It doesn't matter for me, It is just a way to get a different outbound IPv6 address depending on which port the connection is made to, and both clients and servers has IPv6.
I saw a few threads here asking for more or less the same thing except that I'm specifying the full address instead of implicit addressing to the outbound, this is where I'm stuck.

The NIC is a network card if I understood it right. The IPv6 /64 subnet is added to the main interface and the gateway is aswell, IPv6 is fully working on the server.

I really don't know what I should do then... My network knowledges is somewhat limited as you may have seen. I'd appreciate any help.

Hello,
I'm trying to bound mutiples IPv4:Port entry to a different outbound IPv6
this way:
http_port 94.xxx.xxx.204:10001 name=1
acl ip1 myportname 1
tcp_outgoing_address 2a01:xxxx:xxxx:xxxx:xxxx:xxxx:eb7c:8336 ip1
http_port 94.xxx.xxx.204:10002 name=2
acl ip2 myportname 2
tcp_outgoing_address 2a01:xxxx:xxxx:xxxx:xxxx:xxxx:096f:b369 ip2
http_port 94.xxx.xxx.204:10003 name=3
acl ip3 myportname 3
tcp_outgoing_address 2a01:xxxx:xxxx:xxxx:xxxx:xxxx:5fe0:eba8 ip3
etc.
I was not able to get it working, the cache.log is giving me (99) cannot
assign requested address and fallback to the IPv4 address as an outbound
address.
I added the full IPv6 block inside the route -6 just in case, like this:
ip -6 route add to local 2a01:xxxx:xxxx:xxxx::/64 dev lo
Squid Cache: Version 3.5.23
I coudn't find anyone having the same problem while searching around so I'm
stuck and looking to know if it's possible or not to do it this way, if yes
what am I missing ? And if not, is there a way to randomize the end part of
the last 3 blocks of a /64 and if yes how ?
Thanks!

HTTP does not work that way. It is a stateless and multiplexing
protocol. Inbound and outbound connections are independent of each other.

1) It is only possible to set an IPv6 outgoing when the server being
connected to is an IPv6 server address.
2) It is only possible for Squid to use an IP address which has been
allocated/assigned to the NIC.

FYI: the lo device is hardware restricted to one machine. It is not
globally routable.

That is a feature of your system networking stack. Has nothing to do
with Squid. Lookup "Privacy Addressing" in IPv6.
