IP Geolocation API .NET SDK


Overview

The official .NET Library (C# SDK) for IPGeolocation.io's set of APIs, provides a quick, developer friendly, way to access IP Location, Security, Timezone, Astronomy, ASN, Abuse Contact, and useragent data. Lookup your own IP or provide any IPv4, IPv6 or domain name to get structured results in C#, without the need for manual handling HTTP clients, serialization, or authentication.

  • IP Location API: Get all-in-one unified solution for location (city, locality, state, country, etc.), currency, network (AS number, ASN name, organization, asn type, date of allocation, company/ISP name, company type, company domain), timezone , useragent string parsing, security (threat score, is_tor, is_bot, proxy_provider, cloud_provider), and abuse contact (route/CIDR network, country, address, email, phone numbers) information.
  • IP Security API: Get security, network, location, hostname, timezone and useragent parsing.
  • ASN API: Get ASN details along with peers, upstreams, downstreams, routes, and raw WHOIS.
  • Abuse Contact API: Get abuse emails, phone numbers, kind, organization, route/CIDR network and country.
  • Astronomy API: Get sunrise, sunset, moonrise, moonset, moon phases with precise twilight period times in combination with location information.
  • Timezone API: Get timezone name, multiple time formats, daylight saving status and its details along with location information.
  • Timezone Convert API: Convert time between timezone names, geo coordinates, location addresses, IATA codes, ICAO codes, or UN/LOCODE.
  • User Agent API: Get browser, Operating System, and device info from single or multiple Useragent string parsing.

This library aims to empower developers to integrate threat intelligence, personalization, fraud prevention, compliance, and analytics features directly into .NET applications. Whether you're enriching signup forms with ip geolocation data, localizing content, embedding threat intelligence, or converting time zones for distributed systems, the library provides a high-performance, scalable implementation leveraging .NET's modern HTTP stack and async programming model.

Authentication Setup

You’ll need an API key from ipgeolocation.io.


1.How to Get Your API Key

  1. Sign up here: https://app.ipgeolocation.io/signup
  2. (optional) Verify your email, if you signed up using email.
  3. Log in to your account: https://app.ipgeolocation.io/login
  4. After logging in, navigate to your Dashboard to find your API key: https://app.ipgeolocation.io/dashboard


2.ApiKeyAuth

Once you've obtained the api key, authenticate globally via dependency injection:


IP Geolocation Examples

This section demonstrates usage of the GetIpGeolocationAsync method from the SDK across Free, Standard, and Advanced subscription tiers. You can customize the request using parameters like fields , include , and excludes .

Parameters

  • fields : Use this parameter to include specific fields in the response.
  • excludes : Use this parameter to omit specific fields from the response.
  • include : Use this parameter to add optional modules to the response, such as:
    • security
    • user_agent
    • hostname
    • liveHostname
    • hostnameFallbackLive
    • abuse
    • dma
    • time_zone

For full API details, refer to the IP Geolocation API Documentation

The ip parameter in the SDK can accept any valid IPv4 address, IPv6 address, or domain name. If the ip parameter is omitted, the API will return information about the public IP address of the device or server where the SDK is executed.

c.Include Hostname, Timezone, and User-Agent

Sample Response:

Note

The IP Geolocation API supports hostname lookup for all paid subscriptions. However, this is not included by default. To enable hostname resolution, use the include parameter with one of the following options:

  • hostname : Performs a quick lookup using the internal hostname database. If no match is found, the IP is returned as-is. This is fast but may produce incomplete results.
  • liveHostname : Queries live sources for accurate hostname resolution. This may increase response time.
  • hostnameFallbackLive : Attempts the internal database first, and falls back to live sources if no result is found. This option provides a balance of speed and reliability.

3.Advanced Plan Example

a.Include DMA, Abuse, and Security Modules

Sample Response:

These examples demonstrate typical usage of the IP Geolocation API with different subscription tiers. Use fields to specify exactly which data to receive, include for optional data like security and user agent, and excludes to omit specific keys from the response.

Note

All features available in the Free plan are also included in the Standard and Advanced plans. Similarly, all features of the Standard plan are available in the Advanced plan.
