Hi. I would like to do some action when remote host is down. This host has a dynamic IP and DDNS service. The problem is that Netwatch in Mikrotik resolves IP only once when you add a new host. I need the script which will resolve and ping remote host every 1 minute and do some action if it`s down.

I believe that command "ping host.domain.tld" resolves ip each time. You can use it in your scripts...

Here is my script:

:local i 0; {:do {:set i ($i + 1)} while (($i < 2) && ([/ping domain.com interval=1 count=1]=0))};
        :if ($i=2) do={:log info "Main AP Down"; 
         /interface disable ether5}
