Hello Guys,
I’m looking for the right way about how to block a hostname using a script, I found 2 different ways to do that but It’s not working that way, unfortunately 
..
check this post .. http://forum.mikrotik.com/viewtopic.php?f=2&t=18815&p=117397&hilit=block+hostname#p117397
PS: I tried the 2 ways on ROS 2.9.27 and 3.11.
Please Advice ..
