Enabling IP6 in existing droplet?

I am following this tutorial to enable IP6 in my existing droplet.I manage to enable the IP6 but for the configuration part when I run the command,

sudo nano /etc/network/interfaces

the output is(in the Putty),

"# This file describes the network interfaces available on your system

and how to activate them. For more information, see interfaces(5).

The loopback network interface

auto lo iface lo inet loopback

source /etc/network/interfaces.d/*"

this is not what it is shown in the tutorial,so the question is am I using the wrong command(I am a Window user so I am using Putty and also using Serverpilot)? and where do I insert the “primary_ipv6_address” and the “ipv6_gateway”?

Thank you.

What you see in the /etc/network/interfaces file is correct. You are not running any wrong command. Existing contents of the /etc/network/interfaces file is not captured in the tutorial.

Recommendation in the tutorial is to append the following block of code to your existing /etc/network/interfaces file.

iface eth0 inet6 static
       address primary_ipv6_address
       netmask 64
       gateway ipv6_gateway
       autoconf 0
       dns-nameservers 2001:4860:4860::8844 2001:4860:4860::8888

primary_ipv6_address and the ipv6_gateway should be replaced with the IPv6 address and the IPv6 Gateway that you see for your Droplet in the Droplet Network View.

Make sure to save the edits to /etc/network/interfaces before rebooting the Droplet.
