Dedicated IP addresses

Dedicated IP addresses provide a pool of IPv4 and IPv6 IP addresses, maintained and managed by Fastly, across our global edge cloud platform. This can be used for supporting non-SNI traffic, platform customer support, zero rating billing identification, or securing access through IP control lists.

  • Support for non-SNI traffic

    Dedicated IP addresses can be used to support non-SNI traffic. Fastly can install customer-provided certificates at a dedicated set of IP addresses identified via customer-managed DNS records.

  • Simplified management of large domain lists

    With dedicated IP addresses, IP-to-Service Pinning is used to help customers who are managing a large number of domains that need to be mapped to a single service. This option simplifies the management of large domain lists.

  • More personalized control

    Fastly supports a number of standard cipher suites. Should you require more personalized control, Fastly allows you to create custom cipher suites by providing you with dedicated IP addresses that support these custom sets.

  • Zero-rated billing identification

    Zero-rated IP addresses (ZRIPs) allow you to use dedicated IP addresses within Fastly’s global Edge Cloud to identify traffic for special treatment. For example, if you need to waive billing charges going to or from specific web resources, ZRIPs provides that support.

  • Security allowlisting

    Use a dedicated set of Fastly global IPs to inform your egress access control lists (ACLs) on security sensitive applications outside of Fastly.

Subscriber Provided Prefix

  • Bring Your Own IP (BYOIP)

    For customers who want to control their address space by separating their network layer concerns from their content delivery concerns, Fastly's Subscriber Provided Prefix, allows you to have your IP address ranges announced, routed and served by Fastly infrastructure for use with production services. Provide your own IP address space to Fastly, then direct traffic to your own IP addresses.

Frequently Asked Questions

What is a dedicated IP address in Fastly?

A dedicated IP address is an IP assigned exclusively to a single Fastly customer instead of being shared with other customers. It provides isolation, predictable behavior, and greater control at the network edge.

What are the benefits of a dedicated IP address?

The benefits of a dedicated IP address include stronger security isolation, consistent traffic reputation, simplified IP allowlisting, and predictable TLS and firewall behavior. It’s commonly used for enterprise and compliance-driven environments. Because Fastly dedicated IP addresses are anycast, end users are automatically routed to the closest Fastly POP worldwide, ensuring optimal performance and low latency regardless of location.

When should a company use a dedicated IP address?

Companies use a dedicated IP address when they need static IP identification, IP-based access controls, legacy system integration, or tighter security and compliance controls at the edge.

How does Fastly’s dedicated IP address hosting differ from shared IPs?

Dedicated IP address hosting assigns IPs exclusively to your Fastly services, while shared IPs are used by multiple customers. Dedicated IPs offer greater control, observability, and policy enforcement without shared-tenant risk.

Do dedicated IP addresses affect performance?

No. Dedicated IP addresses do not impact performance. Fastly's global edge network still delivers traffic with the same low-latency routing and caching capabilities.

Are dedicated IP addresses required for TLS or HTTPS?

Dedicated IP addresses are not required for TLS, but they are often used to support legacy TLS configurations, static IP allowlists, or strict security and certificate management requirements.

How do dedicated IP addresses support security and compliance?

Dedicated IP addresses support security and compliance by enabling IP-based firewall rules, deterministic routing, and reduced shared-infrastructure risk.

Can dedicated IP addresses be used with other Fastly products?

Yes. Dedicated IP addresses work with Fastly CDN, TLS, WAF, DDoS protection, and edge compute, allowing consistent security and traffic policies across services.

How do you get a dedicated IP address on Fastly?

Dedicated IP addresses can be provisioned directly through Fastly as part of your service configuration and managed globally at scale.
