NetOrigin is a small Rust project for retrieving network ownership data and IP ranges.

It can be used as:

• A CLI tool
• A reusable library crate (netorigin::ipranges)

It supports:

• Google service IP ranges from Google's published JSON feeds
• Company-to-ASN lookup via bgp.he.net
• Company-to-IP-range aggregation via bgp.he.net
• ASN-to-IP-range lookup via bgp.he.net
• IP-to-ASN ownership lookup via IPinfo

• Rust toolchain with Cargo
• Network access for live lookups
• IPINFO_TOKEN environment variable when using --ip

cargo check

cargo test

cargo run -- --google
cargo run -- --company telegram
cargo run -- --company telegram --asnums
cargo run -- --asn AS15169
cargo run -- --ip 8.8.8.8

You can also pass the ASN without the AS prefix:

cargo run -- --asn 15169

For IPinfo lookups, export a token first:

export IPINFO_TOKEN=your_token_here
cargo run -- --ip 8.8.8.8
IPinfo lookup for '8.8.8.8':
ASN: AS15169
Name: Google LLC
Domain: google.com

NetOrigin also exposes IP range functionality through a library module.

use netorigin::ipranges;

fn main() -> Result<(), Box<dyn std::error::Error>> {
	let as_numbers = ipranges::get_as_numbers_of("telegram")?;
	println!("Found {} AS numbers", as_numbers.len());

	let ip_ranges = ipranges::get_ip_ranges_for_asn("AS15169")?;
	println!("Found {} IP ranges", ip_ranges.len());

	Ok(())
}

Available library entry points include:

• get_google_ip_ranges
• get_as_numbers_of
• get_ip_ranges_of
• get_ip_ranges_for_asn
• lookup_ipinfo
• from_ipnet / to_ipnet

• The --company, --asn, and --google flows rely on public third-party endpoints and page structure.
• The --ip flow uses IPinfo and falls back from the Core lookup endpoint to the Lite endpoint when the token does not have Core access.
• Deterministic unit tests cover local parsing logic, but some tests and runtime commands still depend on live network access.

• src/lib.rs: library entry point that exports ipranges
• src/cli.rs: CLI argument parsing with clap
• src/main.rs: command dispatch and terminal output
• src/ipranges.rs: HTTP requests, scraping, IP range aggregation, and IPinfo lookup logic
