Actually, I'm not a fan of recommending using GUA in the case of devices that should be "discoverable by default". I was merely providing a suggestion for the definition of types of devices that should be discoverable by default. Sorry -- I should have mentioned that. So, no, I wouldn't want to say what you suggest at all. After dealing fairly extensively with such devices, I've personally come to the conclusion that it depends on the specific application and the usage model of the application. I don't think a global recommendation is possible. Barbara _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
