I was tinkering with IPv6 on my router and found I don’t have time to work on it right now. I disabled the IPv6 DHCP client on my hAP AC2 but for some reason the Mikrotik Cloud DNS address assigned to my router still seems to resolve to an IPv6 address in addition to my IPv4 address. This is making things difficult as some of my Android apps (my port knock app in particular) prefer IPv6. Is there any way to trigger a purge of the IPv6 entry on Mikrotik’s side?
Yes, disable IP Cloud DDNS, apply, enable, apply.
Thanks, I’ve tried this before and I tried it again and it had no effect; IP Cloud Print still produces an IPv6 result.
In case it matters, I’m running version 6.48.6.
Confirm it is not working after disable (save your IP addr).
If it doesn’t work after disable it means everything is fine and your router still has IPv6 connectivity (probably via SLAAC).
Thanks, I figured it out. I had to disable DDNS, reboot the router, then enable DDNS. Now there is no IPv6 address shown in IP Cloud Print or when I run an nslookup.
Did enter same situation.
Someone was not able to go to my webserver and after some investigation we see that he tried IPv6, that I have disabled 2 years ago.
A lookup of DNS to google and other did show both IPv4 and IPv6 ip for my Cloud name.
Just disable DDNS in cloud and enable it again did resolve the problem. IPv6 IP gone.
No reboot needed.
Thanks for information in this post.
I also ran into this issue. I think that the IPv6 should automatically be dropped from the DNS entry if the router no longer has a publicly accessible IPv6.
This lead to problems with Back To Home in my case, and I’m unable to perform the workaround in this thread, because this would require Back To Home to be disabled.
