IPinfo IPinfo Rust Client Library

This is the Rust client library for the IP address API. It allows you to lookup your own IP address, or get any of the following details for an IP:

  • GeoIP (city, region, country, postal code, latitude and longitude)
  • ASN (ISP or network operator, associated domain name, and type, such as business, hosting or company)
  • Company data (the name and domain of the business that uses the IP address)
  • Carrier details (the name of the mobile carrier and MNC and MCC for that carrier if the IP is used exclusively for mobile traffic)

Check all the data we have for your IP address here.


To use IPinfo, add the followinig to your Cargo.toml file.

ipinfo = "0.3"

Getting Started

An access token is required, which can be acquired by signing up for a free account at

The free plan is limited to 50,000 requests per month, and doesn't include some of the data fields such as the IP type and company information. To get the complete list of information on an IP address and make more requests per day see


use ipinfo::{IpInfo, IpInfoConfig};

fn main() {
  let config = IpInfoConfig { token: Some("my token".to_string()), ..Default::default() };
  let mut ipinfo = IpInfo::new(config).expect("should construct");
  let res = ipinfo.lookup(&["", ""]);

  match res {
    Ok(r) => println!("{}: {}", "", r[""].hostname),
    Err(e) => println!("error occurred: {}", &e.to_string()),


  • Smart LRU cache for cost and quota savings.
  • Structured and type checked query results.
  • Bulk IP address lookup using IPinfo batch API.

Other Libraries

There are official IPinfo client libraries available for many languages including PHP, Go, Java, Ruby, and many popular frameworks such as Django, Rails and Laravel. There are also many third party libraries and integrations available for our API.
