Hi

I have a script setup which looks into dns cache and adds any address which relates to Netflix and puts it into the address list, I then have a routing mark which send the traffic down another route based on the address list and it works, however I do have an issue and need some help.

The script is:

/log info ("Starting Netflix script");
:foreach i in=[/ip dns cache all find where (name~"netflix")] do={
:local tmpAddress [/ip dns cache get $i name];

:if ( [/ip firewall address-list find where address=$tmpAddress] = "") do={
:local cacheName [/ip dns cache get $i name] ;
/log info ("added entry: $cacheName $tmpAddress");
/ip firewall address-list add address=$tmpAddress list=netflix-hosts;
}
}
/log info ("Ending Netflix script");


My issue is, the address list it creates are “dynamic” and it request DNS lookups every 3 seconds causing lots of DNS requests on my router, is there a command I can put into the script which changes the frequency/timeout?

I have this script duplicated for other websites which I need to send down other routes so my “dynamic” list is growing rapidly.

I’m using RouterOS 7.11.2

Thanks

ROS is resolving host in address list on interval set by TTL (Time To Live) in DNS record, if is short it will perform DNS requests often, if you have added many hosts even more often, each host is resolved in separated DNS request and each can have different TTL. You can't manually set resolving rate.
