Understanding Jmdns

Jmdns Classes

There are two main classes, JmDNS and JmmDNS. The first ties services to a single address. This is fine if you have a really simple embedded app where you know the interface is always going to be there and is always up.

The difficulty with robots (and smart phones), is that the service is often going to drop in and out and may on some systems you may have multiple interfaces. Thats where JmmDNS comes in - it allows you to react to services on interface triggers (i.e. when they come up and down).
