I have a newb question I'd like to ask. We have an dedicated server and we got an ipv6 /64 block.

We want to use squid to make proxy and use those IP.

And my question now is: Is it possible to use only one IP out of range? for example:

let's say I have a range of IPs ffff:ffff::/64, and want to use only one address from it: ffff:ffff::1/128 or ffff:ffff::2/128 but whenever I set squid like this I always get from 'what is my ip' services whole subnet which is again ffff:ffff::.

What I want to achieve is to get from those 'what is my ip' services to send me back IP ffff:ffff::1 (or 2 for that matter)

Am I doing something wrong?
