Question

I have a client and they are currently working on firewalls deployment on Azure and running out of static Public IP addresses. I would like to know what options exist for us to add more static public IP addresses on Azure.

Options to add more static public IP addresses on Azure

Create more Public IP resources: You can create a new Public IP address resource and associate it with the required resource, such as a virtual machine, load balancer, or firewall. While creating the Public IP address resource, make sure to choose the "Static" allocation method. You can follow the steps in this documentation to create a Public IP address: https://docs.microsoft.com/en-us/azure/virtual-network/create-public-ip

• Increase Public IP address limit: Azure subscriptions come with default limits on the number of Public IP addresses that can be created per region. If your client has reached the limit, you can request an increase in the limit through the Azure portal. To do this, open a support request by navigating to the "Help + support" section in the Azure portal, and then click "New support request." Choose "Service and subscription limits (quotas)" as the issue type and follow the instructions to request an increase in the Public IP address limit.
• Use a Load Balancer or Application Gateway: If your client needs to distribute incoming traffic across multiple VMs or services, you can use a Load Balancer or Application Gateway with a single static Public IP address. Both services support multiple backend pools, allowing you to distribute traffic to different resources without needing multiple Public IP addresses.
• Use a NAT Gateway: If your client needs to provide outbound connectivity for multiple VMs with a single static Public IP address, consider using a NAT Gateway. A NAT Gateway enables you to use a single static Public IP address to provide outbound connectivity for multiple VMs without exposing them directly to the internet.

Hello @Love Arinze Thank you for reaching out. If I understand correctly, you are running out of static Public IP addresses for your subscription and you want to know if there is a way to increase the quota for your subscription. If my understanding is correct, you can follow the documentation mentioned here to increase a static public IP address quota for your subscription. To increase a static public IP address quota, select Other in the Resources list, then specify the information in the Details section as mentioned in the document linked above. Hope this helps! Please let me know if you have any questions. Thank you!
