Release or Retain a Public IP

This guide explains how Public IP addresses behave when a resource is removed, and how to release or retain a Public IP in CloudRaya.

Understanding this behavior helps you:

• Avoid unnecessary charges
• Preserve IP addresses for reuse
• Manage Public IP quota efficiently

What Happens to a Public IP?

A Public IP in CloudRaya is a separate network resource.

This means:

• Public IPs are not automatically deleted when a VM or resource is removed
• Public IP lifecycle is independent from the resource lifecycle

When a resource is deleted, the Public IP may be retained or released, depending on your action.

Retain vs Release: What’s the Difference?

Retain a Public IP

When you retain a Public IP:

• The IP is detached from the resource
• The IP remains in your Public IP list
• The IP can be:
  • Reattached to another VM or Load Balancer
  • Reused to preserve DNS mappings
• The IP continues to count toward your quota
• The IP continues to be billed

This is useful when you want to keep a stable IP address.

Release a Public IP

When you release a Public IP:

• The IP is permanently removed
• The IP is returned to the CloudRaya pool
• Billing for that IP stops immediately
• The IP cannot be recovered

Use this option when the IP is no longer needed.

Retaining a Public IP When Deleting a Virtual Machine

When deleting a VM that has a Public IP attached:

1. Open VM Detail
2. Click Delete VM
3. Review the confirmation dialog
4. Choose whether to:
   • Retain Public IP, or
   • Release Public IP
5. Confirm the deletion

If You Retain the IP

• The VM is deleted

• The Public IP remains available

• The IP appears in:

  Dashboard → Network → Public IP Address

• The instance field will be empty

You can reuse this IP later.

📄 See: Use an Existing Public IP

If You Release the IP

• The VM is deleted
• The Public IP is deleted permanently
• The IP is removed from the Public IP list
• Billing stops for that IP

Releasing an Unused Public IP Manually

You can also release a Public IP that is not attached to any resource.

Steps:

1. Open Dashboard → Network → Public IP Address
2. Locate an unused Public IP
3. Click Delete
4. Confirm the action

This immediately frees quota and stops billing.

Billing and Quota Implications

Important behavior to note:

• Retained Public IPs:
  • Continue to consume quota
  • Continue to incur charges
• Released Public IPs:
  • Free up quota immediately
  • Stop billing immediately

If you reach the Public IP limit:

• You must release unused IPs before acquiring new ones

Common Use Cases

When to Retain a Public IP

• Preserving DNS records
• Migrating workloads
• Replacing a VM without changing IP
• Temporarily removing a resource

When to Release a Public IP

• Resource is permanently removed
• No future reuse is planned
• You want to reduce cost
• You need to free quota

Important Notes

• A retained Public IP is not attached to any resource
• Retained IPs remain visible in the Public IP list
• Public IPs cannot be moved across Cloud Zones
• Once released, a Public IP cannot be restored

Summary

• Public IPs are independent resources
• Deleting a VM does not automatically delete its Public IP
• You must choose to:
  • Retain the IP for reuse, or
  • Release the IP to stop billing
• Proper IP management prevents quota and billing issues
