Commons Network

This project has been set to read-only since there is no longer an active maintainer in the organization.

A library of IP network representation classes, like

• IP address (IPv4, IPv6),
• MAC address,
• IP network using the CIDR method (Classless Inter-Domain Routing).

Prerequisites

• Java 8 or later
• Maven 3.6 or later

Design Goals

The following are the key design goals:

• Test-coverage: Have well-tested classes. Test coverage is at the moment at 95% line-coverage.
• Immutability: Have immutable classes where possible to support usage in a multi-threaded environment.
• Performance: Have simple, well-performing implementations.
• Simplicity: Have simple implementations where possible.
• No dependencies: Do not require dependencies for the core cases.
• Fail-fast: If you enter illegal data, you'll get an exception. The invariant of all objects is to contain no illegal or null data.
• No I/O: In contrast to the InetAddress class in JDK, these classes are just model classes.

Usage

You can include commons-network as a Maven dependency from Maven Central.

Maven dependency

<dependency>
    <groupId>com.oneandone</groupId>
    <artifactId>commons-network</artifactId>
    <version>0.14.0</version>
