Waste signals
- Reserved IPs unattached > 14 days
- Reserved IPs from decommissioned services
- Surplus IPs on multi-AZ load balancers
GCP External IPs cost optimization
Static external IPs charge while reserved if unattached. TurboFinOps inventories every reserved IP, attachment state and last-attached timestamp.
Typical savings range$50-$1,200 / monthGCP project with > 50 reserved IPs
Optimization levers
- Release unattached static IPs after cooldown
- Consolidate load-balancer IPs where SAN cert allows
Workflow
How TurboFinOps closes the loop
1. Scan
Inventory reserved IPs and attachment state.
2. Surface
Findings flag idle addresses.
3. Approve
Release passes conflict guard + DNS dependency check.
4. Verify
Receipts confirm the IP line drops.
FAQ
Frequently asked questions
What if a released IP is later needed at the same address?+
GCP does not guarantee re-allocation of the same address. The approval card surfaces this risk; DNS-pinned IPs are flagged as high risk.
Is this also for IPv6?+
Yes — IPv6 reservations follow the same pattern.
