So, I followed this answer on this post and now I want to undo the changes.

How do I even know something has changed?
And if something changed, how would I undo it?

The directions you linked to state to create a file /etc/modprobe.d/blacklist-ipv6.conf containing some text which will instruct the system to never load the IPv6 kernel module.

To undo this, you simply remove the file, with sudo, and then reboot.

sudo rm /etc/modprobe.d/blacklist-ipv6.conf
sudo reboot   # Or reboot from the GUI, it doesn't matter how you reboot

Upon reboot, the kernel will be able to load the IPv6 modules, and you will then be able to configure (or autoconfigure) IPv6 on your system.
