EthernetUDP.remoteIP()

Description

Gets the IP address of the remote connection. This function must be called after [UDP.parsePacket()](http://energia.nu/reference/ethernet/ethernet_udpparsepacket/ "Ethernet_UDPParsePacket"){.wikilink}.

Syntax

UDP.remoteIP();

Parameters

None

Returns

4 bytes : the IP address of the remote connection

Example

#include <SPI.h>
#include <Ethernet.h>
#include <EthernetUdp.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 177);
unsigned int localPort = 8888;      // local port to listen on
// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;
void setup() {
  // start the Ethernet and UDP:
  Ethernet.begin(mac,ip);
  Udp.begin(localPort);
}
void loop() {
int packetSize = Udp.parsePacket();
if(packetSize)
{
  Serial.print("Received packet of size ");
  Serial.println(packetSize);
  Serial.print("From IP : ");
IPAddress remote = Udp.remoteIP();
//print out the remote connection's IP address
Serial.print(remote);
  Serial.print(" on port : ");
  //print out the remote connection's port
  Serial.println(Udp.remotePort());
}
}
