How To Assign a Secondary Private IP in AWS and Configure NGINX: A Step-by-Step Guide

Hey, did you know you can assign multiple IPs to the same server and even have different services on your server use those separate IPs? Sounds cool, right? In this article, I’ll show you how to assign a secondary private IP to your AWS EC2 instance and configure NGINX to handle it, step by step!

What is a Secondary Private IP Address?

A secondary private IP is an additional IP address that can be assigned to a network interface on your EC2 instance, alongside the primary IP. It offers flexibility, failover capabilities, and allows multiple services to run on the same instance using different IPs.

Key benefits:

• Host Multiple Services: Use distinct IPs for different websites or services on a single server.
• Resource Efficiency: Rather than spinning up new servers, simply add an extra IP.
• Failover: In case of failure, the secondary IP can be reassigned to a standby instance seamlessly.
• IP Management: If you’ve exhausted available IPs in a subnet, secondary IPs help maximize the usage of your current server setup.
