It looks like the first ACL matches 224.0.0.0 to 231.255.255.255 and the
second one matches from 232.0.0.0 to 238.255.255.255.
I think, what you are asking is why not
deny 239.0.0.0 0.0.0.255
permit 232.0.0.0 7.255.255.255
If I understand you correctly, the group-list ACL cannot have deny
statement. It supports only permit statement.

hi
In this task 2 acl are required
one matching 224.0.0.0/5 the other matching 232.0.0.0/5
the solution shows this for 224.0.0.0/5:
ip access-list standard GROUP_224
permit 224.0.0.0 7.255.255.255
and for 232.0.0.0/5
ip access-list standard GROUP_232
permit 232.0.0.0 3.255.255.255
permit 236.0.0.0 1.255.255.255
permit 238.0.0.0 0.255.255.255
can someone explain this to me?
Thanks
Abderrahim
