CIDR Block Guidelines

Common CIDR blocks for VPCs:

CIDR	IP Range	Hosts
/16	10.0.0.0 - 10.0.255.255	65,536
/20	10.0.0.0 - 10.0.15.255	4,096
/24	10.0.0.0 - 10.0.0.255	256

Best Practices

Use private IP ranges (10.x, 172.16-31.x, 192.168.x)
Plan for future growth
Avoid overlapping with existing networks
