I recenty took the CCNA exam and came across the following issue
You are given an ip range of 172.16.1.50 – 172.16.1.59 from an ISP. Can you determine the prefix by adding up the number of IP addresses, and finding what VLSM block size they fit into (172.16.1.50/28) for purposes of creating an IP Nat pool (172.16.1.50 255.255.240) or must you use the classful mask (255.255.255.0)
Or can this question be answered given the information supplied??
I've tried to find an answer everywhere
Thanks in advance
