IF I add to Address List ddns record. Example mikrotik.ddns.com. It creates automatically address list - with ip of ddns. The question is If the next day i change my ip how and would mikrotik resolve new ip to Address List from ddns record or i need to use script enable disable .
Address list record below:::
*.ddns.com... 0.0.0.0 mar/20/2018 15:21:21
164 DDNS *.ddns.com mar/20/2018 15:21:43
165 D ;;; *.ddns.com
DDNS 217.34.23.124(ddns ip for example) mar/20/2018 15:21:43

Thanks for help

If memory serves me well, it will look for changes every 5 minutes automatically

No, it checks the TTL of the DNS record returned and it will use that as the resolve interval.
I don't know what TTL ddns uses on their DNS but when it is 5 minutes, it will be resolved every 5 minutes,
when it is 1 hour it will be resolved once an hour.

Yes.It's 5 min TTL.you can check TTL by host -v -t a ddns(dns)name.Thnks for help
