With an IP address set starting with 150, you currently have six offices that you are treating as subnets. Plans are in place to open 10 more offices before the end of the year. What subnet mask should you use to satisfy the needed number of subnets and maximize the number of hosts available at each site?
Using the illustration from the previous question, what would be the IP address of S0 if you were using the first subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP address in the range. Again, the zero subnet should not be considered valid for this question.
