Service Undiscovery Using Hide-and-Go-Seek
for the Domain Pseudonym System (DPS)
Abstract
With the ubiquitous success of service discovery techniques, curious
clients are faced with an increasing overload of service instances
and options listed when they browse for services. A typical domain
may contain web servers, remote desktop servers, printers, file
servers, video content servers, automatons, Points of Presence using
artificial intelligence, etc., all advertising their presence.
Unsurprisingly, it is expected that some protocols and services will
choose the comfort of anonymity and avoid discovery.
This memo describes a new experimental protocol for this purpose
utilizing the Domain Pseudonym System (DPS), and discusses strategies
for its successful implementation and deployment.

RFC 6593 Service Hide-and-Go-Seek 1 April 2012
1. Introduction
In today's domains, there are services that, by choice, prefer to not
be advertised and to cloak themselves with a shroud of anonymity.
However, protocols do not address the needs of these services. To
solve this, we propose a new paradigm of service hide-and-go-seek for
services that do not want to be discovered. A client may be looking
for a service, but an apathetic, playful, overwhelmed, or shy service
might prefer a hide or hint engagement, instead of directly showing
itself.
