Vonage does not require your originating IP address to be allowed to use the API Platform. We will validate your bind request based on your system_id (API_key) and password (API_secret).
If you would like Vonage to add additional security and allow your account to bind from only certain IPs, please contact our Support team at: support@nexmo.com. Currently, product supported for such configurations are:
SMS(HTTP/SMPP)
