Customers using the [Subscriber Provided Prefix (SPP)](https://docs.fastly.com/products/subscriber-provided-prefix)
product are provided with additional APIs to create and update DNS and TLS configurations for IP addresses hosting
services on Fastly. These API enhancements enable a SPP customer to configure various attributes (including supported
TLS versions, HTTP versions, or IPv4 and IPv6 dual-stack host names) on their service endpoints.

- [DNS Configuration](https://www.fastly.com/documentation/reference/api/ip-configuration/spp/dns-configuration/) - Customers with access to multiple sets of IP pools are able to manage DNS records associated with the IP pools.
- [TLS Configuration](https://www.fastly.com/documentation/reference/api/ip-configuration/spp/tls-configuration/) - Customers with access to multiple sets of IP pools can apply different configuration options to their TLS-enabled domains.
