To get a wildcard mask from a subnet mask you invert the mask. In your
first example, the mask is 255.255.255.0 and you inverted it to become
0.0.0.255.
In your second example you have a mask of 255.255.255.224. What do you
get when you invert that mask?

Folks,
For network 10.1.0.0/24 ..the access list would be
access_list 120 permit ip 10.1.0.0 0.0.0.255 any
What would be access list if my network is 10.1.0.0/27?
Cheers

/27 is ...111 which the same as 255.255.255.224
So you have 10.1.0.0 subnet mask 255.255.255.224
255.255.255.255
- Subnet mask 255.255.255.224
