No, this is not permitted because our Services are hosted on in a virtual environment across many servers.
Due to load balancing or other server shuffling activities, the IP address for an API could change at any time without notice. You cannot rely on any IP address to remain static. The proper way to code to an Xignite API destination is via the API URL.
If you have any issues using an Xignite API, please send an e-mail to firstname.lastname@example.org
so that we can assist you.
