Actually, your note mentions 1 (not many) issues. Morever, the issue you raise is false as stated. > IPv6 address space uses an ID > (indentifier) derived from your hardware or phone.

Seems to me that your "<censored> <censored>" is not particularly knowledgable about this issue. You might ask your source if they are familiar with RFC 3041. An IPv6 address can, in some cases, include an identifier derived from a hardware address. But this is not *required*. Moreover, there are examples where including such an identifier in an address poses no privacy issue. Servers, for instance, publish their address so that anyone can contact the server. In this case, there isn't an issue if the server address happens to contain a permanent identifier. In cases where using a permanent identifier is a problem, RFC 3041 addresses should be used. You might want to ask client vendors like Microsoft what they think of this issue (my understanding is they have already implemented RFC 3041). > Ipv6 empowers the business community by providing a means of identifying > and tracking users.
