Converting an ACL Filter with Wildcard Mask to a Range of IP Addresses

Which IPv4 address range covers all IP addresses that match the ACL filter specified by with wildcard mask

The ACL filter specified as with a wildcard mask of can be converted to a range of IP addresses using the following steps:

1. Convert the wildcard mask to its binary form: becomes 00000000.00000000.00000001.11111111.

2. Determine the network address by performing a bitwise AND operation between the ACL filter and the inverse of the wildcard mask. In this case, the inverse of 00000000.00000000.00000001.11111111 is 11111111.11111111.11111110.00000000, so the network address is

3. Determine the broadcast address by performing a bitwise OR operation between the network address and the wildcard mask. In this case, the broadcast address is obtained by ORing with 00000000.00000000.00000001.11111111, resulting in

Therefore, the range of IP addresses covered by the ACL filter with wildcard mask is from to
