VIP Platform IP ranges

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.

Publicly accessible IP ranges for VIP’s origin data centers can be found at this endpoint: https://go-vip.net/ip-ranges.json

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:

  • The serial JSON field within the response contains an epoch timestamp of the last change.
  • The updatedAt JSON field within the response contains an ISO 8601 timestamp of the last change.
  • HTTP response of requests made with the If-Modified-Since header. If the last modification date/time is newer than the value provided in the If-Modified-Since request header, the response will be HTTP 200 OK. Otherwise, the response will be HTTP 304 Not Modified.
