[olug] Subnet mask

[Craig Wolf]

I am having a brain freeze and I cannot for the life of me figure this out.  I have been given a range of numbers to use at my job and I cannot figure out the subnet mask...Help!
The numbers are 205.202.101.64-205.202.101.93.  Class C address from authority.  I know that by thinking about it, it is divided into 4 subnets, right? (30 numbers into 128 is 4 times+).  ugh.  My head hurts today...
