Which IP addresses should I allow when using Vonage APIs?


Question

What IP addresses do I need to add to my firewall if I'm using Vonage APIs?

Applies To

  • Vonage APIs
  • IP Addresses
  • Firewall Settings

Answer

If your platform restricts the inbound traffic it can receive using IP address ranges (typically via firewalls), you'll need to add the following IP addresses to your allow lists, depending on the API products that you use. These IP ranges may be used for receiving HTTP callbacks, webhooks, WebSocket connections, SIP, and RTP/Media.

Traffic from Vonage's API platform might come from any of the IP addresses included in the referenced subnets. For all of our non-Voice products, the HTTP Callbacks IP ranges will be sufficient.
