DigitalOcean

As the IPv6 rotation plan suggests, it is recommended to use a block size larger than /64. However, with DigitalOcean, they only provides you with 16 IPv6 addresses. If you prefer to use an IPv6 /64 or /48 block size for your DigitalOcean VPS, consider this alternative instead. Using Tunnelbroker to make Lavalink balance its requests over many IPv6 addresses

As of now, if you want to use Tunnelbroker with DigitalOcean, you might encounter a block when trying to create a tunnel for your DigitalOcean IP. You may need to contact them to unblock your server.

This how-to may depend on your system's OS, but it has already been tested on Ubuntu and Debian.

Create DigitalOcean Droplet with IPv6 enabled.

In Create Droplets panel -> Advanced Options -> Click Enable IPv6 (free)

Enable IPv6 on existed DigitalOcean Droplet.

Go to your Droplet panel -> Turn off your Droplet -> Networking -> PUBLIC IPV6 ADDRESS -> Enable -> Then turn your Droplet on again.

After you enable IPv6 on the existing Droplet, you need to configure it manually. Please refer to your OS System in this link. https://docs.digitalocean.com/products/networking/ipv6/how-to/enable/

After that, reboot your server once: reboot

Test your IPv6 connection: ping6 google.com or ping6 2001:4860:4860::8888

[Optional] use all 16 IPv6 Addresses

Please refer to your OS System in this link. How to Enable Additional IPv6 Addresses

Test your IPv6

# Don't forgot to replace IPv6 in the example with your IPv6 address.
