A Beginner-Friendly Guide to AWS Networking with IP Addressing
When learning cloud computing, one of the core areas to master is networking, and in AWS, it all begins with IP addressing.
Whether you’re an aspiring cloud engineer or prepping for AWS certification, understanding how IP addresses work inside AWS VPC (Virtual Private Cloud) is key to designing secure and scalable cloud architectures.
If you're looking to master cloud skills, Eduleem offers the best AWS training in Bangalore with real-world networking projects, expert-led classes, and placement support.
What is IP Addressing in AWS?
IP addressing is a critical component in AWS networking. Every device in a network requires an IP address to communicate—just like a house needs an address to receive mail.
- In AWS, IP addresses are used to:
- Identify resources within a VPC
- Enable communication between services
- Control access through security groups and NACLs
Key Concepts of IP Addressing in AWS
1. Private and Public IP Addresses
- Private IPs are used for communication within your VPC.
- Public IPs (IPv4) allow instances to be accessed over the internet.
💡 Example: If you launch an EC2 instance in a public subnet, it can be assigned both private and public IPs.
2. Elastic IP Addresses (EIP)
- Static public IPv4 address you can allocate and associate with resources.
- Perfect when your instance needs a consistent IP address, even after reboot.
3. CIDR Blocks and Subnetting
When you create a VPC, you assign a CIDR block (e.g., 10.0.0.0/16) which defines the IP address range. You can then split this into subnets.
- /16 = 65,536 IP addresses
- /24 = 256 IP addresses
📌 Best practice: Use smaller subnets for better security and resource segmentation.
4. IPv6 in AWS
- AWS also supports IPv6, which is a newer protocol with a much larger address space.
- Enables internet access without NAT.
🌍 Many organizations are adopting IPv6 for global-scale applications.
5. Security Groups and IP Rules
- AWS security groups let you allow/deny traffic based on IP address ranges.
- Example: Allow only your corporate IP to SSH into an EC2 instance.
6. VPC Peering and IP Routing
With VPC Peering, you can connect two VPCs privately using IP route tables.
- No need for internet gateways or NAT.
- Enables cross-VPC resource sharing.

Real-World Use Case: IP Addressing in Multi-Tier Architecture
Imagine you’re building a three-tier architecture:
- Web Tier → Public Subnet → Public IPs
- App Tier → Private Subnet → Only Private IPs
- DB Tier → Private Subnet → Strictly internal IP access
Using correct IP ranges ensures security, routing efficiency, and scalability.
