这个IP库实测还是比较准确的,免费版的可以具体到国内城市，国外只能到国家名称,免费版的自己定期更新Ip数据库即可。
以下为C#调用代码
class Program
{
static void Main(string[] args) { try { //传入要查询的ip 和17monipdb.datx 下载的ip库所在位置 string address = IPAddress.FindIPAddress("1.198.219.205", @"D:\开发资料\资料\Code\IP地址获取\IPAddress\IPAddress\bin\Debug"); Console.WriteLine(address); } catch (IOException ioex) { Console.WriteLine(ioex.StackTrace); } catch (IPv4FormatException ipex) { Console.WriteLine(ipex.StackTrace); } Console.ReadKey(true); } } public class IPAddress { public static string FindIPAddress(string ip,string basePath) { string address = ""; if (string.IsNullOrEmpty(ip)) { return address; } try { string path = string.Format("{0}\\{1}", basePath, "17monipdb.datx"); City city = new City(path); string[] arr = city.find(ip); if (arr != null && arr.Length > 0) { address = string.Join("-", arr); } } catch (IOException ioex) { Console.WriteLine(ioex.StackTrace); } catch (IPv4FormatException ipex) { Console.WriteLine(ipex.StackTrace); } return address.TrimEnd("-".ToCharArray()); } }
