Add IPv6 Support to dyndns.sh Script

[ethandetigris]

Thank you for the great work on dyndns.sh. I’d like to request the addition of IPv6 support to the script. In IPv6-dominant or dual-stack environments, it would be helpful to detect and update the device’s global IPv6 address alongside IPv4. Adding a parameter like --ipv6 to manage this functionality would greatly enhance the script’s versatility. Thank you for considering this feature!

I have a fork that can help address this.

The changes are in

/lambda/index.py
dyndns.sh

They will update both records for A and AAAA records in IP4/IP6 formats.

Let me know if this helps.
