IP2Country

Local lightning fast IP Address to Country lookups via Sql Server

Usage

1. Download the dbip-country.csv file from https://db-ip.com/db/#downloads (it's free) This contains the mapping between the IP Address blocks and their countries.

2. Add the file to Your Azure Storage account. You'll need to update the App_Start\Ip2CountryStartup.cs file with:

• Your account name
• Your API key
• The container name you placed the file in
• The filename

3. Add the following table to your Sql Server database:

    CREATE TABLE IpRecords
    (
        StartAddress VARBINARY(16) NOT NULL CONSTRAINT PK_IpRecords_StartAddress PRIMARY KEY,
        EndAddress VARBINARY(16) NOT NULL,
        CountryCode CHAR(2) NOT NULL
    )
   

4. Test it out! May I recommend the following test action:

    public ActionResult TestIPLookup(string ip)
    {
        var result = IpLookup.Current.GetCountryFromIp(ip);
   
        return Json(new
        {
            CountryCode = result,
            CountryName = new RegionInfo(result).DisplayName
        }, JsonRequestBehavior.AllowGet);
    }
   

Under the hood

When your application starts, the library will attempt to access the database and check for existing records. If none are found it:

• Downloads the csv file from Azure Storage
• Converts the IP Addresses to IP6 compatible Binary format
• Stores them in the database
