Peer-to-Peer Detection with DPI

Applications such as Twilio use peer-to-peer signaling protocols to establish direct connections between devices, often leveraging dynamic IP changes. Netify protocol detection is the best way to properly track this type of network session.

Twilio Network

Some organizations deploy all or parts of an application solution through their own infrastructure instead of third party hosting providers like AWS or Google Cloud Platform. The following is a sample of active IP addresses on the Twilio Network.

208.78.112.65	AS394434	Twilio	208.78.112.0/23	United States
208.78.112.66	AS394434	Twilio	208.78.112.0/23	United States
