Google Cloud Expands BYOIP to All Regions: What This Means for IPv4 Holders

March 5, 2025

2 min read

Google Cloud’s expansion of BYOIP to all regions in 2025 is a big deal for anyone juggling cloud IP costs. Bring-your-own-IP was already available in some regions; now it is global. If you hold IPv4 or are considering leasing, the GCP BYOIP update changes the math.

What BYOIP Does

BYOIP (bring your own IP) lets you use your own IPv4 addresses in Google Cloud instead of addresses assigned by Google. You own or lease a block, announce it via BGP, and point it at your GCP resources. In return, you can avoid or reduce the public IP surcharges that cloud providers now charge.

AWS and Azure have had similar programs for a while. Google’s 2025 expansion means GCP is now on par: BYOIP is available in every region where it makes sense. That gives users more flexibility and another way to manage IPv4 cost in the cloud.

Why It Matters for IPv4 Holders

If you own or lease IPv4, the GCP BYOIP update creates more options. You can use your block in GCP workloads instead of paying per-address surcharges. For cost-sensitive applications—hosting, proxies, APIs—that can add up quickly.

Holders who lease out IPv4 can also serve this market. Lessees who run on GCP may want to bring their leased block into the cloud. Our how to lease out IPv4 guide walks through listing your space, structuring agreements, and managing the relationship.

What You Need to Use BYOIP

BYOIP is not plug-and-play. You need an IPv4 block (typically /24 or larger), control over BGP announcement, and compliance with Google’s requirements. The block must be properly registered and have a clean reputation.

If you do not already have a block, you can buy or lease from the secondary market. Lease fits when you need medium-term capacity without a large upfront payment. The GCP BYOIP update makes that path more attractive for users who want to control cloud IP costs.

Bottom Line

The Google Cloud BYOIP expansion in 2025 levels the playing field with AWS and Azure. IPv4 holders and lessees have one more way to use their space and reduce cloud surcharges. If you hold or lease IPv4 and run on GCP, it is worth revisiting the BYOIP option.

Frequently asked questions

What is Google Cloud BYOIP?

BYOIP (bring your own IP) lets you use your own IPv4 addresses in GCP instead of Google-assigned ones. You announce your block via BGP and use it for GCP resources. It can reduce or avoid public IP surcharges.

What changed with GCP BYOIP in 2025?

Google Cloud expanded BYOIP to all regions in 2025. Previously, support was limited. The GCP BYOIP update means more users can bring their own IPv4 and control cloud IP costs.

Should I lease IPv4 for BYOIP?

Leasing can work if you need medium-term capacity for BYOIP without a large upfront buy. Check GCP BYOIP requirements for block size and announcement rules; our how to lease out IPv4 guide covers the holder side.

How does BYOIP affect cloud IPv4 costs?

Using your own IP with BYOIP can reduce or eliminate public IP surcharges. That makes leased or owned IPv4 more attractive for cost-sensitive workloads.

What do I need to use BYOIP in Google Cloud?

You need an IPv4 block (typically /24 or larger), control of BGP announcement, and compliance with GCP requirements. Leasing or buying from the secondary market can provide the block.
