The following pdf gives a list of IP addresses of DocuSign servers:
https://www.docusign.co.uk/sites/default/files/Post_API_Certification20130522.pdf
Based on the information in this document:
1) to call the REST API in a production environment we have to use the hostname www.docusign.net
2) this server has the IP 209.67.98.12
Can we rely on this ? I need to be sure that the server to call will be always www.docusign.net and I need to know its IP address to properly configure firewalls.
Thank you
