/ip firewall address-list add address=[/ip dns cache get $k address] list=list_ticketing disabled=no comment="res.sriwijaya-air-online.com"
}
}
}

what that script doesn't work.. but if i change it with google.com, klikbca.com then it works.. why?

Maybe "res.sriwijaya-air-online.com" is not showing up in "/ip dns cache". Try "/ip dns cache all" it will show all entries including CNAME and NS
