Notes


sbeattie

The SLP protocol was never meant to be made available to the public Internet, as the RFC 2165 authors recognize: "Service Location provides a dynamic configuration mechanism for applications in local area networks. It is not a global resolution system for the entire Internet; rather it is intended to serve enterprise networks with shared services."
