HTC Vive minimum specs

Oculus minimum specs

Network Requirements


Your firewall should allow outbound connections to the following ports:

  • 443 TCP
  • 46889 TCP/UDP

Connection Quality

Vizible requires a fast and reliable Internet connection. At a minimum, we suggest 5 Mbps upload/download per user and a latency (or “ping”) of less than 30ms.

Advanced Network Configuration

Server Addresses

Customers in secure environments may require their firewalls to be locked down so that Vizible connections are permitted only to specific IP addresses.

Here are the addresses used by port 46889 Vizible client/server communication:

HTTPS requests over port 443 are made to the following hosts:

  • North America:
  • European Union:
  • Asia:

Fallback Ports

In the event that Vizible cannot connect via port 46889, it will attempt other ports as a fallback mechanism. This includes port 443 UDP/TCP. If port 46889 cannot be opened, this port may be opened on a firewall instead.

Appliance Configuration

The Vizible appliance is a hardware device that allows organization to run their own copy of Vizible on their local network. It does not require external access to the Vizible cloud servers.

The appliance operates locally on the following ports:

  • 46889 TCP/UDP
  • 8080 TCP
  • 8081 TCP (management interface)
  • 1900 UDP ( service discovery)

Clients require the following ports to be open for service discovery:

  • 1900 UDP inbound
