Google Cloud BYOIP — Bring Your Own IP Addresses to GCP

Use your own IPv4 addresses on Google Cloud Platform via Public Advertised Prefixes. Reduce IP costs by up to 83% while leveraging Google's global network backbone.

Get Started with GCP BYOIP

What is GCP BYOIP?

Google Cloud Platform uses "Public Advertised Prefix (PAP)" for BYOIP. This allows you to bring your own public IPv4 address ranges and use them with GCP resources like Compute Engine, GKE, and Cloud NAT. GCP supports both regional and global advertisement modes, giving you flexibility in how your IP addresses are routed across Google's network.

GCP BYOIP Requirements

Before bringing your IP addresses to Google Cloud, ensure you meet these prerequisites.

Minimum /24 Prefix

Google Cloud requires a minimum prefix size of /24 (256 addresses). Larger prefixes up to /8 are supported.

ROA with AS396982

A Route Origin Authorization (ROA) must be created in your RIR account authorizing AS396982 (Google) to announce your prefix.

RIR Registration Verification

Your prefix must be registered with a recognized Regional Internet Registry (ARIN, RIPE, APNIC, LACNIC, or AFRINIC).

Google Cloud Project with Compute Engine API

An active Google Cloud project with the Compute Engine API enabled and appropriate IAM permissions for network administration.

Reverse DNS Validation

Google verifies prefix ownership via a reverse DNS (PTR) record that must resolve to a Google-specified verification token.

GCP BYOIP Setup Process

Follow these steps to bring your own IP addresses to Google Cloud Platform.

Create Public Advertised Prefix (PAP)

30 min

In the Google Cloud Console or via gcloud CLI, create a Public Advertised Prefix resource specifying your IP range and desired advertisement mode (regional or global).

Verify Prefix Ownership via ROA

2-4 hours

Create a Route Origin Authorization in your RIR portal authorizing AS396982. The ROA must propagate through RPKI validators before Google can verify it.

Verify via Reverse DNS

1-2 hours

Set up a PTR record for a specific IP in your range pointing to the verification string provided by Google. This proves operational control of the prefix.

Provision Delegated Prefix

1-2 hours

Once the PAP status changes to "validated", create a Public Delegated Prefix to sub-allocate your IP range for use with specific GCP resources.

Advertise from Desired Region

30 min

Assign IP addresses from your delegated prefix to Compute Engine instances, forwarding rules, or Cloud NAT gateways in your target regions.

Total: Approximately 24 hours

Benefits of BYOIP on Google Cloud

Why bringing your own IPs to GCP gives you a competitive edge.

No GCP IP Charges

Eliminate per-hour IP charges completely. BYOIP addresses are not subject to Google's standard external IP pricing.

Regional & Global Advertisement

Choose between regional mode (advertise from a single region) or global mode (anycast across multiple regions) based on your architecture needs.

Compute Engine/GKE/Cloud NAT Compatibility

BYOIP addresses work seamlessly with Compute Engine instances, GKE clusters, Cloud NAT gateways, and external forwarding rules.

Cross-Region Load Balancing

Use your own IPs with Google Cloud Load Balancing for globally distributed traffic management with consistent IP reputation.

Google's Global Network Backbone

Your IP addresses are routed through Google's premium-tier network, benefiting from low-latency paths and extensive peering.

GCP BYOIP FAQ

Common questions about bringing your own IP addresses to Google Cloud Platform.

What is the minimum prefix size for GCP BYOIP?

Google Cloud requires a minimum prefix size of /24 (256 addresses). You can bring larger prefixes up to /8 and subdivide them into smaller delegated prefixes within GCP.

Can I use BYOIP addresses with Google Kubernetes Engine (GKE)?

Yes. BYOIP addresses can be assigned to GKE load balancers and used as external IPs for services. They work with both Standard and Autopilot GKE clusters.

What is the difference between regional and global PAP mode?

Regional mode advertises your prefix from a single GCP region, ideal for geo-targeted services. Global mode enables anycast advertisement across multiple regions, suitable for globally distributed applications.

How long does GCP BYOIP verification take?

The full process typically takes about 24 hours. ROA propagation (2-4 hours) is usually the longest step. Google's automated verification runs continuously once records are in place.

Are there any ongoing charges for BYOIP on GCP?

Google does not charge per-IP fees for BYOIP addresses. However, standard data transfer and load balancing charges still apply. Your only IP cost is the lease from IPv4Center.

Can I move my BYOIP addresses between GCP regions?

With global mode PAP, your addresses can be used across regions. With regional mode, you would need to re-provision the delegated prefix in a new region, which takes minimal time.
