IPGeolocationMemoryCache
IPGeolocationMemoryCache is a lightweight and efficient library designed to resolve the geolocation of an IP address using free API services. It solves the challenge of repeated API calls for high-traffic applications by caching the resolved geolocation data in memory for 10 minutes (configurable).
By utilizing this library, you can reduce API request overhead and improve the performance of your application when dealing with frequent IP geolocation lookups. It is ideal for scenarios where geolocation data is critical but maintaining low latency is equally important.
IPGeolocationMemoryCache is available using nuget. To install IPGeolocationMemoryCache, run the following command in the Package Manager Console
Install-Package IPGeolocationMemoryCache
https://www.nuget.org/packages/IPGeolocationMemoryCache
Key Features
- Free API Services Integration: Supports free IP geolocation APIs to fetch location data.
- Memory Cache: Geolocation results are cached in memory, minimizing redundant API calls.
- Configurable Cache Duration: Default cache duration is 10 minutes, but it can be easily adjusted to suit your application's needs.
- Optimized for High-Traffic: Designed for applications with high query volumes, ensuring faster response times.
- Simple Setup: Easy to integrate into existing .NET applications.
Use Cases
- Web Applications: Enhance user experiences by delivering location-based services.
- Traffic Analytics: Collect and analyze geographical data for visitor IPs efficiently.
- Fraud Detection: Quickly identify suspicious login attempts or transactions based on geolocation.
- Content Localization: Serve region-specific content with minimal latency.
How It Works
- When a request is made to resolve an IP address:
- The library first checks the in-memory cache for existing geolocation data.
- If no cached data is found, a request is sent to the configured free geolocation API.
- The response is stored in memory for the specified cache duration (default: 10 minutes).
- Subsequent requests for the same IP within the cache duration return the cached data, avoiding unnecessary API calls.
Why Choose IPGeolocationMemoryCache?
- Performance Optimization: Significantly reduces latency for geolocation queries by leveraging memory caching.
- Cost-Effective: Takes advantage of free geolocation APIs to eliminate additional costs.
- Scalability: Handles high volumes of requests seamlessly, making it suitable for demanding applications.
- Customizable: Easily adjust caching duration and configure API preferences to fit your needs.

Sample code
MemoryCache management always be done by the main application so that the cache maintained in the global context of the application.
In Program.cs add MemoryCache ServiceCollection
builder.Services.AddMemoryCache();
Create new instance of IPGeolocationMemoryCache.IpGeoLocation() with MemoryCache
using IPGeolocationMemoryCache;
using Microsoft.Extensions.Caching.Memory;
public class IpLog
{
private readonly ILogger<IpLog> _logger;
private readonly IMemoryCache _cache;
public IpLog(ILogger<IpLog> log, IMemoryCache memoryCache)
{
_logger = log;
_cache = memoryCache;
}
public void LogIPInfo()
{
string Ip = "179.162.174.33";
string host = "somehost.com";
var ipGL = new IpGeoLocation(_cache);
var ipInfo = ipGL.GetIPGeolocationAsync(Ip).Result;
var content = @$"
Host: {host} |
{ipInfo.Country} -
{ipInfo.CountryCode} -
{ipInfo.State} -
{ipInfo.City} -
{ipInfo.ISP} -
{ipInfo.Org}";
_logger.LogInformation(content.Trim());
Console.WriteLine($"{content.Trim()}");
}
}
Sample code local use
using Microsoft.Extensions.Caching.Memory;
// It is not mandatory to use the constructor with MemoryCache.
// But not using it may result in higher latency in API calls and there may be more queries than the free services allow.
public class IpInfo
{
public void GetIPGeo()
{
var _cache = new MemoryCache(new MemoryCacheOptions());
var ipGeo = new IpGeoLocation(_cache);
var lstIp = new List<string> { "179.162.174.33", "35.208.27.10", "18.217.72.66", "35.208.27.10", "179.162.174.33" };
var lstResult = new List<IIPGeolocationResult?>();
foreach (var item in lstIp)
{
lstResult.Add(ipGeo.GetIPGeolocationAsync(item).Result);
Task.Delay(3000);
}
Console.WriteLine($"1th coutry = {lstResult[0]?.Country} | 5th coutry = {lstResult[4]?.Country}");
Console.WriteLine($"2th coutry = {lstResult[2]?.Country} | 4th coutry = {lstResult[3]?.Country}");
}
}
