Idea and Concept

JmDNS is a Java implementation of multi-cast DNS and can be used for service registration and discovery in local area networks. JmDNS is fully compatible with Apple's Bonjour.

The Zeroconf working group is working towards zero configuration IP networking. Multi-cast DNS and DNS service discovery provide a convient ways for devices and services to register themselves, and to discover other network-based services without relying on centrally administered services.

Java as a language is not appropriate for low-level network configuration, but it is very useful for service registration and discovery. JmDNS provides easy-to-use pure-Java mDNS implementation that runs on most JDK1.6 compatible VMs.

The code is released under the Apache 2.0 license so that it can be freely incorporated into other products and services.

History

The project was originally started in December 2002 by Arthur van Hoff at Stangeberry. In November 2003 the project was moved to SourceForge, and the name was changed from JRendezvous to JmDNS for legal reasons.
