This maybe a dumb question but I want to block all IPs in my firewall starting with 149.129.xx.xx
. I'm not able to figure out what to enter in my firewall setting. The field asks me for IP/Netmask and by default sets it to /32
.
So If I enter 149.129.0.0
, it makes it 149.129.0.0/32
. I know how to mask the last part of the IP using 149.129.47.0/24
but I can't understand how it works. What would be the equivalent mask if I want to cover last 2 parts of the IP?
