What does a STUN server do?

A STUN server is a server that runs on the public network and replies to incoming requests. The responses it sends out include the public IP address the request was sent to him from. This effectively answers the question “what is my IP address?”

What is STUN 3478?

STUN is a protocol for the self-discovery of a client's public IP address from behind a NAT. A STUN server allows a computer on the internet to determine its own public-facing IP address. STUN uses UDP, and STUN servers typically listen for UDP requests on port 3478.

Is STUN server necessary?

STUN (Session Traversal Utilities for NAT)

This is needed for them to connect directly. A peer does not know its public IP address since that is handled by NAT and is beyond the knowledge of the peer. This is where the STUN server comes into the picture.

Are STUN servers safe?

Yes stun server are completely secure and the connections are encrypted. STUN servers are used to show the client that is behind a NAT or Multiple NATs what its own public IP and port number is, so that peer to peer connection is made possible.

Is Google STUN server free?

The Google STUN server is something you can freely use for development purposes, but, as a free service, there is no SLA.

Is STUN port 3478 TCP or UDP?

The standard listening port number for a STUN server is 3478 for UDP and TCP, and 5349 for TLS. Alternatively, TLS may also be run on the TCP port if the server implementation can de-multiplex TLS and STUN packets.

What is port 3479 used for?

Port 3479 Details

Apple FaceTime, Apple Game Center use ports 3478-3497 (UDP). Notes: Port numbers in computer networking represent communication endpoints.

Is STUN a TCP?

UDP/TCP/TLS: Typically, STUN uses UDP, TCP or TLS as its transport protocol. The well known UDP/TCP port for STUN traffic is 3478.

What is STUN IP address?

STUN provides the mechanism to communicate with users behind a network address translation (NAT) firewall, which keeps their IP addresses private within the local network (LAN). The initiating party sends a request to the STUN server, which maintains the IP addresses of the phone or computer (for video).

What is the difference between STUN and TURN servers?

STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) servers are both used in the signaling process but for different reasons. Before establishing a peer-to-peer connection, it is essential for servers to identify the IP address for each participant.

What does Unifi use STUN for?

STUN stands for Session Traversal Utilities for NAT and includes a set of protocols used in networking to better handle communication when going through network address translation (NAT). In simple terms, STUN provides a way for devices to securely communicate with other devices when they're located behind a router.

How do STUN devices work?

A stun gun is an Electrostatic Discharge self-defense device. A stun gun is hand held, and is applied by touching the electrodes to an assailant. The strong electrical signal disrupts the nerves that control muscles, and can cause intense pain.

What service is STUN?

(Session Traversal Utilities for NAT) An IETF protocol for real-time voice, video and messaging in an IP network. STUN provides the mechanism to communicate with users behind a network address translation (NAT) firewall, which keeps their IP addresses private within the local network (LAN).

What is STUN server in WebRTC?

Session Traversal Utilities for NAT (STUN) is a protocol to discover your public address and determine any restrictions in your router that would prevent a direct connection with a peer.

Is STUN a TCP?

UDP/TCP/TLS: Typically, STUN uses UDP, TCP or TLS as its transport protocol. The well known UDP/TCP port for STUN traffic is 3478.

Does WhatsApp use STUN?

Protocol Description

WhatsApp is a popular messaging and voice over IP (VoIP) service owned by Facebook. The WhatsApp STUN protcol detects messages and notifications.

What is the difference between STUN and TURN servers?

STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) servers are both used in the signaling process but for different reasons. Before establishing a peer-to-peer connection, it is essential for servers to identify the IP address for each participant.
