Networking Requirements

HTTP Connections

HTTP(S) is used for connecting to the Phenix PCast™ Platform and delivering live streams.

Domain Protocol IP Ports
phenixrts.com HTTP/HTTPS 107.178.248.156 80, 443

Persistent Websocket Connections

Our Native and Web SDKs establish persistent web socket connection with the closest Phenix PCast™ Point of Presence for low latency communication between clients.

RTC Communication

For delivering real time stream, we rely on a combination of TCP and UDP connectivity.

Protocol Port
TCP 80, 443*, 1935**, 3389, 3390
UDP 443, 1024 - 65535
* Port TCP/443 is used as a fallback with TURN. It is less optimal than UDP delivery in most cases.
** Port TCP/1935 is used for RTMP delivery for old browsers that do not support real-time standards.

IP address blocks used by our servers can be downloaded here and are updated daily.

STUN Servers

We use STUN servers for discovery of clients. It is incorporated for compatibility reasons for web browsers. Having no access to these servers will not impact using the phenix platform directly but it may impact (e.g. slow down or block) some browser from using the phenix platform effectively.
