IP Cloud can it only update IPV6?

my Router has two IP address, one is internal ip version 4 (192.168.1.:sunglasses: and a public ip version 6 (2512:xxxx:xxxx:xxxx::1),
but the Cloud dns fuction update the name ”xxxxxxxxxx.sn.mynetname.net“ has two ip: 192.168.1.8 and 2512:xxxx:xxxx:xxxx::1,
I don’t want the internal ip update to the dns and only the ipv6 address can update to the dns,then I can access the router over ipv6.
can it have the option to set only update ipv6 to then dns server?

thank’s

That shouldn’t happen unless you’ve checked “use local address”
From the wiki: https://wiki.mikrotik.com/wiki/Manual:IP/Cloud#Advanced

use-local-address (yes | no; Default: no) By default, the DNS name will be assigned to the detected public address (from the UDP packet header). If you wish to send your “local” or “internal” IP address, then set this to yes
