This is one of the best explanations I've seen. I'm studying CCNA at school and ACLs seem OK at first until I frustrated and can't recall how to get the IP range from an ACL. The majority of explanations are "just subtract 255" but there is so much more to it. Well done Mr. System Engineer you earned an upvote from me!
simplest way of explaining them, just got another question ,what if we got 0.0.0.01000000 as wild card mask ,are we gonna match the only one bit normally???
Help! This is a cisco excersice. This is the ACL statement below. Deny all hosts from the 10.10.10.0/24 network. What is the wildcard mask? The "correct" answer is 0.0.0.255. But another question is: This is the ACL statement below. Permit all hosts from the 192.168.5.0/27 network. What is the wildcard mask? The answer is 0.0.0.31. If we use the technique in the video is makes sense. 255.255.255.255 - 255.255.255.0 = 0.0.0.255 255.255.255.255 - 255.255.255.224 = 0.0.0.31 Should the wildcard mask be different depending on if we want deny or permit?

So easy to understand in such a short time, thank you!

Easy Explanation to understand wildcard masks. Thank you
Thank you professor.
you are simply the Best thank you
Great job, thanks!

This is way easier to understand when you understand how to calculate subnet masks.
big brain vid i lern a lot pls ty
The more videos I watch the more I get it
Help! This is a cisco excersice.
This is the ACL statement below.
Deny all hosts from the 10.10.10.0/24 network.
What is the wildcard mask?
The "correct" answer is 0.0.0.255.
But another question is:
This is the ACL statement below.
Permit all hosts from the 192.168.5.0/27 network.
What is the wildcard mask?
The answer is 0.0.0.31.
If we use the technique in the video is makes sense.
255.255.255.255 - 255.255.255.0 = 0.0.0.255
255.255.255.255 - 255.255.255.224 = 0.0.0.31
Should the wildcard mask be different depending on if we want deny or permit?
Thank you!
Thanks so much.
THANK YOU!!!!!!!!!!
Great job...

Great!
Neither subnet masks nor wildcard masks can have a value of 17 in an octet?
Bruno B why?
Yes, they can.
