Question

Network administration

I can't figure out how to do it. 40.77.167.xxx is what you need for this mask. I don’t understand English very well. I
wrote

out the entire list of values ​​​​that are for blocking:

As Num
cookie
country
hostname
IP address
Referer
Request method
SSL\https
URL Full
URL
URL Path
URL query string
HTTP version
user agent
x-forwarded-for
Known boards
threat score

Answer 1

and what can be chosen instead of the field "Field - Ip address"? isn't there a "net" value?
because it is necessary to block 40.77.167.0 netmask 24 (255.255.255.0)
And yet - what are you trying to block when specifying the broadcast address x.x.x.255?

Answer 2

there you can have a grid in /32 notation, etc.

Answer 3

IP address is in 40.77.167.0-254 ?
