If you want to learn more about ipv6 you can do this free certification and they also give you a free t shirt for completing it.
badass 🤘🤘
anyways
If you want to do the certification you kind of need a VM with a public ipv4 address and a domain name. Ypu could do with some linux skills as you need to set up a simple web server and email server. I used one on hostkey, they were super helpful as they don’t allow SMTP but made an exception temporarily so I could finish the cert.
Would recommend pursuing this as it was fun. One day I will get round to dual stacking my mikrotik router at home ðŸ˜ðŸ˜‚
