Your ISP assigns your company a 206.206.155.0/24 CIDR block. Your company has four different networks:

Network A: 50 users
Network B: 26 users
Network C: 12 users
Network D: 10 users
Your job is to create four subnets and allocate enough IP addresses for the users within the network. Document how you will do this.

You can change the CIDR to any private IP range, such as 172.16.1.0/24. Using
the public IP in this situation is more realistic because the ISP only assigns a
public IP CIDR.
Several answers will satisfy the design criteria. Here are two possible answers:
• This will leave room to create more subnets if you need to add more
networks:
Network A: 206.206.155.0 255.255.255.192
Network B: 206.206.155.64 255.255.255.224
Network C: 206.206.155.96 255.255.255.240
Network D: 206.206.155.112 255.255.255.240
• This will leave room for adding more users:
Network A: 206.206.155.0 255.255.255.192
Network B: 206.206.155.64 255.255.255.192
Network C: 206.206.155.128 255.255.255.192
Network D: 206.206.155.192 255.255.255.192
