[−][src]Crate asn_db
asn-db
is a Rust library that can load and index ASN database (ip2asn-v4.tsv
file) from IPtoASN website.
Once loaded it can be used to lookup an IP address for matching ASN record that contains:
- network base IP address and mask (e.g. ipnet::Ipv4Net value like
1.1.1.0/24
), - assigned AS number (e.g.
13335
), - owner country code (e.g.
US
), - owner information (e.g.
CLOUDFLARENET - Cloudflare, Inc.
).
Example
Load database from ip2asn-v4.tsv
file and lookup 1.1.1.1
IP address.
use asn_db::Db; use std::fs::File; use std::io::BufReader; let db = Db::form_tsv(BufReader::new(File::open("ip2asn-v4.tsv").unwrap())).unwrap(); let record = db.lookup("1.1.1.1".parse().unwrap()).unwrap(); println!("{:#?}", record); println!("{:#?}", record.network());
This prints:
Record {
ip: 16843008,
prefix_len: 24,
as_number: 13335,
country: "US",
owner: "CLOUDFLARENET - Cloudflare, Inc."
}
1.1.1.0/24
Usage
Use Db::from_tsv(input)
to load database from ip2asn-v4.tsv
data.
You can then use db.store(output)
to store the binary encoded data index for fast loading with Db::load(input)
.
Use db.lookup(ip)
to lookup for matching record by an IP address.
