CodeLogic.NetUtils

DNSBL blacklist checking and IP geolocation services for CodeLogic applications, using MaxMind GeoIP2.

Install

dotnet add package CodeLogic.NetUtils

Quick Start

var netUtils = new NetUtilsLibrary();
// After library initialization via CodeLogic framework:

// Check if an IP is blacklisted
var result = await netUtils.Dnsbl.CheckAsync("203.0.113.1");
Console.WriteLine($"Listed: {result.IsListed}");

// Look up IP geolocation
if (netUtils.HasGeoIp)
{
    var geo = netUtils.GeoIp.Lookup("203.0.113.1");
    Console.WriteLine($"Country: {geo.Country}, City: {geo.City}");
}

Features

DNSBL checking — query multiple blacklist services (IPv4 and IPv6) with parallel lookups
IP geolocation — city-level lookups via MaxMind GeoLite2/GeoIP2 databases
Auto-update — optionally download and refresh the GeoIP database on startup
Configurable services — primary and fallback DNSBL providers per address family

# CL.NetUtils — Changelog

All notable changes to **CodeLogic.NetUtils** are documented here. Versions follow
[Semantic Versioning](https://semver.org/).

## [4.0.4] — 2026-04-16

### Changed

- README + manifest refresh for the v4 baseline. No functional changes vs 4.0.3.
- `LibraryManifest.Version` now reads from assembly metadata.

## [4.0.2] — 2026-04-09

### Added

- `DnsblCheckRequest` overload that accepts a caller-supplied DNSBL service
list — useful when the calling app stores its own service registry instead
of relying on the bundled defaults.

### Changed

- Annotated NetUtils configuration with `[ConfigField]` for the admin UI surface.
- Aligned with the v4 baseline across all libraries.

## [4.0.0] — 2026-04-09

Major rewrite. Republished as v4.0.0 to reset the version line under the
unified v4 baseline. GeoIP, DNSBL, and IP/CIDR utilities.

### Notes

- Earlier history is retained in the
[git log](https://github.com/Media2A/CodeLogic.Libs/commits/main/CL.NetUtils).
