topthink.com/product/424)） ### 接口費用 > 最低 0.048元/次 > ### 請求地址 ``` GET https://api.topthink.com/ip/street ``` ### 請求參數 | 名稱 | 必填 | 類型 | 示例值 | 描述 | | --- | --- | --- | --- | --- | | appCode| 是|string| |用戶授權碼，參考[API調用](https://docs.topthink.com/think-api/1835086) | | ip | 是 | String | 166.111.4.100 | 查詢的IP | | coordsys | 否 | String | WGS84 | 坐標系，分為WGS84和BD09，默認為WGS84 | | area | 否 | String | multi | 區域類型，分為multi和single，默認為multi | ### 返回`data`參數 參考返回示例 ## SDK調用 ``` $client = new Client("YourAppCode"); $result = $client->ipStreet() ->withIp('166.111.4.100') ->request(); ``` 返回示例： ~~~ { "code":0, "message": "成功", "data": { "multiAreas": { "address":"", "lat":"40.009424", "lng":"116.332556", "radius":"105.2321", "prov":"北京市", "city":"北京市", "district":"海淀區", } "continent":"亞洲", "country":"中國", "consistency":"2", "correctness":"3", "owner":"imported inetnum object for IIINT", "isp": "China Education and Research Network Center,Tsinghua University,Beijing 100084", "zipcode":"100038", "timezone":"UTC+8", "accuracy":"城市", "source":"數據挖掘", "areacode":"CN", "asnumber":"4538", } } ~~~ ## 接口3：區縣級（ [點擊購買](https://market.topthink.com/product/425)） ### 接口費用 > 最低 0.001元/次 > ### 請求地址 ``` GET https://api.topthink.com/ip/district ``` ### 請求參數 | 名稱 | 必填 | 類型 | 示例值 | 描述 | | --- | --- | --- | --- | --- | | appCode| 是|string| |用戶授權碼，參考[API調用](https://docs.topthink.com/think-api/1835086) | | ip | 是 | String | 166.111.4.100 | 查詢的IP | | coordsys | 否 | String | WGS84 | 坐標系，分為WGS84和BD09，默認為WGS84 | ### 返回`data`參數 參考返回示例 ## SDK調用 ``` $client = new Client("YourAppCode"); $result = $client->IpDistrict() ->withIp('166.111.4.100') ->request(); ``` 返回示例： ~~~ { "code":0, "message": "成功", "data": { "continent":"亞洲", "country":"中國", "owner":"imported inetnum object for IIINT", "isp": "China Education and Research Network Center,Tsinghua University,Beijing 100084", "zipcode":"100038", "timezone":"UTC+8", "accuracy":"城市", "source":"數據挖掘", "areacode":"CN", "adcode":"110100", "asnumber":"4538", "lat":"40.009424", "lng":"116.332556", "radius":"105.2321", "prov":"北京市", "city":"北京市", "district":"東城區", } } ~~~ ## 接口4：城市級（ [點擊購買](https://market.topthink.com/product/485)） ### 接口費用 > 最低 0.0008元/次 > ### 請求地址 ``` GET https://api.topthink.com/ip/city ``` ### 請求參數 | 名稱 | 必填 | 類型 | 示例值 | 描述 | | --- | --- | --- | --- | --- | | appCode| 是|string| |用戶授權碼，參考[API調用](https://docs.topthink.com/think-api/1835086) | | ip | 是 | String | 166.111.4.100 | 查詢的IP | | coordsys | 否 | String | WGS84 | 坐標系，分為WGS84和BD09，默認為WGS84 | ### 返回`data`參數 參考返回示例 ## SDK調用 ``` $client = new Client("YourAppCode"); $result = $client->ipCity() ->withIp('166.111.4.100') ->request(); ``` 返回示例： ~~~ { "code":0, "message": "成功", "data": { "continent":"亞洲", "country":"中國", "owner":"imported inetnum object for IIINT", "isp": "China Education and Research Network Center,Tsinghua University,Beijing 100084", "zipcode":"100038", "timezone":"UTC+8", "accuracy":"城市", "source":"數據挖掘", "areacode":"CN", "adcode":"110100", "asnumber":"4538", "lat":"40.009424", "lng":"116.332556", "radius":"105.2321", "prov":"北京市", "city":"北京市", } } ~~~
