Tutorial

Assuming you already have an entire IPv6 subnet routed to your server, for me I purchased Vultr's server to get one.

Get your IPv6 subnet prefix, for me is 2001:19f0:6001:48e4::/64.

$ ip a
......
2: enp1s0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc fq state UP group default qlen 1000
    ......
    inet6 2001:19f0:6001:48e4:5400:3ff:fefa:a71d/64 scope global dynamic mngtmpaddr 
       valid_lft 2591171sec preferred_lft 603971sec
    ......

Bind the whole IPv6 /64 subnet to loopback interface, and add route via default internet interface

ip add add local 2001:19f0:6001:48e4::/64 dev lo
ip route add local 2001:19f0:6001:48e4::/64 dev enp1s0

Open ip_nonlocal_bind for binding any IP address:

sysctl net.ipv6.ip_nonlocal_bind=1

For IPv6 NDP, install ndppd:

apt install ndppd

then edit /etc/ndppd.conf:

route-ttl 30000

proxy eth0 {
    router no
    timeout 500
    ttl 30000

    rule 2001:19f0:6001:48e4::/64 {
        static
    }
}

Now you can test by using curl:

$ curl --interface 2001:19f0:6001:48e4::1 ipv6.ip.sb
2001:19f0:6001:48e4::1

$ curl --interface 2001:19f0:6001:48e4::2 ipv6.ip.sb
2001:19f0:6001:48e4::2

Great!

Finally, use the http proxy provided by this project:

$ while true; do curl -x http://127.0.0.1:51080 ipv6.ip.sb; done
2001:19f0:6001:48e4:971e:f12c:e2e7:d92a
2001:19f0:6001:48e4:6d1c:90fe:ee79:1123
2001:19f0:6001:48e4:f7b9:b506:99d7:1be9
2001:19f0:6001:48e4:a06a:393b:e82f:bffc
2001:19f0:6001:48e4:245f:8272:2dfb:72ce

2001:19f0:6001:48e4:be6b:6a62:f8f7:a14d
2001:19f0:6001:48e4:b598:409d:b946:17c
