IPData.info .NET SDK — Free IP Geolocation & Threat Intelligence API

Official .NET client for ipdata.info — a free, fast IP geolocation, ASN, and threat-intelligence API. Look up country, city, ASN, timezone, currency, and security flags (proxy/VPN/Tor/hosting) for any IPv4 or IPv6 address. Powered by ipdata.info.

Get a free API key

The public endpoint is free — 50 requests/min, no signup, no key. For higher rate limits and batch lookups, create a free API key at ipdata.info/register and manage it in your dashboard.

Install

dotnet add package IPDataInfo.Sdk

Quickstart

using IPDataInfo;

using var client = new IPDataClient(); // free tier; or new IPDataClient(apiKey: "KEY")

var info = await client.LookupAsync("8.8.8.8");
Console.WriteLine($"{info.City}, {info.Country} ({info.AsnOrg})"); // Mountain View, United States (Google LLC)

Methods

Method	What it returns
LookupAsync(ip?)	Full geolocation record (own IP if ip omitted)
GeoAsync(ip)	Geo subset (city/region/country/lat/lon/tz)
AsnAsync(ip)	ASN + ISP/registry for an IP
BatchAsync(ips)	Many IPs at once (requires an API key)
AsnDetailAsync(n)	ASN detail incl. prefixes
AsnWhoisHistoryAsync(n)	ASN whois history
AsnChangesAsync()	ASN change feed

    baseUrl: "https://ipdata.info",    // override the host
    httpClient: customHttpClient,      // bring your own HttpClient (proxy, handlers, ...)
