Summarizing ACLs

I would like to block networks 10.0.0.0/24 through 10.0.239.0/24 from accessing networks 10.0.240/20

I've come to the conclusion that the best way of doing this is with 4 separate acl's:

ACL 1 - 0.0 - 127.255

ACL 2 - 128.0 - 191.255

ACL 3 - 192.0 - 223.255

ACL 4 - 224.0 - 239.255

I'm wondering of this is correct, or if there is a way to encompass 10.0.0.0 - 10.0.239.255 into once ACL statement.

As always, thank you in advance.

There is no way to

There is no way to accommodate networks 10.0.0.0/ 24 through 10.0.239.0/24 in one ACL statement.  The most efficient solution is the one that you have already presented.
