Bring Your Own IP (BYOIP) has evolved from a niche networking feature into a core cloud strategy for cost-conscious organizations. As public IPv4 address charges from cloud providers continue to rise and multi-cloud architectures become the norm, the ability to use your own IP addresses across cloud platforms is no longer optional — it’s a competitive advantage.
This guide covers the current state of BYOIP across major cloud providers in 2026, the business case for adopting it, and how Prefixx and our sister company Netrouting can help you implement it — whether you’re deploying on public cloud, bare metal, or both.
The shift toward BYOIP accelerated after AWS introduced its $0.005 per hour public IPv4 charge in February 2024. That seemingly modest fee translates to $3.60 per IP per month, or $43.80 per year — per address. For organizations running hundreds or thousands of public IPs, the annual cost adds up fast.
BYOIP addresses are exempt from these per-hour charges on most platforms. That alone creates a compelling financial incentive. But cost savings are only part of the story.
Not all cloud platforms handle BYOIP equally. Here’s where things stand heading into 2026:
AWS was among the first hyperscalers to offer BYOIP and remains the most mature implementation. You can use your own IPv4 addresses with EC2, CloudFront, Global Accelerator, and other services. The minimum prefix size is /24, and critically, BYOIP addresses are not subject to the $0.005/hr public IPv4 fee.
AWS requires a valid Route Origin Authorization (ROA) for your prefix, which your RIR (ARIN, RIPE, or APNIC) can help you create. The onboarding process typically takes one to two weeks once documentation is in order.
Google Cloud has significantly improved its BYOIP offering. Their updated “BYOIP v2” system, enhanced in late 2025, introduced individual IP address allocation from delegated prefixes — giving you more granular control over how your address space is distributed across projects and regions.
Like AWS, GCP does not charge for idle or in-use BYOIP addresses, making it an attractive option for cost management. The minimum prefix is /24.
Azure’s approach to BYOIP is through their “Custom IP Address Prefix” feature, which allows you to bring a contiguous range that Microsoft can advertise on your behalf. While functional, the process has historically been more involved than AWS or GCP. Organizations using Azure in a multi-cloud setup should plan additional lead time for prefix onboarding.
DigitalOcean launched BYOIP support for Droplets and Kubernetes nodes, with a notably fast provisioning time of approximately 7 business days — often faster than the hyperscalers.
Oracle Cloud Infrastructure supports BYOIP for prefixes as large as /8 and as small as /24, offering flexibility for organizations with large address holdings.
Cloudflare introduced self-serve BYOIP onboarding via API, using RPKI-based validation for secure, automated prefix provisioning.
Zscaler added BYOIP capability in late 2025, enabling enterprises to use their own IP ranges for internet egress through Zscaler’s cloud security platform — a significant development for security-conscious organizations.
Public cloud BYOIP works well for many use cases, but it comes with trade-offs: minimum prefix sizes, regional limitations, provisioning delays, shared tenancy, and limited BGP control. For organizations that need more flexibility — or simply want dedicated infrastructure without the overhead of managing their own data center — there’s a better option.
Netrouting, Prefixx’s sister company, provides fully managed bare metal hosting with complete BYOIP and BYOASN (Bring Your Own Autonomous System Number) support. Unlike public cloud BYOIP, Netrouting offers:
For organizations that need the control and performance of dedicated infrastructure combined with the convenience of BYOIP, Netrouting fills a gap that public cloud providers simply don’t address. And because Prefixx and Netrouting operate under the same umbrella, you get a single point of contact from IP sourcing through deployment — no juggling separate vendors for addressing and hosting.
Purchasing IPv4 addresses outright requires significant capital — a /24 block currently costs between $9,000 and $15,000, and larger blocks scale proportionally. For many organizations, especially those scaling rapidly or testing new markets, tying up that capital isn’t optimal.
This is where IPv4 leasing paired with BYOIP becomes a powerful combination. By leasing addresses through Prefixx, you get:
Consider an organization running 512 public IPs on AWS (a /23 equivalent):
That’s nearly $20,000 in annual savings on a modest deployment. For organizations with thousands of public IPs, the numbers become transformative. And for those deploying on Netrouting bare metal, the savings stack further — no cloud IPv4 fees at all, just the lease cost and your hosting plan.
The process is straightforward, whether you’re deploying to public cloud or Netrouting bare metal:
BYOIP is quickly moving from an optimization tactic to standard practice for any organization with meaningful infrastructure spend. The combination of rising cloud IPv4 costs, maturing provider support, and improving automation (particularly RPKI-based validation) means the barriers to entry are lower than ever.
Whether you’re running a single-cloud deployment on AWS, orchestrating workloads across multiple providers, or leveraging dedicated bare metal through Netrouting, bringing your own IP addresses gives you control over costs, reputation, compliance, and portability that provider-assigned addresses simply can’t match.
Contact Prefixx to explore how BYOIP with leased or purchased IPv4 addresses — deployed on cloud, bare metal, or both — can optimize your infrastructure costs.
