IP address service bindings

Within IP address management, service binding refers to the association of an IP (or a range of IPs) to specific Cloudflare services.

Note

Service binding operations are currently only available via API. You can find all endpoints and their specifications in the Cloudflare API documentation.

Scope

Currently, if you have BYOIP configured with Magic Transit, you can use the service binding API endpoints to add CDN or Spectrum capabilities on top of Magic Transit.

CDN (Cache)

When you add the CDN service binding, any HTTP requests received via designated IPs are directed into the CDN pipeline (for Layer 7 processing) as they reach the Cloudflare network.

Spectrum

Adding Spectrum allows you to benefit from Cloudflare security and performance for Layer 4 traffic.

Limitations

• It is currently not possible to use both Spectrum and CDN together with the Magic Transit service. You must choose one or the other when upgrading your IPs.
• You must keep Magic Transit as a common base service, spanning all addresses in your prefix.
• Once a service binding is created, its propagation across the Cloudflare network will take four to six hours to complete.
