# STUN
Package stun implements Session Traversal Utilities for NAT (STUN) [[RFC5389](https://tools.ietf.org/html/rfc5389)]
protocol and [client](https://godoc.org/gortc.io/stun#Client) with no external dependencies and zero allocations in hot paths.
Client [supports](https://godoc.org/gortc.io/stun#WithRTO) automatic request retransmissions.
Complies to [gortc principles](https://gortc.io/#principles) as core package.
See [example](https://godoc.org/gortc.io/stun#example-Message) and [stun server](https://github.com/gortc/stund) for simple usage.
Also see [gortc/turn](https://github.com/gortc/turn) for TURN [[RFC5766](https://tools.ietf.org/html/rfc5766)] implementation and
[gortcd](https://github.com/gortc/gortcd) for TURN and STUN server. This repo was merged to [pion/stun](https://github.com/pion/stun)
at version `v1.19.0`.
# Example
You can get your current IP address from any STUN server by sending
binding request. See more idiomatic example at `cmd/stun-client`.
```go
package main
import (
"fmt"
"gortc.io/stun"
)
func main() {
// Creating a "connection" to STUN server.
c, err := stun.Dial("udp", "stun.l.google.com:19302")
if err != nil {
panic(err)
}
// Building binding request with random transaction id.
message := stun.MustBuild(stun.TransactionID, stun.BindingRequest)
// Sending request to STUN server, waiting for response message.
if err := c.Do(message, func(res stun.Event) {
if res.Error != nil {
panic(res.Error)
}
// Decoding XOR-MAPPED-ADDRESS attribute from message.
var xorAddr stun.XORMappedAddress
if err := xorAddr.GetFrom(res.Message); err != nil {
panic(err)
}
fmt.Println("your IP is", xorAddr.IP)
}); err != nil {
panic(err)
}
}
```

# Stability [](https://github.com/mkenney/software-guides/blob/master/STABILITY-BADGES.md#mature) 
Package is currently stable, no backward incompatible changes are expected
with exception of critical bugs or security fixes.
Additional attributes are unlikely to be implemented in scope of stun package,
the only exception is constants for attribute or message types.
# RFC 3489 notes
RFC 5389 obsoletes RFC 3489, so implementation was ignored by purpose, however,
RFC 3489 can be easily implemented as separate package.
# Requirements
Go 1.14 is currently supported and tested in CI. Should work on 1.13.
# Testing
Client behavior is tested and verified in many ways:
* End-To-End with long-term credentials
* **coturn**: The coturn [server](https://github.com/coturn/coturn/wiki/turnserver) (linux)
* Bunch of code static checkers (linters)
* Standard unit-tests with coverage reporting (linux {amd64, **arm**64}, windows and darwin)
* Explicit API backward compatibility [check](https://github.com/gortc/api), see `api` directory
See [TeamCity project](https://tc.gortc.io/project.html?projectId=stun&guest=1) and `e2e` directory
for more information. Also the Wireshark `.pcap` files are available for e2e test in
artifacts for build.
