Overview

Package resolver provides interface (and default implementation) to retrieve public network address.

Currently there are two default implementation of resolvers:

• Using STUN server
• No-op resolver which returns socket listen address

Usage:

var conn net.PacketConn

// get connection anywhere

r := resolver.NewStunResolver("")  // Using default stun server
publicAddr, _ := r.Resolve(conn)

fmt.Println(publicAddr)
