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?”

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.

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.

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.

What is difference between STUN and TURN server?

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.

Is STUN TCP or UDP?

STUN messages are sent in User Datagram Protocol (UDP) packets.

What is STUN in VoIP?

A STUN (Session Traversal of User Datagram Protocol [UDP] Through Network Address Translators [NATs]) server allows NAT clients (i.e. IP phones behind a firewall) to setup phone calls to a VoIP provider hosted outside of the local network.

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.

Why is STUN more preferred than TURN?

TURN is preferred because it is capable to traverse symmetric NATs too. However, STUN is useful to speedup the connection out of getting immediate candidates when users are sitting behind same NAT e.g. LAN.

Is STUN peer-to-peer?

STUN and TURN servers are two types of WebRTC signaling servers that can be used to create your peer-to-peer (P2P) connection when you are building a real-time communication application.

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 UDP or TCP?

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. For a client to use STUN, their network must allow UDP traffic.

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.
