IPinfo IPinfo Rust Client Library

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

  • IP Geolocation (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 following to your Cargo.toml file.

ipinfo = "2.2.0"

Getting Started

An access token is required, which can be acquired by signing up for a free account at https://ipinfo.io/signup.

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 https://ipinfo.io/pricing.


There are several ready-to-run examples located in the /examples directory. These can be run directly, replacing <token> with your access token

cargo run --example lookup -- <token>
cargo run --example lookup_batch -- <token>
cargo run --example get_map

The lookup example above looks more or less like

use ipinfo::{IpInfo, IpInfoConfig};
async fn main() {
    let config = IpInfoConfig {
        token: Some("<token>".to_string()),

    let mut ipinfo = IpInfo::new(config)
        .expect("should construct");

    let res = ipinfo.lookup("").await;
    match res {
        Ok(r) => {
            println!("{} lookup result: {:?}", "", r);
        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.
  • Locate IPs on a World Map.


When looking up an IP address, the response includes country_name which is the country name based on American English, is_eu which returns true if the country is a member of the European Union (EU), country_flag which includes the emoji and Unicode of a country's flag, country_currency which includes the code and symbol of a country's currency, country_flag_url which returns a public link to the country's flag image as an SVG which can be used anywhere. and continent which includes the code and name of the continent.

let r = ipinfo.lookup("");
println!("{}: {}", "", r.country_name) // United States
println!("{}: {:?}", "", r.is_eu) // Some(false)
println!("{}: {:?}", "", r.country_flag) // Some(CountryFlag { emoji: "πŸ‡ΊπŸ‡Έ", unicode: "U+1F1FA U+1F1F8" })
println!("{}: {:?}", "", r.country_flag_url) // Some(https://cdn.ipinfo.io/static/images/countries-flags/US.svg)
println!("{}: {:?}", "", r.country_currency) // Some(CountryCurrency { code: "USD", symbol: "$" })
println!("{}: {:?}", "", r.continent) // Some(Continent { code: "NA", name: "North America" })

It is possible to return the country name in other languages, change the EU countries and change the flag emoji or unicode by setting the paths of countries_file_path, eu_file_path, country_flags_file_path, country_currencies_file_path and continents_file_path when creating the IPinfo client.

The files must be .json files with structures matching the following:

let config = IpInfoConfig {
    countries_file_path: Some("custom.json".to_string()),
    eu_file_path: Some("custom_eu.json".to_string()),

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.
