Network Traversal Service Regions


Network communication to and from Twilio's TURN servers will originate/terminate from the static IP address ranges listed below for each region. Refer to these ranges if you need to configure your local network to allow communication or apply Quality of Service routing rules to communication with Twilio.

Note: Twilio STUN servers also use the same static IP address ranges.

Your network infrastructure should be configured to allow connections to and from the above addresses on the following ports:

PortProtocol
443TCP (TURN TLS)
3478TCP, UDP (TURN)
5349TCP (TURN TLS)

Twilio's TURN servers will allocate peer relay ports in the UDP 10,000-60,000 range.
