In some situations, it might be necessary to allow requests from a VIP Platform environment that may need to interact with private resources. For example, to allow requests from a VIP Platform site to an internal tool that is behind a firewall.
Adding the provided IP range for a given data center will allow a site to communicate with a restricted platform/resource.
Precautions around IP range updates
VIP Platform IP ranges are subject to change at any time, and advance warning of IP range updates is not provided.
For this reason, applications should be built in such a way that unexpected IP range updates are non-breaking, either because the ranges are not required for vital site functionality, a fallback method is provided, or some other strategy.
There are a few mechanisms to monitor updates to the published ranges:
serialJSON field within the response contains an epoch timestamp of the last change.
updatedAtJSON field within the response contains an ISO 8601 timestamp of the last change.
- HTTP response of requests made with the
If-Modified-Sinceheader. If the last modification date/time is newer than the value provided in the
If-Modified-Sincerequest header, the response will be
HTTP 200 OK. Otherwise, the response will be
HTTP 304 Not Modified.
