I have been using cloud on microtik and works very well. I have setup a new router RB951Ui-2HnD Ver 6.19. When I try to ping the DNS name it reports to an incorrect IP. When forceing it to update the DNS name will change. Forceing it again will change the name again and still pings to incorrect IP. What could be wrong?
Having the same issue

I don’t know if this is your challenge, but some busy domains (like PayPal for example) use DNS to load balance between several servers. The TTL on each domain resolution is very short, and a subsequent domain resolution request will return a different IP. PayPal uses 4 servers in the rotation last I checked with a TTL of only a couple minutes.
Take a look in “/ip dns cache” and check that domain with the IP and the TTL. If the TTL is a very short amount of time (minutes or seconds), then that may be the case.
