Help - duckdns has started returning an IPv6 IP address

[jata]

Trying to work out if I need to talk to my ISP or someone else as I can no longer connect to my network from the outside using duckdns as my DDNS service.

If I ping my duckdns address from outside my network, it is returning an IPv6 address and no IPv4 address.

Is this and ISP issue?

Please ignore. Have fixed the issue by a combo of:

1. asked ISP to disable IPv6 (not the issue BTW)
2. restart router (to pick up new IP from ISP - also not the issue)
3. rebooted iPhone (I think this was the issue but not sure as I was trying everything all at once!)

Happy Easter everyone.
