Get the codes for the representation of names of countries and regions from IP address.
Add ip2c to your Cargo.toml file
[dependencies]
ip2c = "0.1.5"You can directly use rir::IpCodeMap build IP to Codes for the representation of names of countries and regions.
use ip2c::rir::IpCodeMap;
let mut map = IpCodeMap::new();
map.load_from_dir("./data").expect("load rir txt info failed");
let code = map.query("127.0.0.1".parse().unwrap());
println!("{}", code.unwrap());this library do not provide rir information files, you need download yourself.
see example.txt about download url and official txt format.
Also, you can use IpTree to build IP city location map, eg:
use ip2c::IpTree;
let mut map = IpTree::new();
map.ipv4.insert("101.204.128.0-101.204.130.0".parse().unwrap(), ("Sichuan", "Chengdu")).unwrap();
map.ipv4.insert("43.128.148.100-200".parse().unwrap(), ("South Korea", "Seoul")).unwrap();
map.ipv4.insert("124.156.239.210".parse().unwrap(), ("Japan", "Tokyo")).unwrap();
map.ipv4.insert("123.117.21.0/24".parse().unwrap(), ("Beijing", "Beijing")).unwrap();
map.ipv4.insert("123.117.253.1/20".parse().unwrap(), ("Beijing", "Beijing")).unwrap();
assert_eq!(map.ipv4.query("101.204.129.1".parse().unwrap()), Some(&("Sichuan", "Chengdu")));
assert_eq!(map.ipv4.query("123.117.21.10".parse().unwrap()), Some(&("Beijing", "Beijing")));
assert_eq!(map.ipv4.query("208.123.10.95".parse().unwrap()), None);
