Real-World Examples
Understanding practical network infrastructure planning scenarios helps architects make informed design decisions:
Corporate Headquarters
A 500-employee corporate headquarters requires a /22 subnet (255.255.252.0) for the main office network, with /26 subnets for different departments and /30 subnets for point-to-point links.
Example: 10.0.0.0/22 provides 1022 usable addresses for the main network
Data Center Network
A data center with 1000 servers uses /24 subnets for server farms, /28 subnets for management networks, and /30 subnets for inter-switch links.
Example: 172.16.0.0/24 provides 254 addresses for server farm A
Branch Office Network
A branch office with 50 users requires a /26 subnet for the main network, with separate /28 subnets for guest access and IoT devices.
Example: 192.168.1.0/26 provides 62 addresses for the main office network
Tips for Network Infrastructure Planning
Document Everything

Important Network Disclaimers
This calculator provides planning assistance for network infrastructure design. Always consult with qualified network architects and engineers for production implementations.
Network infrastructure planning should consider organizational policies, regulatory requirements, and industry best practices. Test all designs in non-production environments before deployment.
Ensure compliance with security standards and access control requirements when implementing network designs. Consider factors such as user authentication, authorization, and audit logging.
