[ipv6hackers] Dynamic prefixes & privacy (was: IPv6 prefix changing)

[Owen DeLong]

Not true.

Your IP public IP address is not obfuscated today and is akin to not changing (or at least not rapidly changing) prefixes in IPv6.

If you are counting on your public IPv4 address changing for privacy today, you are either suffering from a degraded network experience (most likely at the hands of a German ISP), or, you are deluding yourself.

Having a dynamic (though rarely changing) IPv6 prefix with PEA would provide roughly the same privacy as IPv4 today, which is nearly none.
