As soon as some random website's PHP script publishes your IPv6 address, there goes your security.
Assuming your IP address will remain secret seems naive.
Also, this assumes your IP address within your /48 is randomly chosen. Common user choices (or router implementations) might not default to random choices, or the randomness might not actually be very random.
- nickzoic 14y ago... for example if the IPv6 address is autoconfed from the MAC address, then you can exploit the structure of the MAC address to target a much smaller range of address suffixes, specific to the manufacturer of your target device(s).
