 =====Description=====
 Goal is to provide a Pico with an ethernet connection W5500.\\
-The W5500 is controlled by SPI and the WIOpico-ETH will use the same pan mapping as the [[:wio:wiopico-io16can-en|WIOpico 16 I/O CAN]].\\

  \\
 =====Features=====
-  * Looking up the Rocrail server by mDNS.
+  * Only available for Pico's without WiFi shield. ✔️
-  * Transparent communication between WiFi and Ethernet.

+=====Ethernet Library=====
+To be able to set the hostname the Ethernet Library must be modified.\\
+In ''Arduino/libraries/Ethernet/src/Dhcp.cpp'' the following code must be added/extended:\\
+<code cpp>
+const char* g_DhcpHostName = ""; // ***** NEW code line
+void DhcpClass::send_DHCP_MESSAGE(uint8_t messageType, uint16_t secondsElapsed)
+</code>
+<code cpp>
+	// OPT - host name
+	buffer[16] = hostName;
+	// ***** start NEW code lines
+	if( strlen( g_DhcpHostName ) > 0 ) {
+		buffer[17] = strlen(g_DhcpHostName);
+		strcpy((char*)&(buffer[18]), g_DhcpHostName);
+	}
+	else {
+	// ***** end NEW code lines
+		buffer[17] = strlen(HOST_NAME) + 6; // length of hostname + last 3 bytes of mac address
+		strcpy((char*)&(buffer[18]), HOST_NAME);
+		printByte((char*)&(buffer[24]), _dhcpMacAddr[3]);
+		printByte((char*)&(buffer[26]), _dhcpMacAddr[4]);
