Stop running away from this, request and assign an IPv6 address to an external interface to make content available over both IPv4 and IPv6.
Assign an IPv6 address to an interface using ip utility.
$ ip -6 address add 2A00:0C98:2060:A000:0001:0000:1d1e:ca75/64 dev eth0
Use the same tool to configure the default route.
$ ip -6 route add default via 2A00:0C98:2060:A000:0000:0000:0000:0001 dev eth0
Ping the gateway to ensure you can reach it.
$ ping6 -c1 2A00:0C98:2060:A000:0000:0000:0000:0001

Edit /etc/network/interfaces configuration file, add an inet6 address to make it permanent.
