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.
Scope
Currently, if you have BYOIP configured with Magic Transit, you can use the service binding endpoints to add CDN or Spectrum capabilities on top of Magic Transit.
CDN (Cache)
Adding the CDN service binding ensures that any HTTP requests received via designated IPs are directed into the CDN pipeline for Layer 7 processing as they land on the Cloudflare network.
Refer to Use BYOIP with Magic Transit and CDN to learn how to set this up.
Spectrum
Adding Spectrum allows you benefit from Cloudflare security and performance for Layer 4 traffic.
API
Service binding operations are currently only available via API. You can find all endpoints and their specifications in the Cloudflare API documentation.
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.
