CIDR allows flexible IP address assignment using variable-length subnet masking (VLSM), supporting both public and private IP ranges in the cloud. What is CIDR? CIDR (Classless Inter-Domain Routing) is a method for allocating IP addresses and routing Internet Protocol packets using a compact representation like 10.0.0.0/16. CIDR Notation Breakdown Format: IP_address/prefix_length Example: 192.168.1.0/24 IP Address: 192.168.1.0 Prefix Length: /24 means 255.255.255.0 (first 24 bits are network bits) CIDR and Subnet Masking /16 = 65,536 IP addresses /24 = 256 IP addresses /28 = 16 IP addresses AWS uses CIDR blocks when creating: VPCs Subnets Route Tables Security Configurations CIDR in AWS Networking 1. VPC CIDR Block When creating a VPC in AWS, you define a primary IPv4 CIDR block (e.g., 10.0.0.0/16) Optional: Add secondary CIDR blocks for more subnets using VPC IP address expansion. 2. Subnet CIDR Block Subnets must use a portion of the parent VPC CIDR. Example: VPC: 10.0.0.0/16 Subnet 1: 10.0.1.0/24 Subnet 2: 10.0.2.0/24 Private vs. Public IPs in AWS Private IP Addresses Definition: IPs not routable over the internet; used for internal communication. Common Ranges (RFC 1918): 10.0.0.0 – 10.255.255.255 (10/8) 172.16.0.0 – 172.31.255.255 (172.16/12) 192.168.0.0 – 192.168.255.255 (192.168/16) Used In: EC2 internal networking Databases Private Subnets Public IP Addresses Definition: Routable over the public internet. Assigned to: EC2 instances in public subnets Load balancers NAT Gateways (for outbound access) Allocated From: AWS's pool of IP addresses Or by Elastic IPs (static public IPs) Practical Use Cases Scenario 1: Public Web Server VPC CIDR: 10.0.0.0/16 Subnet CIDR: 10.0.1.0/24 (Public Subnet) Assigned: Private IP: 10.0.1.10 Public IP: 13.234.56.78 Purpose: Accessible from the internet. Scenario 2: Private Database Server Subnet CIDR: 10.0.2.0/24 (Private Subnet) Assigned: Private IP: 10.0.2.20 No Public IP Purpose: Internal access only (e.g., from Bastion Host or App Layer). Best Practices 1. Plan CIDR blocks carefully to avoid overlaps in hybrid or multi-VPC setups. 2. Use subnet sizes that match your scaling needs. Don't over-allocate. 3. Split subnets across AZs for high availability. 4. Avoid using small subnet masks like /28 for production services unless truly needed. Conclusion Understanding CIDR and the use of public and private IPs is foundational for any AWS architect or cloud engineer.
