Do you mean that the only copy of their address book was inside their cell phone? If that is the case, they will indeed have a hard time retrieving all these numbers. On the other hand, there are many ways to synchronize a cell phone with a PC or a server that keeps a safe copy. You can even use vCards (RFC2426) do describe these entries in a standardized way. > I have seen users (including myself) exchanging phone numbers in > ridiculous ways.

Not to mention publishing it in a web page, or make it available to your friends in an instant-messaging service. The problems that you describe hardly seem related to server-less name resolution in a local network! -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
