I have a Mikrotik router running routerOS. The router has a ddns function which connects with Micritik and updates the ip address of a particular url (like

I have seen, for example on, that you can configure the hostname with a CNAME record and no A record is created. Also, on the Mikrotic forums, posters have said that this will work with a CNAME and no A records on other ddns providers. So how would that be done, if possible?

1. Add a CNAME like 120 CNAME
2. Delete A records


PS. I know there are scripts which can run on the MT routers to update dynu ddns but it appears that the script can only update on domain at a time. I currently use ddclient and it works fine to do 3 domains at a time.
