The nature of cloud services is that IP addresses may change. Exostar as been assigned dedicated IP ranges from which services may originate. To prevent any issues with IP addresses changing in the future your company should whitelist the entire range. The last octet (bit) of your IP address may not be the same as the current IP address's octet (bit) in the future.

If the API call is using one of the IPs in the Current segments, then this would impact the API calls. The API call user may have to restart the API service. If the API call uses DNS, then there should not be an issue.

It is not mandatory for every business user to clear the DNS cache. However, if the client DNS is handled properly once the Time-To-Live (TTL) expires, the record value should be refreshed with the new IP address. If that doesn’t occur users may have to flush (clear) cache.
