Nothing that I can figure out. I'll lay you odds you can't even get the IOS CLI to accept this command ( routers off line again, so I can't check right now ) if the line were to read access-list 52 permit 10.11.217.0 0.0.0.63 then I might be of more help. If the line were to read ( under an OSPF process ) Network 10.11.217.0 0.0.0.63 area 12 I might be of more help. In the first case, you have a standard access-list permitting all hosts with their first three octets exactly matching 10.11.217 and also matching 0 through 63 in the fourth octet. Write it out in binary and you will see why this is true. In the second case, you would be placing all interfaces with addresses from 10.11.217.0 through 63 into the ospf process as participating in area 12.
