Crate philiprehberger_ip_utils 

IP address utilities — CIDR matching, subnet calculation, classification, and anonymization.

This crate provides tools for working with IPv4 and IPv6 addresses using only the standard library. Features include CIDR range parsing and matching, subnet calculations, IP classification (private, loopback, CGNAT, etc.), anonymization for GDPR compliance, and CIDR aggregation.

Examples

use philiprehberger_ip_utils::{Cidr, IpClassify, anonymize};
use std::net::IpAddr;

let cidr = Cidr::parse("192.168.1.0/24").unwrap();
let ip: IpAddr = "192.168.1.100".parse().unwrap();
assert!(cidr.contains(ip));

assert!(ip.is_private());
assert!(!ip.is_global_ip());

let anon = anonymize(ip, 8);
assert_eq!(anon.to_string(), "192.168.1.0");
