How to Reserve IP Addresses in Google Cloud Platform (GCP)
Mitaarrr’s of the Tech Universe!
Welcome to my blog! Today, we'll dive into a crucial topic in network management: Reserving IP addresses in Google Cloud Platform (GCP) . There are times when organizations face subnet exhaustion and run out of IP addresses. At this point, reserving IPs becomes essential, ensuring that you have them available for future use.
Why Reserve IP Addresses?
Running out of IP addresses can be a significant challenge for any organization. This situation might arise when subnets get exhausted due to rapid scaling, unexpected project expansions, or other unforeseen factors. Reserving IP addresses ensures you have a pool of addresses ready to deploy as needed, preventing downtime and maintaining seamless operations.
Reserving an IP address is akin to setting aside a parking spot for your most important guests. It ensures that a specific IP address is held for future use, preventing the hassle of re-configuring devices or services when a subnet reaches its limit. This practice is particularly beneficial for organizations that anticipate growth or have critical services that require a permanent IP address.
Steps to Reserve IP Addresses in Google Cloud
Open Google Cloud Console:
Log in to your Google Cloud account.
In the search bar, type "IP address" and click on the IP Addresses tab.
Choose the Type of IP Address:
Depending on your needs, you can reserve either an external static IP address or an internal static IP address.
Many organizations opt for internal static IP addresses for internal network management.
For a detailed explanation of the differences and use cases, check out my previous post on Internal vs. External Static IP Addresses.
Reserve an Internal Static IP Address:
Click on Internal Static IP Address.
Fill in the required details:
Name: Enter a name for the IP address using your preferred naming convention.
IP Version: Choose between IPv4 and IPv6.
Networks: Select the network within the project or shared with you.
Static IP Address: You have two options: assign automatically or choose manually. If you opt to choose manually, select the desired IP address.
Purpose: Specify whether it's for shared or non-shared use.
Click on Reserve.

Challenges and Best Practices
Reserving IP addresses might seem straightforward, but it comes with its own set of challenges. Here are a few tips to make the process smoother:
Proper Planning: Ensure you have a well-thought-out IP addressing scheme to avoid conflicts and manage resources efficiently.
Documentation: Keep detailed records of reserved IP addresses to avoid confusion and ensure easy management.
Regular Audits: Periodically review your IP address reservations to optimize usage and release any unused addresses.
By following these steps, you can ensure that your network infrastructure remains robust and scalable. Reserving IP addresses is a proactive measure to prevent disruptions and maintain efficient network management.
