| Good Morning!
Here is today's question:
You have been asked to provide the IP adressing for the new Disaster Recovery site. You have been given 12.27.146.0 /24 from DR Facility Manager, and need to create an Internet DMZ with 20 hosts, a VPN DMZ with 10 hosts, a B2B DMZ with 11 hosts, and a production network with 112 hosts.
Please note that I will be out of the office tomorrow, so the answer will be posted with the next question on Monday 6/9. 
Here's the 6/4 question with answer:
Given the following IP address and mask, provide the class,
network ID, # subnets, and # of hosts per net:
code:
