Hello, is there any documentation regarding the IP ranges that Vapi sends requests from? We have an IP allowlist for Azure App Services. I've been sending test requests to RequestBin and I've been getting a number of different client IP addresses.

Hi there! 👋 I understand you're looking for IP ranges to configure your Azure App Services allowlist. Unfortunately, I couldn't find documentation listing specific Vapi IP ranges for outbound requests. However, I can help with the recommended approach for allowlisting Vapi services! According to the information I found, Vapi uses dynamic IPs, which makes IP allowlisting impractical. Instead, the recommended approach is to whitelist domains rather than specific IP ranges. Specifically, you should whitelist

vapi.ai

and *`.vapi.ai`** domains for your Azure App Services. As noted in [Discord discussions](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1333797946440941639), "we have dynamic IPs so your client has to whitelist our domain and possible domains. You can ask them to whitelist vapi.ai, and *\.vapi.ai**." This explains why you've been seeing different client IP addresses when sending test requests to RequestBin - it's because Vapi operates from dynamic IPs rather than a fixed range. Is there anything else you'd like to know about configuring your Azure services to work with Vapi?

We don't have any static IPs or fixed sets of IPs allocated for our resources. Instead, they're all dynamic, so you'll need to whitelist our domain name.
